- Zuko from Embers. The GAang assumes that getting blasted off a mountain killed him simply because he did not show up the next day to snarl at them.
- Xander in The Journeyverse. One particular example is in Fallen Angel when he keeps getting up to fight Glory (a hellgod) and almost kills himself defeating her.
- Dragan from the same fight.
- Ga'ri in the early parts of Big Sister, still trying to recover from the Gadget Drone incident mentioned in StrikerS carries a baby across a volcanic Death World with what little power she has left, crippling herself again in the process, then manages to fight off a lethal infection and regain use of both her legs and her magic, this time without the help of high-Magitek rehabilitation facilities.
- The Five-Man Band and the Big Bad and his Dragon in Children of Time: the (Tenth) Doctor, Sherlock Holmes, Dr. Watson, Beth Lestrade, Sally Sparrow, the TARDIS, Professor Moriarty, and Colonel Moran.
- It should be noted that, while though some of the heroes make Deals with the Devil, they still do so to protect loved ones at all costs.
- The TARDIS comes across as very stubborn and mother hen-ishly protective of her Time Lord and his Companions.
- Moriarty is unbelievably determined to survive at any cost...
- Moran spends several months hunting a seventeen-year-old girl. Considering that he spent over two years hunting Holmes, however, the surprise is not that he kept up the hunt but that the hunt kept him up.
- Littlepip from Fallout: Equestria:
I would fight to to make that bright and innocent past our future again. Even if it means dashing myself against the evil and cruelty of this wasteland until there is nothing left of me. And then, when I am too broken to go on, I will float my dying body right down into the throat of the darkness and make it choke on me.Or, you know, this could all end in sunshine and rainbows. No need to get pessimistic.
- In A Hero, Dalek Sec describes the Last Great Time War thus to Homura: On one side, The Time Lords, undisputable masters of the universe and the most experienced Temporal Power there is. On the other, the Daleks, a race born in a world torn apart by war and with a technology that was woefully behind that of the Time Lords. The only thing going for the pepperpots? Sheer, bloody-minded determination.
- Hybrid Theory. Determination is sufficiently central to the magical system and core plot that little can be said without spoiling the whole thing, except for "Holy crap!" and "Did you just punch out <censored>?"
- In Code Geass: Mao of the Deliverance, Mao definitely qualifies. He gambles, blackmails, steals, does drugs, flies through a frickin hurricane, takes on soldiers and terrorists and gets shot repeatedly all in his quest to save C.C. and be with her forever.
- Deconstructed in All You Need Is Love:
Matsuda (throwing himself against a door, repeatedly): You know… Duck… I don't think this is working…Duck: I'm sure you'll get it eventually. The trick is to keep trying and to believe in yourself, then any task can be accomplished. Or so public educational television tells me.
- In the climax of Fever Dreams Light holds the Death Note in the fire until it burns to ash even though his hands are burning along with it.
- Light and Misa in Gods Of This New World but especially Misa, who gets up and keeps fighting after she's been stabbed in the chest with a sword.
- Takato , OH DEAR LORD TAKATO. If continuing to fight againgst a hoard of Mega level digimon. despite the fact that your clothes are literaly soaked in your own blood, and you are almost paralysed from your brain cells dying doesn't count as this, nothing does.
Takeru: "Daemon is an extremely powerful foe, and his power has increased in the past fifteen years. His anger and desire for vengeance makes him practically invincible, a berserk fighter who will do anything to win."Takato: "But…my friends will never give up! Rika will never give up!"Takeru: "Neither will he."
- Daemon as well.
- In Dragon Age: The Crown Of Thorns, the Wise Prince protagonist keeps on going and pulling one plan after another, even though the fact he grew up in a Deadly Decadent Court could have long ago turned him into a self-centered cynic. He also displayed a high physical resilience in the deep roads, up until he stumbled upon a certain someone else and finally decided to allow himself to faint after two days of no sleep, fighting, getting repeatedly injured, tried for fratricide that never happened, dragged through streets in chains, spat on and generally not having a very nice time.
- In The Odyssey, this Ulyssian's defining trope; he is forever striving to equal and surpass his more powerful classmates, who are all Dragon-Blooded. It's a rather grim interpretation of the trope.
