Dragon Ball GT/Headscratchers

"Gohan: Yeah, I know it's weird, but these two kids who are clearly young enough to be my son and daughter are really my mom and dad. N-no, I don't have legal papers on them, nor am I their legal guardians because I'm their son! H-hey! Why are you reaching for that phone? I-I'm telling you the truth, these two kids are actually my parents! C'mon, they'll vouch for me! Capsule Corps. News Anchor: A local man named Gohan has been taken in custody for allegedly kidnapping and brainwashing two innocent children into thinking that he's their son, and that they were once fully grown adults who shrunk themselves thanks to a wish they made to...eh...a dragon that came out of seven dragonballs . He's now in an asylum pending review, while the children are in the care of a children psychiatric ward."
 * GT is perhaps one of the few shows with a Gainax Beginning. First and most important, why is Pilaf even alive? Considering all that happened in Z, he should have been killed by Buu and not revived later. No Pilaf, NO GT!
 * Gainax Beginning, Gainax Middle, Gainax Ending. Does DBGT stand for Dragon Ball, Gainax Tour? Well, Look around.
 * Goku's skin tone has completely changed to a very tanned complexion for no reason. Nobody else seems to have had any such issues.
 * Why did Goku lose his instant transmission technique when he was turned into a child? Apart from being a convenient way of justifying the "Grand Tour", why could he only use it as a Super Saiyan 4?
 * The start of GT. Goku and Uub emerge from the Hyperbolic Time Chamber after their training. Never mind what Goku said earlier on that a person can only enter it twice in a lifetime or only for two years. And for some reason the whole chamber has changed from a featureless white landscape to some sort of asteroid belt-esque environment. If Goku's power level has increased the way he claims while fighting Rildo, just how long were those two training in there?
 * And their fight is damaging the lookout on the outside, without the need to punch dimensional holes through it. Either Goku in base form and Uub are far stronger than Majin Buu fused with everyone, or something just doesn't add up.
 * What does being in a smaller body have to do with losing the ability for Instant Transmission, Goku? An Ass Pull only to be restored later by another Instant Aging Ass Pull with Super Saiyan 4?* GT doesn't even make sense on the relative strengths of the characters. When Kaioshin wants to restore Goku's power, Old Kaioshin tells him there's no way he can replenish the energy supply of a Super Saiyan 4. But next episode we see 3 Super Saiyans and a normal Pan do precisely just that, all of whom shouldn't even add up to Super Saiyan 2! I mean it should reasonably take at least 10000 of them to match the power of a Super Saiyan 4.
 * It gets worse in the Shadow Dragon saga where just the 3 Super Saiyans alone have enough energy to overload Goku beyond his normal Super Saiyan 4 limits, never mind that GT shows him to be far stronger than all of them in base form!!
 * This is another one on Power Levels. Kid Goku in base form beats Rildo's base and claims it was stronger than Buu!!?? That's an increase beyond Super Saiyan 3! And so Kid Goku being stronger than 2 Super Saiyan 2s? In DBZ, after seven years of afterlife training, Goku's real boost came from Super Saiyan 2 and 3. His Super Saiyan form was only marginally stronger in Buu Saga and the exponential power growth in any level more or less stopped once he mastered it.
 * Speaking of Rildo, if he's stronger than Buu, then how do you reconcile that with what happened in Z. I mean are the Kais not even remotely worried about the fate of the universe?
 * Super Saiyan Goku seems to be absurdly stronger than what the Super Saiyan level itself ought to permit. On the other side we have Vegeta, who in spite of all his training is somehow far weaker at Super Saiyan 2 and goes out in one shot against Super 17!
 * And that's not very consistent either. Base Goku can defeat Cell with the audacity of riding Frieza's disks like a surfboard, but can't resist when he's frozen in ice and relies on natural body heat to melt it. Yeah...now we've seen everything.
 * Majuub is yet another mystery. He fares much better against Baby Vegeta than Super Saiyan 3 Goku. In Super 17 saga, he goes out in one hit, proving himself to be far weaker than Super Saiyan Goku, who puts up a decent fight. What just happened to him over a few weeks?
