'''Basic Trope''': TheHero must fight on his own in the FinalBattle, even though his comrades followed him everywhere before.
* '''Straight''': The TrueCompanions finally reach the BigBad, whom TheHero then engages in one-on-one combat, while his friends idly stand by.
* '''Exaggerated''': TheHero leads a massive army against a lone and isolated BigBad, then challenges him to a duel.
* '''Downplayed''': TheHero's allies help in the final battle...by channeling their combined powers into him.
* '''Justified''':
** Killing the BigBad is something that TheHero [[ThisIsSomethingHesGotToDoHimself has to do himself]] because ItsPersonal.
** Alternately, only the hero can get into or onto the spot where the BigBad plans to hold his last stand.
** Perhaps TheHero and BigBad [[BlastOut are the]] [[EverybodysDeadDave only ones left]].
** Or the BigBad is wearing a special armor that can only be penetrated by a special type of weapon which only the hero possesses.
** Or ConservationOfNinjitsu makes ganging up on the villain pointless or counterproductive.
** Or the other heroes are busy holding off the {{Mooks}}, QuirkyMinibossSquad, or their own [[ArchEnemy Archenemies]], that the BigBad employed so that the Hero and Villain can settle it face to face.
** "It's an Honour thing".
** "I CHALLENGE YOU TO A DUEL!"
** BecauseDestinySaysSo
* '''Inverted''':
** Instead of sending the QuirkyMinibossSquad after him, BigBad faces off against TheHero in person.
** After being alone the entire season, someone's ''finally'' got TheHero's back in the big battle.
* '''Subverted''':
** TheHero challenges the BigBad to a "fair duel", then signals his friends to come [[UnwittingPawn swarming from all directions onto the villain]].
** The Lancer (or another party member) refuses to left his friend fighting on his own, so he rushes to assist him in the battle.
* '''Double Subverted''': But the villain had his QuirkyMinibossSquad nearby, who proceed to keep TheHero's allies busy while their respective bosses duke it out.
* '''Parodied''': As soon as TheHero and the BigBad draw swords, both sides' allies pop their popcorn cans open and sit around in lounge chairs, cheering and commenting on their progress.
* '''Zig Zagged''': It looks like the hero is going to face the villain alone, but wait! His allies managed to [[TheCavalry arrive in time!]]... only to realize the villain and hero are somewhere else. Except for the SixthRanger!... who can't help because TheDragon is keeping him busy.
* '''Averted''': TheHero's TrueCompanions follow him to the FinalBattle and perform at the top of their abilities, each of them contributing equally to their victory.
* '''Enforced''': To reinforce AnAesop that good always triumphs over evil thanks to moral superiority and not due to overwhelming numbers, TheHero must always defeat the bad guys alone (even when they gang up on him).
* '''Lampshaded''': "It's one of his hero things. He has to fight the final bosses one-on-one."
* '''Invoked''': "It seems... [[IncurableCoughOfDeath *cough*]] ...you'll have to... go on alone..."
* '''Exploited''': The BigBad makes himself look honorable so that the hero will insist on engaging him alone, and thus be vulnerable to treachery.
* '''Defied''': TheHero tries to protect his friends by leaving them behind before the final battle but they outsmart him and [[BigDamnHeroes arrive just in time to save his ass]].
* '''Discussed''': "If he has to go on his own, what good were we!?"
* '''Conversed''': "Oh, come on! This guy's been [[CombatPragmatist doing whatever it takes to win]] for the whole series, and suddenly when the time comes to fight the big villain he goes all by himself?"
* '''Deconstructed''':
** The [[TooDumbToLive noble]] hero challenges the villain to a duel and is [[WhyDontYaJustShootHim shot in the back]] by TheDragon.
** Alternately; TheHero becomes disillusioned with his friends after they fail to help him in the most important battle, eventually abandoning them in a fit of resentment.
* '''Reconstructed''':
** The laws of the universe prohibit the epic battles to be won by dirty tricks and the bullet ricochets off TheHero's back.
** Alternately, he had a bulletproof vest on because [[GenreSavvy he knew]] the bad guys would break their word. Which is why TheLancer also followed and engages the Dragon. Plus, the hero isn't doing it (just) for honor. ItsPersonal.
* '''Played For Laughs''': The good guys have a FoodFight to determine who is the strongest to face the BigBad. The latter, meanwhile, grows bored and leaves for another world.
* '''Played For Drama''': The good guys know that whoever ventures to face the BigBad will not return, regardless of the outcome of the actual battle, so everyone tries to secure "the honor" for him-/herself in order to save the others.