- In the Firefly fic Forward, Mal shows his canon tendencies, but on top of that there's Book, who pulls a You Shall Not Pass when defending River from Reavers. As the story progresses, River herself becomes one as well, up to the "Fourth Interlude" chapter, where little things like a bunch of cracked ribs or having a leg broken, getting shot in the stomach, and getting a concussion from a ricocheting bullet don't stop her from kicking ass.
- Harry James Potter Evans Verres of Harry Potter and the Methods of Rationality becomes this in chapter 89 after Hermione gets killed by the troll. It's not good news for the safety of the universe.
- Major Shane t. Doran, from Article 2. When completely surrounded, wounded, and telekinetically pinned to the ground by Luna, he still struggles. It takes a knockout spell to subdue the man.
- Greg, the protagonist of the recursive fanfic Friendship Is Optimal: Always Say No doesn't even seem to know the meaning of the phrase "give up", given how determined he is. Even being blown up won't stop him from trying.
- Jericho has the eponymous narrator, Jericho, a stallion from the nation of Teutschland. He appears to be this, since he walked to Equestria, where the story begins, all the way from his homeland of Teutschland, which is across the world and several oceans from Equestria.
According to him in the summary: "Still, with enough wit, some Prussian ingenuity, a droll sense of humor, and wanton murder, I might just survive this. Then again, when you’re going up against an unending list of things like government conspiracies, that guardian angel who keeps telling you to kill people, psycho Equestrian girls with allophilia, a lunatic princess, the legions of the Inferno, the Equestrian culture itself, swashbuckling sword fights, and laissez-faire economists, you begin to realize why there’s a big “if” in the middle of your life."
- The Party Never Ended has the poor addle-sounding Derpy Hooves determined to fight the supernatural storm, no matter what. And the climax features a Battle in the Center of the Mind. In one corner, the entity that drove Luna into Nightmare Moon via Break the Cutie. In the other, Pinkie Pie with Twilight Sparkle helping. Then Rainbow Dash with Pinkie Pie helping. Then Pinkie Pie by herself. Break The Breaker Of Cuties, anypony?
- In the Pony POV Series, the Mane Cast and their Sixth Ranger Trixie stop at nothing to defeat Nightmare Whisper, Fluttershy's Superpowered Evil Side, and save her from herself. By the end of the battle, Pinkie Pie and Applejack are severely cut up by glass (Pinkie Pie from being throw out of a glass window and Applejack from having glass daggers embedded in her back), Twilight and Rainbow Dash have both been sent dangerously close to the Despair Event Horizon, and Trixie has been electrocuted and broken one or more ribs. But the one who takes the cake is Rarity, who has her legs broken and keeps herself in the fight by moving her legs with telekinesis! And then Fluttercruel fights her way out of a Jury of the Damned, getting pretty much mauled by demonic creatures, to get back to help save Fluttershy. She then proceeds to tear the tubes connecting her to Nightmare Whisper out 'by hand, despite the agonizing pain it causes.
- This is actually a distinct plot point from a "side story" (Alternate Universe, but declared part of the POV multiverse by Word of God). An alternate Discord notes that the Ponies of the "Reharmonized" timeline, "Would never give up, no matter how hopeless the situation."
- Also happens with Queen Cadence in the Dark World Timeline. She promised Twilight Tragedy she'd redeem her, but was vaporized before she could. Five hundred years later, her spirit appears to Twilight when she's suffering a Villainous BSOD and helps guide her back to the light, just like she promised.
- Dark World!Derpy. To put this in perspective, she endured 1000 years of living Hell so Discord would remove the curse from Dinky. She marched around Discord's palace, assaulted constantly by crows trying to eat Dinky, and according to Dinky herself, she never let them touch her]]. And she did this with crippled wings and legs''. Is it any wonder at all she becomes an Element of Loyalty? After she's healed by the redeemed six and Dinky is restored, this determination extends to protecting her new friends.
- Sunset Shimmer, from Seven Days In Sunny June, is willing to face down date rape gangs, nightmarish unicorns and a death threat from Princess Celestia if it means saving those she loves.