 * Speaking of Majuub, you wonder why being stronger than Gohan, Goten, Trunks and possibly even Vegeta, he isn't giving any energy to Goku. Despite absorbing Buu, he seems to lack the ability to regenerate. What to speak of injuries, he can't even replenish his power the way Kid Buu could.
 * Majuub was turned into chocolate and eaten. He can reverse the transformation, but he waits till Baby Vegeta's become a full ape and then causes a significant amount of internal damage. What was he doing till then? If he had done that while Baby was still down to size, it would have been game over then and there, (though the implications would have been Body Horror).
 * Why was Majuub not able to beat super 17 all my himself? Both half of super 17 are weaker than ssj2 and both half of majuub are about ssj3 level.you do the math something doesn't add up.And yet Goku as ssj1 did better than him when fighting super 17 .looks like only Goku benefited from all that training they did.
 * Isn't there any way to destroy the dragonballs without killing their creator? Can't Piccolo just deactivate the black star Dragonballs, or at the very least modify them? How come he just forgot about them like that? In that case, the whole plot in DBZ of getting Dende to be Earth's guardian would be totally unnecessary, wouldn't it?
 * For some reason, characters in GT, while stronger in theory than Z in fact seem much weaker when you compare the intensity of the fights to DBZ.
 * I must say I disagree with this point completely - the fact they are more powerful is why the fights are less intense. They now do so much damage with each punch; cause so many injuries with one ki wave that the battles are over far quicker. Lets take a real life example: World War 1. Our lack of technology, tactical planning, foresight and abundance of manpower still led to the second most devastating war in history, stalemating into four years of trench warfare. Now, imagine if you will, what would would happen if WW 1 was repeated in the 21st century? nuclear warfare. I can guarantee the main battle wouldn't last four years just as I can guarantee if you put the Dragonball GT era Z Fighters against any of the Dragonball Z era enemies it wouldn't have been a Saga-spanning 30 episode battle.
 * It's the intensity of the battles and the collateral damage it just doesn't add up to things like Goku's base being now as strong as Majin Buu. Most of the fights with the Shadow Dragons for one. Omega fires blasts strong enough to blast both the Super Saiyans out of their senses, they end up flying into buildings where they barely break the glass. Also Frieza lifted far bigger things than Goku did as a Super Saiyan 4. Contrast that to the other headscratcher about the fight with Android 17, which seems to be almost exaggerated by comparison. No it doesn't seem like nuclear war to WW 1.
 * Piccolo was hurt by a Bebi possessed Gohan way back in Baby Saga. He's thrown into a trench and is gone for the rest of the saga. Then just before Goku leaves the exploding Earth, Piccolo appears again, still injured, despite the fact that he should be able to regenerate. What, did he just get so frustrated by being Demoted to Extra that he gave up the will to live all together?
 * Just one major issue. Planet Plant/Vegeta's gravity is 10x that of earth as mentioned in Dragonball Z. So how come Mr. Satan or for that matter any of the human beings who were transported to the planet never got crushed by the heavy gravity or for that matter didn't even notice it?
 * Speaking of which it's a headscratcher how a planet with more gravity that the earth could orbit it.
 * It has more gravity on the surface. The planet could be much denser than Earth but also much smaller, giving it a smaller mass. This would give it larger gravity on the surface but less of a pull at long distances.
 * Mr. Buu turns Satan and Pan into candy and eats them to keep them safe(!!??) inside him so they can get to planet Vegeta. But even more, Mr. Satan seems to be quite ok and even speaks as a piece of candy. Who was the only one powerful enough to do things like that before? Vegetto... What?
 * I'm going to guess the handwave here is that because Buu wants him to retain his free will as a candy; Hercule has no problem whatsoever in doing it. You could also say that seeing as Vegetto was transformed by Super Buu fused with Gohan/Piccolo/Trunks/Goten as opposed to the relatively weak fat Buu it's far easier to resist whatever magics are behind this technique. For the record I agree with you that it's another one of GT's notorious plot holes but if you stretch credibility to breaking point it is possible to explain this in-universe.
