Playing With / Motive Decay

Basic Trope: A character, usually a villain, loses his complex motive in favor of a simpler one.
  • Straight: Green Fist, a well-meaning eco-terrorist in Season 1, starts doing things more for fun in Season 5.
  • Exaggerated: Green Fist starts off as a nice guy, donating to green charities, promoting environmentalist movements, etc. He becomes a terrible villain committing heinous crimes purely For the Evulz in his second appearance.
  • Downplayed: Green Fist, a well-meaning eco-terrorist in Season 1, starts doing things more out of his ego in Season 5.
  • Justified: The Dark Side Will Make You Forget
  • Inverted: Black Blight starts off wanting to kill all plant life for kicks, but later gains a more complex reason.
  • Subverted: Green Fist remembers his reason in Season 6.
  • Double Subverted: Only to forget in Season 7.
  • Parodied: Green Fist starts off as a humanitarian (And no not that kind of humanitarian), then quickly becomes a Card-Carrying Villain.
  • Zig-Zagged: And because of a war between the writers, alternates every new season depending on who's writing him.
  • Averted: Green Fist is still as complex as ever even as the show enters Season 21.
  • Enforced
    • By having him start with a noble motivation, the writers can make Green Fist seem more complex. By removing that complexity after it has made the character more accepted, they make him simpler to write.
    • The story has An Aesop about obsession.
  • Lampshaded: "Something tells me this isn't about the environment any more..."
  • Invoked: Someone is manipulating Green Fist to move away from his original goal.
  • Exploited: Bob breaks Green Fist by talking about the way that his original goals have been corrupted, causing him to surrender.
  • Defied: Green Fist resolves to remember what the mission is about.
  • Discussed: " you remember why you even started all this?" "...what?"
  • Conversed: "Yep, Green Fist has totally lost it. This show has totally jumped."
  • Deconstructed: No one in Green Fist's army respects him anymore, as they feel he has lost sight of his goals. They thus plan to overthrow him.
  • Reconstructed: The above, but instead of overthrowing him, they intend to remind him of his goal. He may or may not remember.
  • Intended Audience Reaction: Green Fist has lost so many times to the heroes, he has developed a vendetta against them. What started as a simple mission to save the environment has degenerated into a pursuit for revenge.

What was I going to go back to Motive Decay for? Eh, who cares? Muhahahaha!
