By the end of Last Order, however, he's somewhat received his comeuppance, as after cloning himself so many times that more than one Nova would pop up for every one killed, he's finally put in indefinite cryogenic stasis so that his death doesn't cause any more Nova clones to pop up.
He walks away from series 1 without paying for any of the thousands of lives he consumes - including the protagonist's adoptive father - and series 2 seems set to make him even more sadistic, more amoral, more manipulative, more powerful and much more immortal than before. Professor Desty Nova in Battle Angel Alita has his hands on the controls to the Laser-Guided Karma machinery, almost literally.Yujiro doesnt do that- when his HP hits 0, he instead laughs and walks away. Everyone else, when defeated, is knocked out (or killed gruesomely if they were an early villain and a Secret move was used by any Hokuto or Nanto user). Best exemplified when Yujiro appears as a Guest Fighter in the official mobile game for Fist of the North Star.Well, he is not beaten, but he is humbled enough to hand over the title "World's Strongest Creature" to Baki. At first it seems Baki is winning, even causing Yujiro to bleed, but Yujiro gets serious and begins no selling all of Bakis attacks, eventually beating him. Baki, now the second strongest man alive, attempts to fight Yujiro for the final time. Yujiro is so powerful, even at the very end of the series he still hasn't been defeated. Though several characters have evolved based on his almost unachievable status. To date, nothing has even given him cause to pause. In the one anime fight where someone even lands a worthwhile attack (Doppo counters with several chest crushing punches), Yujiro simply stands up smiling as if he had an itch. When she finally loses, though, she suffers just as badly. She appears, instantly frightens the big bad and begins curbstomping established characters. Dinoponera from Arachnid is certainly one.Contrast Invincible Hero, their Good Counterpart, and Harmless Villain, their opposite in terms of threat level.
Compare As Long as There is Evil (where evil is vincible, but no victory can be permanent in-universe), Joker Immunity (where no victory can be permanent out of universe), and Hopeless Boss Fight, in which a video game player is faced with an ( allegedly) unwinnable fight and has to lose in order to continue the game. The Subverted Trope is Not So Invincible After All, where taking on an apparent Invincible Villain directly turns out to be unexpectedly worthwhile. Stories that abuse this trope have a high risk of Too Bleak, Stopped Caring. The Villain Protagonist is especially at risk to this. If taken to extremes, when the story is entirely about the villain constantly winning in some contrived way, this trope turns into Villain Sue. Tropes Are Tools, and it's perfectly possible to write a good, satisfying story with an Invincible Villain ( Evil Is Cool, after all, and the idea that you can't always deal with evil by punching it into submission is an ancient Hard Truth Aesop), but there are plenty of ways to mishandle them. Meanwhile, a Prevent the War plot gains extra menace if the other guys you're trying not to pick a fight with are both unpleasant and undefeatable. War Is Hell: War is considerably less defensible as a concept if there's no realistic way for you to win, making this trope useful if you want to drive home how awful war is.Tragedy: One easy way for a protagonist's Fatal Flaw to destroy them is for them to get into a fight they really, really shouldn't have picked.Similarly, Film Noir's cynical attitude towards the law means the protagonists will often run into one of these, whether they be The Don, a Corrupt Politician, or a senior and well-connected Dirty Cop.
Crime Fiction: If the criminals are the heroes and law enforcement are the villains, then it's generally unlikely that our protagonists are going to take down an entire criminal justice system.Cosmic Horror Story: The protagonists' insignificance and helplessness in the face of the Powers That Be is the whole point.