 * The fight with Super 17 is grossly exaggerated in effects compared to all the other fights in the DB universe. One punch from Goku throws Super 17 to the other side of the planet and one from the android sends him into space and beyond. Ki blasts are now able to circumnavigate the globe. Compare this with the Shadow Dragon saga where Super Saiyan 4 Goku is trying to run for his life from Omega Shenron's blasts just powerful enough to blow up parts of the roller coaster in an amusement park.
 * Anyone noticed that once 4 Super Saiyans restore Goku's Super Saiyan 4 power, he has no injuries on him, despite the fact that he was badly hurt just moments before?
 * Goku can't properly sustain Super Saiyan 2 in his kid body? What about Gohan way back in Z?
 * Why was Piccolo in Paradise instead of with Grand Kai? Was it just for drama so he'd have to be trapped in Hell instead of just going down there like Pikkon and Goku have done?
 * And why does King Yemma refuse to send Piccolo down to hell, prompting Piccolo to wipe out a lot of the afterlife...that was not a problem in DBZ.
 * In DBZ, being killed in the afterlife means becoming Deader Than Dead. In GT, Goku kills Frieza and Cell, and they just regenerate because they're already dead. WHAAAAAT?
 * Why did they even try to used the earth dragon balls to revive krillin anyway? He already been revived by them once.So they can't do it again! It wouldn't had worked even if the earth Dragon balls had not been over used.
 * Why didn't they just kill Dende when the Shadow Dragons popped up? Or use the Namek balls to wish the negative energy away? If they killed Dende, it would deactivate the balls, killing the dragons. Then go to Namek, wish him back, with the stipulation that the Earth Dragon Balls don't reactivate. Then make new Dragon Balls, and bring everyone back with them.
 * Oh good idea. Ask a bunch of Blood Knights who are also very sensitive about their friends and loved ones being hurt, to kill one of their friends so they can avoid fighting some really powerful opponents, and pray to God you won't get a boot to the head as an answer.
 * Killing Dende would have killed the Original Shenron effortlessly but it is pretty ridiculous to imagine that the Shadow Dragons weren't completely self-sustaining entities; realistically the last point you could have executed that plan was when the final crack appeared on the final Dragonball. Incidentally, if it was a viable tactic you wouldn't have needed to kill Dende at all but rather destroy the Shenron Toy that is kept upon the Lookout.
 * The whole fight between Goku and Super 17. How can Goku be such The Ditz not to confirm that Super 17 was absorbing all his energy after all his experiences with the Androids, until he spent almost all his power making Super 17 stronger than him?
 * Speaking of Super 17, Goku's so weak at the end he can barely stand. Then the next minute he senses Super 17 can't fight while absorbing and somehow summons enough energy in base form to put a Super Dragon Fist and multiple Kamehamehas through Super 17 who's supposed to be stronger than Super Saiyan 4.
 * Where did all the movie villains come from in that saga? Of all things, please, please, don't tell me they actually recycled non-canon script?
 * Golden-ape Baby needs two full power Kamehamehas to blow the earth? And when he's powering up his Galic Gun, Goku just stands there doing absolutely nothing except listening to World of Cardboard Speech until Baby actually fires the blast, after which he seems to realize he has to stop it. And he instead gets hit before he can power up another blast. What would have been the scene for one more of DBZ's Beam struggles just never happened.
 * In the Shadow Dragon saga, the whole fight against Rage Shenron. Goku goes from base to Super Saiyan 4 and the power change isn't that convincing. Rage Shenron uses slime to absorb electricity from a puny source like the city's power grid, which doesn't even generate sparks by Dragonball's energy standards and then becomes strong enough to stop a 10x Kamehameha dead in it's tracks and surpass Goku (who's long since passed the point where he should be able to blow up multiple planets in base form) and Pan. What happened to the Law of Conceivable Conservation of energy?