- In Just Before The Dawn, this is one of Tercio's defining characteristics, and what brings him to Celestia's attention. No magic, super strength, or flight, just determination and willpower.
- Naruto in The Sealed Kunai. While fighting Hidan and Kakuzu, he holds Kakuzu inside his barrier trap jutsu for one full minute while being sympathetically mutilated by Hidan, who is specifically trying to break his handseal. It eventually lapses when Hidan actually stabs through his hand, but enough time was bought for help to arrive.
- In Vapors, in addition to the canonical examples, Aiko is repeatedly held up as an example. Due to her high intelligence and maturity, her apprenticeship instead of being on a genin team, and her past successes, Aiko has been unintentionally conditioned to soldier on through horrible circumstances in pursuit of her goal without asking for help. During her time infiltrating Root she nearly has several breakdowns due to the workload and emotional toll, but continues developing her plan alone for months. Then a new development means that she needs to end things right now, at which point she recruits Sai to help and finishes things in less than a day.
- A Crown Of Stars:
- Before the beginning the story Shinji had stopped hoping for him and Asuka getting together, but he never stopped wanting. His perseverance finally paid off.
- After being told by his wife that she will not forgive him unless their children and Asuka forgive him first, Gendo is determined to earn their forgiveness, not matter what. Even if it seems all but imposible he is determined to do whatever that it takes, and he is willing endure anything.
- Advice And Trust: Rei. Asuka compares her with a Terminator because she never stops. Her finest showing in the battle against Zeruel is actually an example of her Character Development, where she fights her hardest to defend her friends rather than lack of regard for her own life, never gives up and thanks to her resolute attitude she manages killing it in spite of horrible odds.
- Evangelion 303:
- When Asuka ran away, Shinji finally gave up on her? No way! He searched and found a lead, drove one whole day –even though he had no reasons to think that she would remain in one place for so long-, and despite of her stubborn refusals to return, he proposed her.
- Deconstructed with Rei. During a practice she entered a bad flat spin, and she ejected too low because she refused giving up. She got brain damage because of it.
- Thousand Shinji: One of the key components of Shinji's ideology in this story is keeping hoping and never -ever- giving up. He also instills that way of thinking into Asuka (who refuses to give up and stop fighting, hence she does not try to kill herself during her fall into despair as in canon) and Rei (who endeavours to endure, not matter what).
- During the climax, Misato dies and he loses hope for first time. Then Asuka gets killed and he gets broken. When Rei comes along and tells she can bring them back, Shinji regains hope and he remember that he never, ever, quits. And if he has to storm the Afterlife to rescue Asuka and Misato, he will do so.
- The Power Rangers GPX turn this into a motto, declaring that they will never quit, surrender, or lose.
- Whenever somebody encounters a Cofagrigus in Pokemon Black & White: Tale of a Legend, they're in for a long chase and a tough battle.
- Ruby in the Gorn-laiden Blood Rose becomes one of these - of note is the end of chapter 22, where despite having lost both her legs and had most of the skin on her body burned off by an incendiary barrier, she starts crawling off to escape before her Healing Factor even begins to kick in.
- Sherlock Holmes, Dr. Watson, and Davy Wiggins in the Deliver Us From Evil Series:
[Holmes] would have died for a secret. But he will live now, for a friend.Watson: "Porlock, there is no use in arguing the point. I shall search for Holmes. Whether you help me or not is your choice, but you shan't stop me — you have my word on that."Wiggins: "Mum, I've been running that risk ever since I was a mite. I can't tell you what I'm doing, but I need to see it through. Peter's a fine young man, and he'll take good care of you. I'll come back if I can, I promise."
- Fairly English Story: To the point where it's considered being a pussy if you react to a wound with anything more than casting Dia.
- In By the Fire's Light, no matter how grim it gets, Detective Carl Rourke and Mira Grolinsky never give up in their quest to stop the Slender Man.
- Optimus and Starscream in Hate the Dark, but mostly Optimus.
- Eugenesis has Galvatron. Imprisoned, damaged and implanted with technology designed to prevent him from transforming ever again, Galvatron still manages to break free, and more importantly, transform, utterly ignoring the fact that the pain and strain of doing so hurts more than anything he's ever experienced.
