Determinator/Western Animation

"Rainbow Dash: Today I learned what the most important quality really is; a certain kind of spirit; a stick-to-it effort. A never-give-up, can-do attitude that's the mark of a real winner! And this tortoise has it! Twilight Sparkle: Tenacity!"

- "May The Best Pet Win", My Little Pony Friendship Is Magic

"Starfire: They are too numerous to fight! What shall we do? Robin: Fight anyway!"
 * Robin, especially in situations where he takes a Batman-esque Badass Normal Leader role on a team; for instance, Teen Titans:

"Zuko: "My father says [Azula] was Born Lucky. He says I was lucky to be born. I don't need luck though; I don't want it. I've always had to struggle and fight and that's made me strong. It's made me who I am.""
 * This goes double for anything involving Slade.
 * Prince Zuko from Avatar: The Last Airbender. Even before he knows that the Avatar is alive, he sails around the entire world looking for him. He then chases him from the South Pole to the North, surviving at least one assassination attempt as well as several duels, infiltrates two heavily-protected fortresses on the way, defeats a master firebender and battles with a master waterbender, and is only defeated when a blizzard prevents him from moving too quickly. He gets into about two dozen fights during that time... and that's just the first season. Sokka's opinion is that "if we know one thing, it's that Zuko never, ever gives up," but Zuko's statement is rather more poetic.

"Ursa: "That's who you are Zuko. Someone who keeps fighting even though it's hard.""
 * His flashback in "Zuko Alone" shows just what the above line is all about. He was no prodigy like his little sister Azula, so his daddy Ozai paid him virtually no mind and his little sister Azula laughed at his every misfortune even then. However, he always strove to improve his abilities and to prove himself to everyone. His mother recognized this, as shown by the following line, which came after the example in the flashback:

"Katara: "I will never, EVER turn my back on people who need me!""
 * To a slightly lesser extent, Katara. Want to learn waterbending? Just a quick trip to the other side of the world. Your new friend's in prison? Okay, get yourself arrested and break him out. The local waterbending master won't teach girls? It's cool, just practice in secret, challenge him to a fight, and proceed to master the element faster than the Avatar. Want to help that repressed village? No problem, just disguise yourself as a minor deity and destroy a polluting factory. Oh, and about those guys who killed your mom... Not to mention several times she is all that's holding the team together, most notably in "The Desert". In her own words:

": You still try to fight? * tosses him thirty feet* Can't you see that it's hopeless? Superman: * gives him a flying punch, then a right hook, and pins against the wall by the throat, one-handed* That man won't quit as long as he can still draw breath. None of my teammates will."
 * Fire Lord Ozai also has shades of this. It does not matter how freakishly powerful the Avatar is, the man simply will not admit defeat.
 * Optimus Prime of Transformers is this trope, with Megatron coming in a close second.
 * This is a pretty regular thing for Starscream. In Transformers Generation 1 he tried to take over the Decepticons at every possible occasion--even after he died and came back as a ghost.
 * Dinobot from Beast Wars almost never willingly runs from a fight. This reaches its climax in 'Code of Hero', when . Depth Charge also fits this trope, as his persistence to find and destroy Rampage leads to him putting that mission above all else, including stopping Megatron from destroying the Autobots and changing the universe as we know it. Really, Depth Charge needs to get his priorities straight. By the end of it, he was on board to stop Megatron. Unfortunately, at that time, Rampage was sent out to stop him.
 * In Cybertron, Starscream was so much of a Determinator that he managed to use Heroic Resolve in a way that's usually reserved for... well, the heroic. At one point, he took on the combined might of the entire Autobot team to get the MacGuffin,
 * In Transformers Animated Starscream kept trying to kill Megatron
 * Waspinator becomes this in Transformers: Animated, determined to get revenge on Bumblebee, he'll  to get the justice he thinks he deserves.
 * Kyle in South Park is this frequently, almost always in an attempt to thwart Cartman's latest scheme.
 * Dib of Invader Zim is a Determinator well past the point of insanity, considering Failure Is the Only Option and he's surrounded by Bats. Zim is a similar case, continuing his "mission" even after being exiled due to his entire species loathing his very existence, although there's disagreement as to whether he merely ignores their scorn or he really is that stupid.
 * Riley from The Boondocks. He's not a very good fighter, but he's able to take a lot of punishment before going down.
 * In the Season Finale of Justice League Unlimited, with no time to come up with a better plan, Batman keeps on coming after  with nothing more than his fists, feet, and utility belt, relentless even though the other tosses him away casually. After the last such attempt, irritation is evident.