 * Speaking of that Kamehameha, it was at full power and was thrown right back at him. We expected at the very least that the whole solar system ought to be blown up. All we get instead is a ruined street, a few broken buildings and Goku back to his child form. Never mind that afterwards he has enough power to fight 4 more dragons at Super Saiyan 4 without so much as a healing or a senzu bean.
 * And they're only saved by Deus Ex Machina raining down and shorting him out. Absolutely disgraceful.
 * When the Shadown Dragons are released, the rest of the cast goes home without so much as an offer to help and it's all up to Goku to go fight them? Were they happily taking a nap when he was fighting 6 out of 7 dragons all by himself?
 * Shadow Dragon Saga. How did Goku's eyesight just come back by itself all of a sudden?
 * Yamcha has said several times he wanted to get married more then anything else, got giddy at the thought of starting a family as late as the Android saga, and Future Trunks briefly mentions that Yamcha finds a new love in his timeline. With these things in mind why is Yamcha consistently shown to be single, even shown to be living alone in Diablo Desert with Puar back in Dragon Ball GT? Are we to believe that Yamcha just gave up on his lifelong dream in addition to already giving up on Martial arts?
 * The canonicity of DBGT is debatable. At the end of the Cell Saga Yamcha mentions a girlfriend, so he was not single. Maybe he was unlucky and they broke up during the timeskip (since she's never seen nor mentioned again).
 * The 10x Super Kamehameha isn't very consistent. It started out as two blue spheres combined into one (actually this makes it less powerful than charging an attack with two hands together). And while it does nothing to hurt Baby at first, after Baby's fired an equally powerful blast at Goku and knocked him flat, it suddenly kicks in and attacks him from inside out, trashing him. If the dub line is to be believed, Goku was expecting all this to happen. What in the world was that all about?
 * And then later in the series turns into this orange red beam.
 * The level of collateral damage just doesn't add up to the characters' power levels and the energy they ought to be putting into their attacks. In most cases, they're actually causing less damage on the Earth then most fights in Z. I can understand the So Last Season thing in Dragonball Z, but this is going beyond all reason.
 * The more you look at GT, the worse it gets. In the last episode we see Yamcha in the desert and Tien and Chaoutzu training off near a waterfall. Oh yeah, they were totally not bothered by all that happened in the Baby Saga, being possessed, the earth exploding, Super 17 and the Dimensional Collapse and all the villains leaving hell, and least of all the Shadow Dragons and all that negative energy around the globe. Talk about throwing in the towel. GT just forgot they were even there!
 * How the hell did Dr. Gero and Dr. Myu manage to make a perfect copy of 17? In hell?!?
 * Why didn't everyone use the Blutz Wave Generator, shouldn't Bulma have given everyone a chance after seeing what it did to Vegeta? I don't get why she'd use it on Shenron when she could've covertly enhanced everyone with steroid waves.
 * At the very least she could have used it to restore Goku's and Vegeta's energies for another fusion. But no.
 * Just what happened to Gohan's Mystic power-up when GT rolled around? Did he lose it when he got pulled out of Buu? It just faded away? He was just damn uninterested in fighting anymore when he grew up?
 * The third one, methinks. He always was the more intellectual one in that family. Besides, he's married to Videl now, right? Anyway, GT wasn't written by Toriyama, so we can probably just say that they Did Not Do the Research and drop this one in Canon Discontinuity. They seemed more interested in turning Goku into a kid and inventing SSJ4 then expanding on Gohan's abilities.
 * Or remembering that he couldn't turn Super Saiyan. (The old Kai told him to try and do 'that super-saiyain thing'. He turned Mystic, with a different hair style to normal, that of his SSJ2 form, but not blonde.)
