'''Basic Trope''': Character becomes more of a jerk over time.
* '''Straight''': [[KnightInSourArmor Leon]] starts out as an AloofAlly, but he still clearly respects his TrueCompanions. However, over time, he turns into an {{Insufferable|Genius}} {{Jerkass}}.
* '''Exaggerated''':
** Leon starts out as a ShrinkingViolet with a touch of cynicism wearing JadeColoredGlasses. Near the end, he went JumpingOffTheSlipperySlope.
** FaceHeelTurn.
* '''Downplayed''': Leon goes from a NiceGuy to a slightly irritable jerk.
* '''Justified''': Leon's life has been falling apart and he's just stressed.
* '''Inverted''': TookALevelInKindness.
* '''Subverted''': Leon suddenly acts like a total {{Jerkass}}, but in reality it's a [[JerkassFacade defense mechanism]] because he's stressed out.
* '''Double Subverted''': ...but then [[BecomingTheMask flips around and becomes a total douchebag]].
* '''Parodied''': Everyone refers to Leon being unusually nice while he's [[KickTheDog running around kicking hobos in the face]] ForTheEvulz. They keep on acting like he's being nice even when he sets a guy on fire for no reason.
* '''Zig Zagged''': Depending on his mood, he's either a jerk or kind.
* '''Averted''': Leon's characterization remains about the same. While he's still snarky, any time he goes too far such as [[TooSoon making a crack about]] Bob's DoomedHometown, he apologizes.
* '''Enforced''': The creator of the series wants the fans to focus more on other characters, so he makes Leon just unlikeable.
* '''Lampshaded''': Someone notes that Leon wasn't always this much of a jerk.
* '''Invoked''': JerkassBall
* '''Exploited''': The BigBad knows Leon is TheChosenOne and wants to make sure he stays a jerk so no one will support him on his journey.
* '''Defied''': Even though Leon has some stress in his life, he makes sure not to take his anger out on anyone.
* '''Discussed''': "Man, Leon's really turned into something else."
* '''Conversed''': "Remember when Leon was a NiceGuy? No, neither do I."
* '''Deconstructed''':
** Leon has been through [[AFateWorseThanDeath things worse than death]] while fighting [[EldritchAbomination things that should not exist.]] This transition is showing how he is falling apart and may end up [[FaceHeelTurn switching sides]].
** Leon became such a JerkAss, his friends and family no longer want anything to do with him.
* '''Reconstructed''': Leon's friends help him get through these traumatizing experiences, letting him know that [[YouAreNotAlone he isn't alone]]. This helps Leon pull himself back together.