"Dr. Destiny: But you're different. You don't have any special powers. Batman: Oh, I have one, Johnny. I never give up."
 * Batman also provided a page quote for the main Determinator article:

": You can't win. Shining Knight: I'll die as befits a knight: Defending the weak!"
 * Just ... Batman. Period.
 * Earlier in the series was another example. Shining Knight, an embodiment of the Knight in Shining Armor trope, was fighting and refused to give in no matter how badly he was beaten.

"Superman:You fought a good fight, stay down! Captain Atom: ...I can't do that, Superman. (rushes him) Superman:(dodges his attacks and punches Captain Atom into the wall)"
 * Then there's Wonder Woman in the adaption of For the Man Who Has Everything. She absolutely gets the shit beat out of her by Mongul for almost the entire episode and refuses to stay down even though each hit she takes brings her closer and closer to death. She shows that you CAN be on the receiving end of a total Curb Stomp Battle and still look Badass.
 * Don't forget Captain Atom in Flashpoint. He gets a horrible ass whooping by Superman when trying to keep . Though Supes is perfectly fine at the end of the Battle, Cap is beaten so badly his suit cracks and he's barely able to walk, much less throw a punch. And yet he still keeps coming until he's completely unconscious.

"Tigress: If he's smart, he won't come back up those stairs. Monkey: But he will. Viper: He's not going to quit, is he?"
 * Considering the fact he stayed locked up in prison for twenty years and, upon escaping, was just as intent on becoming the Dragon Warrior as ever, I'd say Tai Lung from Kung Fu Panda qualifies. As does Po himself. Even when Shifu does his best to make Po quit, Po never does. While Po is in the middle of rolling down the mountain due to a kick from Shifu, the other student have the following conversation about it.

"Darla: I didn't get where I am today By letting myself get pushed around! And no man nor beast or kittycat or doggy Is goin' to drag me down!"''"
 * Darla Dimple from Cats Don't Dance, while not physically intimidating, is still a Little Miss Badass who refuses to allow anyone to interfere with her films, to the point of constructing an Evil Plan to discredit them, and (almost) suicidal attacks on their shows.

"Phoebe: C'mon, Arnold, let him go. It's just an egg. Arnold: But it's Dr. Skeledon's egg. And it's up to me to get it back to her!"
 * Also, Danny. Despite all of the hardships and prejudice he goes through, he still doesn't give up on his dream of being famous.
 * Captain Clown from Batman: The Animated Series, who takes a ridiculous amount of crowbar shots to the head.
 * Well, he was a robot.
 * The eponymous character of Kiwi.
 * "The Busasaurus" episode of The Magic School Bus showed Arnold's Determinator side.

"Chris: Dad...I want to quit the Boy Scouts. Peter: Chris, you're a Griffin! And the Griffins never quit! Cut to scene in hospital. Peter is in surgical scrubs and holding defibrillator paddles. Peter: Clear. * poomp* Clear. * poomp* Patient: Thanks, doc, you saved my life! Peter: Clear. * poomp*"
 * This episode also ended with Arnold fighting off a T.Rex to protect the class and get the egg back.
 * Parodied, like many other things, in an episode of Family Guy.

"Bart: Oh my god. He's like some sort of... none... giving-up... school guy!"
 * Another example comes from Carol Channing, of all people. During her celebrity boxing match with Mike Tyson, she just WOULD NOT go down.
 * Courage the Cowardly Dog will brave any danger and take any punishment to save Muriel. His best example of sheer determination didn't even involve saving her. After getting beaten to a ridiculous pulp by Mecha-courage repeatedly, he just keeps getting up, eventually shorting out the robots batteries through sheer persistence.
 * Apu Nahasapeemapetillion thinks that the town of Springfield should hire more police officers. In one episode, he mentions that he'd been shot by armed robbers 8 times already this year. As a result, he almost missed work. Almost.
 * When Bart was playing hooky, he destroyed a wooden bridge to stop Principal Skinner from following him. Skinner simply walks into the river, momentarily emerging at the other side.