 * The unfortunate real world answer is that its both a plot hole and a willing part of the script writers to make Goku the hero of GT. However, to attempt to explain this in-universe it relies on working out what exactly the Mystic Form actually is. If its a power up similar to when Guru unlocked his Hidden Potential, then there is a simple answer because it happens to be rooted in previous canon. During Dragon Ball Z its noted that his Super Saiyan 2 form had considerably weakened because he was no longer training; its not that he lost the Mystic Form, he was always using it throughout GT - its just weakened to the point where Goku and Vegeta have surpassed him. If on the other hand its a Transformation similar to Super Saiyan or the Kaioken then it once again comes back to Gohan's lack of training. Like his weakened Super Saiyan 2 form, it may now be impossible for him to transform given the massive energies required - it does after all surpass Super Saiyan 3.
 * There's also the WMG (which, when you think about it, makes sense) that Pan accidentally took it. She's easily at the power level of Goku when he fought Androids 19 and 20 (proven by her easily beating Android 20). No matter how much training she did, and how many times she almost died, there's nothing that could have logically elevated her to that level. Mind you, that's a power level stronger than Freeza. From a 10 to 12 (about 2 years had passed by that point, so if she was 10 at the start, she would be 12 by then) year old girl.
 * That's not unnatural. Goten and Trunks' base power at the end of Z was more or less at Frieza's level. Though from what we've seen in Z, that much increase really comes from mastering the Super Saiyan form, which apart from making it ultra powerful and efficient, seems to boost the base form's power proportionately as well, as Goku demonstrates in the afterlife. Before any of them made Super Saiyan as efficient as their normal state, they absolutely couldn't get to Frieza's level and beyond without going Super Saiyan.
 * The last episode. Ok, so Shenron can't grant any more wishes, so why not go Namek and take one wish from Porunga to restore everyone killed by the Shadow Dragons? What is even the need for the Deal with the Devil that Goku makes at the end?
 * Some of the GT endings (example: http://www.youtube.com/watch?v=INND 4 rkd 8 Qw) include a sequence in which most of the good guys walk or fly past the screen. Quick question, what the hell is BABY doing there?! He's just evil, he doesn't redeem himself, he has no reason to be there. I don't get it.
 * That specific scene seems to be a homage of the illustration in the old DB volumes. They included both heroes and villains together. Speaking of GT endings, the second one is about couples: Goku and Chichi, Vegeta and Bulma, Gohan and Videl, Krillin and Number 18 and... Goten and Trunks? Are they appealing to the fangirls there or what?
 * No, they were showing scenes of character pairs doing everyday stuff. The only other characters who would fit with Goten or Trunks would be Pan or Goten's Shallow Female Love Interest, they were better just with each other.+
 * That's the most likely truth. Still, it's funny they're the only pair who isn't a couple.
 * They're a couple in the same way Scrubs' John Dorian and Christopher Turk are.
 * Indeed, it's just guy love... between two guys.
 * Another GT problem. How could the Black Star balls have been made before Kami separated from Piccolo? Kami separated from Piccolo so that he could become the resident god. Don't you need to be the resident Kami to make the Dragon Balls in the first place? When could he have possibly made the black star balls?
 * IIRC, the Black Star balls were Kami's Dragon Balls, beta version, with one giant drawback. Of course, how one could figure out that drawback without a planet or three going "Boom"... let's just not examine this too closely.
 * If I remember correctly, Pilaf said they were made before the split. Besides, if they were solo Kami's, then the balls would be inert, since by that time, Kami has long since fused with Piccolo.
 * Also, Pilaf's an idiot.
 * You don't need to be Kami to make the balls, you just need to be from the Dragon Clan. Guru wasn't Kami of anything, if you recall. That explains why the Black Star balls were active after Kami had fused with Piccolo, because that was his original state when he created the balls
 * The Black Star balls were made by the Nameless Namek; they became inert when he split into Kami and King Piccolo. Remember Piccolo Jr ceased to exist after the Cell saga from a biological point of view - as far as the balls are concerned he is the original creator. It's clearly said in the episode they appear. Incidentally it actually makes perfect sense from a real world perspective; the Nameless Namek was as strong as Android 17 AKA a thousand times stronger than Guru or Kami. Makes sense his Dragon Balls would be stronger in every single way.
