'''Basic Trope''': A character is fighting monsters but eventually becomes one.
* '''Straight''': John, one of the lead survivors of the ZombieApocalypse, is turned into a zombie.
* '''Exaggerated''':
** John, the [[ActionSurvivor last]] [[LastOfHisKind survivor]] of the ZombieApocalypse, [[DownerEnding is turned into a zombie at the end of the movie]].
** Instead of bites or viruses, the disease spreads via bloodshed. Fighting the zombies is the only way to [[SheatheYourSword get infected]]. Running from or even [[JustIgnoreIt ignoring the zombies]] let you live.
** Every single person that the [[WeaponizedCamera camera ]] focuses on instantly turns into a zombie. The cameraman is the main antagonist.
* '''Downplayed''':
** John stands up to the school bullies but ends up joining their gang in the third act.
** John only arises as a zombie after he dies from his wounds.
** John becomes a FriendlyZombie thanks to either HeroicWillpower or a partially successfully antidote.
** There are [[LiteralSplitPersonality several Johns]] and one of them becomes the zombie that another John fights.
* '''Justified''':
** John surrendered himself to the zombies after having reached his DespairEventHorizon.
** John [[HeroicSacrifice sacrificed himself]] so that the other survivors could escape.
** [[OurDemonsAreDifferent Demons]] are born of those who have [[OneManArmy personally killed many powerful foes]]. Every kill of a demon brought John closer to becoming one himself.
* '''Inverted''':
** TomatoInTheMirror.
** One of the zombies is injected with the cure to TheVirus. HumanityEnsues.
* '''Subverted''': John is bitten by a zombie, but does ''not'' become one, either because he is immune or because he took the cure to TheVirus beforehand.
* '''Double Subverted''': ...However, a horde of zombies [[ZergRush attack]] John, who is subsequently bitten by so many of them that the anti-virus is no longer effective.
* '''Parodied''': John, a lazy, inarticulate and inexplicably still-alive survivor of the zombie apocalypse becomes a lazy, inarticulate, unnoticeably undead victim of the zombie apocalypse. Living characters [[Film/ShaunOfTheDead keep him around because his infection makes no difference, as long as nobody puts their fingers in his mouth]].
* '''Zig Zagged''': John was bitten by a Vampire and freaks out about changing, but he doesn't. Then he change slowly into a vampire, then spontaneously turns back.
* '''Averted''': John either survives the ZombieApocalypse or is killed, but either way he does not become a zombie.
* '''Enforced''': "EverybodyLives...that's too boring. {{Everyone Dies|Ending}}...too dark. How can we add some dramatic tension? '''WAIT! I'VE GOT IT!!'''"
* '''Lampshaded''': "One day he was fighting by our side...the next...he was bitten, [[TitleDrop and then John was a zombie!"]]
* '''Invoked''': The BigBad releases TheVirus specifically to make John a zombie.
* '''Exploited''': John allows himself to get bitten by a zombie, hoping he has the willpower to fight off the horde with his newfound abilities.
* '''Defied''': John is injected with the cure to TheVirus just before it's too late.
* '''Discussed''': "No, John didn't die. He turned into a zombie."
* '''Conversed''': "...and then John was a zombie. Wow, way to add some emotional value!"
* '''Played For Laughs''': John becomes a parody of a zombie, a shambling idiot who demands brains.