"Rasslor: This is unbelievable! I could crush your body, I could smash your bones, but I could never break your spirit!"
 * Wile E. Coyote, Sylvester, Elmer Fudd, Yosemite Sam, and Marvin The Martian of Looney Tunes.
 * No mention of Daffy? He'll do whatever it takes to upstage his rival.
 * Tom of Tom and Jerry.
 * Plankton of SpongeBob SquarePants.
 * Spongebob may be a pushover most of the time, but nothing will stop him doing his duty for the Krusty Krab, whether it's delivering a pizza or saving his boss from execution.
 * Russel of the Gorillaz is swimming to Plastic Beach, and he doesn't look happy. Not to mention Noodle who, depending on which story is true, may have just
 * Bender of Futurama, who, while missing a leg and both his arms, crawls with his eyes to save his friends.
 * In Wakfu, Nox is so much of a Well-Intentioned Extremist, he's been artificially extending his lifespan for centuries in order to continue pursuing his goals.
 * In DuckTales, El Captain was so determined to get the Treasure of the Golden Suns he managed to live four hundred years just because of that.
 * Finn of Adventure Time is a good example. In one episode, he actually runs on broken legs (!) to save the candy people.
 * Monkey in the Dexter's Laboratory 'Dial M For Monkey' short series. Most notable in one episode where Monkey fights against intergalatic wrestling champion Rasslor, and gets his ass handed to him over, and over, and over, and over, and over, and over...until Rasslor finally throws the match out of respect for Monkey's inability to stay the hell down.

"Tunar: "I'll follow ya straight to the flamin' pits of Magmel before I give you up!""
 * Phineas and Ferb never give up on their attempts to do the impossible. Also, Candace, Isabella and Doofenshmirz qualify
 * Finding Nemo: "I didn't come this far to be breakfast!"
 * Total Drama Island gives us Ezekiel, who, after being kicked off first once more in the third season, managed to get back in the plane four times after Chris tried to get rid of him, eventually becoming some sort of zombie. All to prove he was worthy of winning the season.
 * In the Spider Man 1967 episode, "The Sinister Prime Minister," Spidey is the only one who knows that a foreign Prime Minister has been abducted by a impostor and must strike again and again in order to rescue him.
 * In ThunderCats (2011)
 * "Ramlak Rising" introduces fishman Captain Tunar, who persues his Planimal Nemesis the Ramlak with the zeal that comes from putting Revenge Before Reason.

"The Swordmaker: You don't give up easily, do you?"
 * Series' Hero Lion-O also has this quality, though to a more benificent end. In "The Duelist and the Drifter," after suffering defeat in a duel with a predatory Master Swordsman, Lion-O heads to a forge and stubbornly insists that he'll make a sword that can withstand a rematch, no matter how many attempts it takes, despite having no training in swordsmithery. A retired swordmaker is so amused by Lion-O's determination that he hangs a lampshade on it, and offers to lend a hand.

"Kaynar: You're like a toy that never breaks, I LOVE IT!"
 * Even the villains notice it:


 * Hey Arnold: Brainy has been given OffhandBackhands whenever he tries to be near Helga since the age of three… He now has nine, and he still does it.
 * The six main ponies from My Little Pony Friendship Is Magic are each considerably persistent characters, and the value of perseverance is a common theme throughout the series.
 * Applejack is a surprising deconstruction, though, in that in the fourth episode of the first season she is used to demonstrate that persistence can be a bad thing if one is overly persistent in trying to do something when surrounded by evidence that it cannot be done; in that case, trying to pick all the apples in the orchard herself and becoming sleep-deprived in the process. Of course, this is presented in the context of being compared to doing something else that would achieve the same thing more practically; namely, accepting help from friends in picking the apples.
 * The Cutie Mark Crusaders. Sweet Celestia and Luna both, the Cutie Mark Crusaders. "And we will never stop the journey, not until we have our Cutie Marks."
 * The tortoise from "May The Best Pet Win" takes this arguably even further; taking part in every competition even after losing each previous one, and never giving up on winning over Rainbow Dash's approval even as she keeps putting him down.
 * Saint Walker from Green Lantern the Animated Series. Climbs a mountain in search of a savior to battle the Red Lanterns, and when he reaches the top . Instead of giving up, he keeps hope and vows to find a way to battle the Red Lanterns,
 * Mr. Bogus would also qualify for this trope. Despite the fact that he is only a few inches tall, nothing will stop him from fixing a problem that has arose in either Tommy's house or in Bogusland.