 * The Black Star Balls are too nonsensical to think about them. For instance, how come they were never detected after the Nameless Namek was reborn in the middle of Cell Saga? The original Dragon Balls have been collected at least thrice after that (after Cell's death, after Majin Vegeta's killing spree, and at the end of the Buu saga) and they never found out about the Black Balls via the radar. Also, how could Red Shenlong affect Goku's body (and power) since he's clearly far stronger than the creator? Those are pretty big Plot Holes.
 * Even if pilaf knew about the black star dragon balls how did he knew that piccolo and kami refused 22 years ago?
 * Why wasn't piccole at the lookout when pilaf attacked it.when we last left him in dbz piccole lived at the lookout but when GT got started he was no where to be seen. also why didn't mr.popo or dende try to help goku fight off pilaf and get back the black star dragon balls.
 * How was it that Pilaf,Shu,and Mai was able to hold Goku off long enough to summon Black Star Shenlong? I know Goku was tired after fighting ubb.but he and uub was able to heavily damage the lookout while in The Hyperbolic Time Chamber IN BASE FORM Without the need to punch dimensional holes through it like gotenk and majin buu,Yet couldn't beat pilaf and his mooks in under 30 seconds? Mr.popo alone could have handle them. as meantion before Why Mr.popo and Dende didn't try to get back the Black Star Dragonballs while Goku was fighting them? they just stood there!
 * How is it that Android 18, after lecturing Super 17 on his "cowardice" for allowing mad doctors to decide his actions, witnessing his clear look of turmoil over it, and seeing him finally snap and kill Dr. Myu after the latter runs his mouth, never actually thinks about trying to convince her brother to stand down? We could've seen a Heel Face Turn which would produce a very valuable ally that could've come in handy for the final arc so that Goku didn't have to do 90% of everything. (Wait, maybe I just answered my own question…)
 * That you did. Dragon Ball GT was designed to make Goku the hero and everyone else seem like losers. At the end of Z Gohan and Gotenks were the strongest fighters in existence. Come GT and instead of expanding their characters, the writers pull Super Saiyan 4 out of their ass which just happens to make everything and everyone before it look redundant. Even after other Super Saiyan 4's appeared he was still responsible for the killing blow against the most powerful enemy in history. And what was the final shot of the series? Goku the only Z Fighter alive. Basically the writers sought out anyone or anything as strong as Goku and ground it under their heels.
 * Wait... Wouldn't SSJ3 Goku be just as strong as, if not stronger than, SSJ3 Gotenks? Not just that, but Vegito was far outclassing Super Buu after it absorbed Gohan (who recently had his full potential unlocked), even before turning into a Super Saiyan. Plus, even without the Potara, Goku and Vegeta could still fuse into Gogeta via Fusion Dance, if Goku could convince Vegeta to...
 * SSJ Gotenks was roughly even/superior to SS3 Goku. Goku was scared to fight Super Buu, and SS3 Gotenks dominated him. SS3 Goku is nowhere near SS3 Gotenks. Base Vegetto beating Super Buu w/Gohan is filler, in the manga he turns Super Saiyan immediately.
 * I agree with the previous poster - Gohan and Gotenks were the strongest fighters at the end of Z. There is absolutely no evidence outside of the movies that Vegeta knew and/or could perform the fusion dance reliably before GT which takes Gogeta out of the equation, the Potara earrings were destroyed meaning that Vegetto was for all intents and purposes dead and Gohan, already as powerful as Super Buu, still had both his Full Power and Super Saiyan 2 transformations in reserve. Fact is, Goku got lucky against Kid Buu. If it wasn't for the Spirit Bomb and his health boost from Porunga Goku would have been annihilated.
 * Wasn't it stated that the Fusion Earrings lead to a stronger form than Fusion Dance did? So even if Gotenks reached SS 3, wouldn't Vegito still be classified as the strongest being in (canonical) DB lore?
 * The last part of our Gainax Ending. Goku has no tail if you observe. Only God knows why. Whether he's even alive or dead is also a big mystery.
