'''Basic Trope''': The story begins with someone who's not the actual protagonist; he'll be coming in later.
* '''Straight''': In the HumongousMecha anime ''Trope Busters'', the story revolves around [[HotBlooded Bash]] the pilot of the eponymous mecha, and his fight against [[BigBad Emperor Evulz]]' [[TheEmpire evil empire]]. However, in episode 5, Bash makes a HeroicSacrifice to stop TheDragon Triskelatus. From episode 6 onward, the pilot and the center of the story is [[IronWoobie Bob]], Bash's adopted little brother.
* '''Exaggerated''':
** Something like this happens so often in ''Trope Busters'' that by the time the 24-episodes anime ends, the titular mecha has been piloted by a dozen or so pilots, some of them not even lasting ''half an episode''. But each of them is a protagonist of their own story arc.
** The entire group of heroes at the beginning gets brutally wiped out all at once and is immediately replaced by another group of heroes.
* '''Downplayed:'''
** ''Trope Busters'' is TheAnimeOfTheGame - in the game, you control five characters. However, one of them is a GuestStarPartyMember and is replaced later on with another more significant character.
** Halfway through the first season, Bash is PutOnABus and replaced by Bob.
** Bash starts out as the leader, holds an important role throughout the show, and avoids being killed at any point, but as the series goes on it becomes clear that Bob is the true protagonist as he grows as a person and takes over from Bash.
** The series marketing focuses on Bob to make clear that he'll be the protagonist, even though the early chapters are focused on Bash.
* '''Justified''':
** The HumongousMecha is some kind of ArtifactOfDeath. [[Manga/{{Bokurano}} It demands the sacrifice of its pilot's life force.]]
** The fight against Emperor Evulz' empire ''really'' takes its toll.
* '''Inverted''':
** ChekhovsGunman
** The first few episodes of ''Trope Busters'' focus on Bash, despite the marketing focusing on his little brother Bob, who is introduced later and then becomes the focus of the show. However, in one of the final episodes Bob suddenly gets killed off and Bash has to avenge him in the finale.
** It seems that Emperor Evulz is the BigBad for Bash to fight, but in episode 6 he is replaced by the his BastardUnderstudy Triskelatus. [[DarkerAndEdgier The tone of the anime changes considerably]] [[KnightOfCerebus after Triskelatus become the new emperor]].
* '''Subverted''': In episode 17, Bash is BackFromTheDead and is now ready to pilot the Trope Busters again. The story again revolves around him and his much-surprised friends and foes.
* '''Double Subverted''': But at the end of episode 17, he makes a HeroicSacrifice. ''Again''. [[DecoyProtagonist This is after the viewers believe that the story will continue to revolve around Bash]].
* '''Parodied''': Bash is a traditional cape-wearing, charismatic hero who is first seen delivering a speech to his fellow pilots about the importance of bravery and teamwork... right before being gunned down by a bunch of {{Mooks}} less than five minutes into the first episode.
* '''Zig-Zagged''': Bash dies at the hand of Triskelatus, but some episodes after that we see that Bash is alive and kicking the arses of TheEmpire. It seems that Bash is still alive after all, just not fighting alongside Bob. But then it's revealed that those episodes are about Bash's past. But in one of those episodes, we see adult Bob fighting alongside Bash. The episode right after that we see the very same adult Bob visiting the worn-out grave of Bash...
* '''Averted''': Either Bash or Bob is the protagonist of ''Trope Busters'', from the first episode to the last.
* '''Enforced''':
** "We want to make a coming of age story of Bob. Bash's death give the audience a sense of passage of time."
** Bash is in there for WolverinePublicity, but the writers still want to make him integral to the plot in some way.
** The futility of war is the story's {{Aesop}}.
** [[NoBudget The creators couldn't afford Bash's voice actor for more than four episodes]] and [[TypeCasting he can only do hero characters]].
* '''Lampshaded''': "Bash kicks the bucket and you all assume I'm best for the job? You're out of your minds! Bash is the only one any good at this sort of thing!"
* '''Invoked''': "You are now the leader of LaResistance, Bob. It's your story, not Bash's."
* '''Exploited''': Bash trained Bob ahead of time, knowing that, eventually, he'd get himself killed, and didn't want to leave without knowing someone could continue his legacy.
* '''Defied''': Bash makes a HeroicSacrifice... but comes back at the end of the episode, having been OnlyMostlyDead.
* '''Discussed''': "You know, I really thought Bash was the one who would lead us to victory..."
* '''Conversed''': "Wait, Bash's not TheHero?!"
* '''Deconstructed''':
** LaResistance have a hard time coping with Bash' death.
** [[ReplacementScrappy The audience doesn't like Bob]].
** Bob struggles to function due to SurvivorGuilt, feeling that it's not fair that Bash will never be remembered as a hero and he will usurp his place just because of the coincidence that Bash died first.
* '''Reconstructed''':
** SacrificialLion.
** Bob does his best to surpass Bash in every way, and he succeeds.
** [[TookALevelInJerkass The uglier parts of Bash's character]] are revealed as he gets closer to death, so the audience is more accepting of his demise and Bob's rise.
