Cobra Commander from G.I. Joe

Cyborg, Tera, Raven, and/or Jynx from Teen Titans

Toph and/or Sokka from Avatar: The Last Airbender

Brock Sampson from The Venture Bros.

Jaba the Caveman from Martin Mystery

Gwen Tennyson (any version) from Ben 10

General Skar from The Grim Adventures of Billy and Mandy

The Giant Chicken, Adam West, and/or Meg from Family Guy

Perhaps I'll suggest more later when I have more time.