 * Thinking about it now, why couldn't they use Earth's normal Dragon Balls to wish back the Black Star Dragon Balls? It would've made a lot more sense to try to attempt to find the regular balls scattered across the planet before time ran out than it would've to build a ship and travel in space to who knows where to find the other set. Even if they couldn't wish the balls back, they could've at least asked for some form of advanced teleportation that'd let them easily arrive at the places with the balls, especially since Bulma somehow designed a radar that was able to detect the balls throughout space. Granted, we all know what happened the first time they actually tried to use the things in the entire series (if I'm not mistaken; Didn't they use new Namek's Dragon Balls to wish Earth back after Baby Vegeta used the Black Star Dragon Balls again? Soon after Baby was defeated, they had to evacuate Earth and I doubt they took the regular Dragon Balls with them), but the main characters couldn't have possibly known that at the time.
 * Also, in regards to the Black Star Dragon Balls being used again, why didn't the time needed to gather them again reset?
 * At least in the dub, it did. The Baby thing lasted far longer than it seemed.
 * The Shadow Dragon Saga again. While fighting against Naturon Shenron, Goku has trouble pushing a building in base form. And he's supporting the entire weight of it by pressing against window glass, so yeah, it must be Made Of Unobtanium, if not at least very strong glass. Then he has to go to Super Saiyan 4 just to lift it, which he and Piccolo or anyone else could have done waaaaaaayyyy back in DBZ's Saiyan Saga.
 * Why did Goku age back to adulthood when in SSJ4 form? Was it just Rule of Cool, or did it have an in-universe justification?
 * If I recall correctly, it was because his Super Saiyan 4 form was stronger than the Red Shenron. That may just have been Fanon, though.
 * Which is itself a pretty bland Hand Wave. There's no way for the Nameless Namek to be stronger than Goku SSJ3, or else Piccolo should have been able to fight with Fat Buu. I guess it's another Plot Hole for Dragon Ball GT.
 * Not really. Shenron can't affect anyone who's stronger than its creator, but was it ever stated that the Black Star Shenron had the same limitation? It could be that, as an unofficial (non-Kami/Guru/Planetary Sponsor) dragon with huge drawbacks, it could affect anyone who wasn't stronger than itself. That's starting to get close to Fan Wank, however, and is completely invalid if it was stated to have the same limitation and completely moot if it was a different reason.
 * I always thought that Goku's SSJ4 form was so strong, it could resist the Dragon Ball's powers.
 * Ass Pull people, that's the truth. They made Goku a kid because they thought DBZ was too much of serious fighting and they wanted to go back to the DB days. Then they realized it was a very bad idea, as even the audience began losing respect for Goku like Pan does, so they tried to go back to the DBZ ways. They didn't really think of any other way except to throw in Instant Age Settings and Instant Tailor for SSJ 4.
 * While Gohan's advice to Goku to 'just grow up like any other child' is sound, what's to stop them from collecting the regular Dragonballs to wish Goku back to adulthood again?
 * Or if a wish from the Black Star Dragonballs overrides the Red Star Dragonballs somehow, what was stopping Chi Chi from wishing herself younger? after all they did first meet as small children (and indeed proposed to each other which Chi Chi took very seriously well into her teens) and it's not as if Chi Chi still has any dependants to care for. Even if you argue that Chi Chi would be Squicked by the thought of being a little girl once again, why she didn't revert to her teens when Goku hit 16 for example is anyone's guess. As things stand Goku apparently accepted being the carer of an old lady (unless he ran off again of course) and Chi Chi apparently just accepted her death by old age despite having the potential access to seven magic balls that could restore her youth.
 * Well, Chi-Chi's been established as a woman who wanted a regular family, that likely includes husband she could grow old, and eventually die of old age with. The fact that he's gone and gotten himself turned into a kid again is frankly, and rightfully so, very stupid; and the idea that she has to cater to his whims, including using the Dragonballs to turn herself into a child again is, again rightfully so, very selfish. Goku may have been fine with the prospect of having to relive his childhood and adult years (with the retained memories of his first time growing up), but she wasn't. Also, think of Gohan and Goten. Can you imagine how they'd have to explain it to their superiors? To...anyone?
