Princess Luna took it, but Micheal Myers and Armstrong were close.

As for suggestions:

Pom Lamb vs Bellwether (from Zootopia)

Darkwing Duck vs Goliath (Gargoyles)

Scrooge McDuck vs Filthy Rich, Indiana Jones, or Grunkle Stan

Peppa Pig vs Caillou

Papa Louie vs Bob Belcher or Cooking Mama

Segata Sanshiro vs Pepsiman

Storm King vs Unicron

King Sombra vs Sauron

Chrysalis vs Mystique or Perfect Cell (because bugs)
