Tensou Sentai Goseiger/WMG

The Zyurangers have helped the Gosei Angels in the creation of the Goseigers.
After defeating Bandora and sealing her away, the Zyurangers ascended to Heaven. After learning about the Gosei Angels' mission to protect Earth, they lent a hand to them in order to create their own Super Sentai team. That's why the Goseigers resemble the Zyurangers so much.

We've actually met a Gosei Angel before.

 * One Damsel in Distress of the week in Dengeki Sentai Changeman was a woman with usually-hidden angel-wings whose singing was so beautiful it instantly took away everyone's will to fight. She has to be from Gosei World.

Gosei Knight will turn out to be...

 * Nozomu?
 * Magis brought back from the dead?
 * A Fusion Dance of the two?
 * Wait... A green ranger down thought to be down for the count or a young boy joins the team as a white(?) ranger with a weapon modelled after an animal head? Where have I seen that before?
 * Gosei Knight is Tommy Oliver, calling it now.
 * Looks pretty well Jossed. Gosei Knight is Groudion itself. Seems the Headder has made some sort of evolutionary leap over the last 10,000 years, thanks to a deal with the planet itself.

Magis would've controlled the Mystic Brother.
My only reason for thinking this, however, is simply because they are both green. By this theory, Mystic GoseiGreat is the true base form.
 * Counter by the fact that an ostrich is a land bird, meaning if the Skick didnt control it, the Landick would. If it was Magis', it would probably have gone to Hyde.
 * Unless the Egg Header is a turtle egg!

Magis would've controlled a turtle/battleship mecha.
My only reason for thinking this, however, is simply because it would have been a Dairanger reference.
 * Doesn't hurt that he's a Seaick.

The final battle will be against a Fusion Dance One-Winged Angel Yuumaju...
...formed from Makuin, Kingon, and Bladoron, and will identify as a Chimera.

Bladoron is really a fallen/renegade Gosei angel.
Hes old, but how old we don't know. And his mouth is strikingly similar to the Goseiger after transformation.
 * Not just the mouth, but his face could belong on a mecha...
 * Bladoran said that Uobōzu of the Nessie gave the Goseigers trouble 10k years ago, Kingon ask how he would know and Bladoran said he was well know. Odd considering none of the other Yuumajuu mention Uobozu,not even crypticly, at all. So only three Yuumajuu know of Uobozu. Two who knew him and one who shouldn't know, yet does.....
 * Well,
 * Not quite yet, read below.
 * If one goes by the standard Elemental Powers, they seem to have tribes devoted to Blow You Away, Making a Splash and Dishing Out Dirt--perhaps if he is a renegade Gosei Angel, he has fire-based powers to go with the idea of a particular fallen angel.

Gosei Green will return sometime after the Yumajuu are defeated.
Either Magis himself will come Back From the Dead, or someone else (like Nozomu) will inherit his Gosei Green power. Each of the villain groups so far corresponds to one of the Gosei Tribes. Warstar is Skyic, since they were invaders from space, and a major part of their arc was the rivalry between Gosei Red and Derepta. The Yumajuu are Landic, because they were originally sealed in the earth. Their appearance marked the debut of Gosei Knight, who was originally the Landic header Groundion. If this pattern continues, then the next group of villains will have a subplot concerning the Seaic tribe, and frankly the idea behind Magis is just too great to only be used for one episode.
 * The end of episode 32 has the Bibi bug nest sinking (or possibly being pulled) under the surface of the sea, so the probability of the next arc having something to do with the ocean or Seaic tribe looks quite high.

The Mystic Gosei Headers are strong because they have the power of Dino Guts.
Why else would they be nicknamed the Abare Header?

Magis is the Big Bad
I don't think it was coincidental that Magis died right at the exact same time where the attack on the Tower of Heaven took place. He faked it so that he may start the attack.
 * So what your saying is somehow Magis was also Derepta while he and Hyde were fighting Kurasunigo? Truly a wild guess.
 * Not exactly, I said to start the attack, I didn't say it was poison to attack it.
 * Jossed.

Bladerun is the Big Bad
Considering he is currently the sole source of Mooks and Make My Monster Grow, they can't very well kill him off anytime soon. After the Yumajuu are defeated he'll go and join the next group of baddies (possibly gaining some yellow highlights to complement the red and blue) and after they are defeated he'll reveal his true form as Bladerun of the Satan and unleash his monsters made from the combined DNA of Warstar, Yumajuu, and .
 * Well, in this case, it would be the DNA from Warstar and the Yumajuu, and the robo, or "R"NA from Matrintis.
 * I actually think this idea makes the most sense of any of them, he's the only one I can think of to make the final battle...however, I have other ideas, see below.

The third group of monsters will be named after action movies
And when (not if but when) Bladerun joins them he'll start calling himself Bladerun of the Die Hard.
 * Somewhat Jossed, as the Mantrintis are named after movies featuring robots, however it's also somewhat comfirmed in that some of the movies they're named after happen to be action movies.

The Groundion Header's original power was Extra Ore Dinary
His Landick origins, gold and silver appearance, and 'Knight Metallic' attack all point to a 'metal' motif. Plus, the traditional idea of a 'knight' is a warrior clad in metal armor.