 * Hours later*

"Gohan: *transforms into Super Saiyan 2 and bitchslaps the wall to pieces*"
 * and then later he could just

while "Vegeta: *Super Saiyan* will you people PLEASE stop doubting anything involving Kakarot's family and friends? I mean, the world has blown up about 8 times in my lifetime, hell, I almost did it once myself about 20 years ago! Kakarrot has a monkey tail and can do this little transformation deal, too, actually being able to go about 5 levels of upgrade HIGHER than me, and you've all actually SEEN this dragon at least twice! I think we're WELL past the point of "believe anything out of that family's mouths"!!!!!!"

"Yamcha: Actually, the dragon has been summoned more than twice by now. I'd wager a few dozen times at least, so...yeah, there's no excuse to not knowing about the dragonballs."

"Krillin: Seriously. I mean, do you lot have a poor memory span? You've seen us fight in tournaments, so it should come to no surprise to you that we can fly and shoot ki beams...yet you act like you're having cardiac arrest whenever we so much as walk up to you. Nevermind the fact that we inhabit this world with dog and cat people. Hell, the king himself is a freaking dog!"


 * And thus GT is somehow miraculously transitioned into Dragon Ball Online.


 * Vegeta mentions that "A true Sayain's hair never changes" back in Z, yet he grows a mustache.
 * He may have been talking about hair styles. If that was true, then it seems improbable that some Sayains have facial hair (like King Vegeta) while most everyone else doesn't.
 * After fusing with Buu, Uub now has all the powers of Majin Buu, so why can't he heal Goku (who's been blinded by Ice Shenron) if he can at least heal himself? He doesn't even have to restore his energy, just get his eyes back up and functioning.


 * Gainax Ending: The ending, the biggest Headscratcher of 'em all not including the beginning. In retrospect, it's so sudden and bizarre that it's nothing short of a Mind Screw. What happened to Goku in the last 2 episodes? He's clearly dead from that huge energy ball, then suddenly he's alive again somehow able to talk to everybody on earth, then when he's charging the spirit bomb he cannot be killed by Omega at all, despite direct hits (Wasn't that the spirit bomb's weakest point?). We're not even sure if he's dead or Back from the Dead because there's not even a halo to give us any idea (How that is even possible under the circumstances is itself a mystery). Then after the bomb's thrown, he's dead again, apparently brought back to life, then suddenly he just leaves without even saying goodbye. Vegeta knows something's up, then suddenly we see his clothes left on the ground. But in DBZ when they die, they die with their clothes (In fact, that shot is out of sequence and is shown after the end of the next couple of events). But then he's off to visit Roshi and Piccolo, who both also know something's changed about him, but a mere "Are you...?" is not very helpful. When they take their eyes off him for a second, there's suddenly no one there. Then the Dragonballs merge into Goku, then he disappears. Where does he go? Why did he have to go? Was there no other alternative? What happened to him?
 * He doesn't return for 100 years, and if you leave aside what you saw in A Hero's legacy, it's not clear if he's alive or dead. Theories include Ascended to A Higher Plane of Existence or that Goku became Shenron himself. And is he isn't even remotely bothered by the fact that almost everyone he knew is dead.
 * A Hero's legacy was made earlier just after the Baby Saga and they intended Goku to be clearly dead and be the Spirit Advisor to Goku Jr. At that time, no had any idea how GT was going to end or just how they were going to get there, they hoped to stop with Baby Saga. But Executive Meddling (which is why GT even existed) wanted to rush two more sagas in production because producers wanted the series to coincide with the release (and marketing) of Dragon Ball: Final Bout for the Playstation. Viewer ratings began to go into landslide around the Shadow Dragon Saga so they abruptly Cut Short the series and rushed out a hastily written ending out the door. Yes. Seriously.
