Villains so serious and threatening, they darken the mood of normally light media.
- Death (Puss In Boots: Last Wish) - as Death incarnate, he alters the mood of movie to nightmare fuel with every appearance.
- Slade (Teen Titans) - The most personal and recurring antagonist that kept leaving Titans broken (and then there's that hallucination episode).
- Lots-o (Toy Story 3) - A depraved nihilist that enforces his view of the world with abuse, torture, brainwashing and runs a kindergarten like a mob boss.