Shinkenger team-up WMGs

 * Genta will get on Hyde's bad side as soon as he says what he does for a living. (Genta being a Sushi seller would not go well with Hyde being a guardian of the sea...)
 * Would make sense if Hyde was a seaick version of gosei knight.Plus he hasn't attacked any fishermen and it should be noted he was eating lobster tail with the others in one episode.
 * Bladerun could give an Ayakashi a third life, where it grow to a size twice that of any mecha the good guys have.
 * We already saw third life in Shinkenger once. It was, indeed, huge.
 * Takeru holds back his first impression of Alata, after having been wrong about Sousuke previously.
 * A spell turns the Biibi into bug-wing backpacks for the Nanashi.
 * Kinggon's usually foul mood is suppressed by shamisen music
 * Eri starts worshiping Mako while Kotoha turns her attention towards Moune
 * Ryuunosuke gets on GoseiKnight's nerves almost immediately, but Agri and Chiaki hit it off
 * Jii and Prof. Amachi form some kind of buddy-cop-esque parody
 * Juuzo and Dayu cameo in human form
 * Juuzo, yes. Dayu, very very very slim chance, but probably no.
 * Another crossover Super Mode involving the heads of their Origami on the Shinkenger's chests.
 * Let's not forget an epic 5-way battle between the combined Sentai teams, Gedoushu,and all 3 Goseiger villan groups.While the battle will be a stalemate for the villains the heroes will start losing badly.Then out of nowhere the next Sentai team shows up defeats most of the baddie then leaves the rest for the Goseiger & Shinkenger to finish off.
 * The Goseigers initially refuse to acknowledge the Shinkengers on the grounds that they're normal humans and not Gosei Angels, but after learning of Takeru's struggles as a false lord they realize that people don't need to be born special to become heroes.
 * Normal humans?Since when do normal humans fight ghost monsters by writeing magic into the air?The Goseigers appeared in the last Vs movie and knew who the Shinkenger and Go-Onger where,yet didn't even talk to them and where only seen by Daigoyo.
 * The next team of Super Sentai, Kaizoku Sentai Gokaiger, will make an Early-Bird Cameo, similar to Double, the Goseigers, and Ozu.

Bladerun will be back
Otherwise all that build up would have been pointless.
 * Maybe he'll turn out to be the model for Matrintis' foot soldiers or even the true leader/founder of Matrintis aka Buredo-RN of the Replicant. His name would fit better with the Theme Naming used by Matrintis (robot-based movies) than with Warstar (space/extraterrestrial sci-fi) or the Yuumajuu (monster sci-fi)
 * Reportedly, he's coming back as.

The third enemy faction will be modeled after extinct creatures.
It would be an interesting transition: creatures that exist around us => creatures that may not exist => creatures that no longer exist.
 * Seemingly Jossed--the "Matrintis Empire" appear to be modeled after machines. Which means that if Buredoran comes back, he'll probably be some kind of cyborg at the very least. Or maybe he's in Metal-Alice's tablet?

The final battle will feature all three Big Bads combining
Why else would they have three groups except to do something like this?
 * Wouldn't be a bad idea. Worked with the two Ulimate Orgs in Gaoranger.
 * Seems to be Jossed with  as the Big Bad

Gosei Green will be the Seventh Ranger.
We just know they're not through with Gosei Green. I see two ways for this to happen, A) Magis returns from the dead somehow. Or B) when the Goseiger on on the ropes, his spirit transfers his powers to an ally of the Goseiger to take his place.
 * They are through with him.Toei is known for haveing past actors have cameos in later sentai series usually wearing the same colors they wore when in the series they stared in.Also they've definatly been on the ropes with Mons-Drake nearly blowing up the planet(twice) and Makuin and Kinggon almost turning the earth into a polluted wasteland.Yet no Gosei Green.

Bladerun will ultimately join the Goseigers in the final battle
Think about it, he's been on every side except theirs so far, he's on whoever's side is left to join. It'd make sense if after the final faction falls, he'd join them. Or if the Fallen Hero theory above is true, he'll be brought back to the good side somehow.
 * Highly unlikely, as Bladerun

Bladerun is actually part of the villains for Gokaiger.
True name being "Bladerun of the Characteristic", with the power to take on the motif of any previous enemy faction.
 * Jossed, he's

Sky-Land-Sea Strike really is a suicide attack.
It's not how it was used, it really did do what it was supposed to do. That's why we've never seen Sky-Land-Sea Gosei Great in the show before.
 * Jossed, the 199 heroes movie shows that Gosei Great and the Seaick Headers are still alive and kicking.
 * Which is surprising, because apparently most of the mecha were destroyed off screen in the Legend War - the Goseigers must've gotten lucky.
 * Gosei Great was seen downed at the start of the movie... looks like it was only damaged and was repaired. Datas doesn't appear in the 199 Heroes movie, so we can guess what happened to him... maybe they weren't so lucky after all.

The Exotic Brothers and Mystic Brother' names were mixed up during production.
That's just common sense, I guess. There's nothing mystic about the Mystic Runner, ostrich can however be called an exotic bird. As for the Exotic Brothers, well, they only shows up once in the entire series, in a time of great need, with no explanation for their existence; I'd call that mystic.

The Goseigers were set up as foils for the Gokaiger from the beginning.
By the time Goseiger started, Toei had already tested the waters with Kamen Rider Decade was over: they knew what did and did not work. 2011 being the 35th anniversary of Sentai, they must have come up with a basic storyline for Gokaiger by that point (late 2009–early 2010), i.e. the fact that this would be a team of Anti-Hero who would slowly learn what it means to be a Sentai team. Because of the tradition haivng a team-up movie, this decision must have impacted the production of Goseiger: namely the Goseigers were designed to be everything the Gokaiger would not be: selfless, humble, friends to all children, and determined to protect the Earth, so that when they meet the Gokaigers, they would butt heads with each other.
