Characters / I Am Weasel

I.M. Weasel

The main protagonist, a heroic weasel, who is everything I. R. Baboon wishes, and possibly imagines, he was. Weasel is often seen volunteering to help those less fortunate than himself, or contributing great deals to society by erecting monuments and structures with beneficial results.

  • The Ace: He's famous, brilliant, multitalented, and loved by everyone.
  • Badass Pacifist: For the most part.
  • Broken Ace: Later episodes start to show some dents in Weasel, where he often shares the Butt-Monkey role with Baboon.
  • Butt-Monkey: Weasel would develop his fair share of bad luck in later episodes (thus toning down his "Mr. Perfect" character).
  • Chronic Hero Syndrome: Will go out of his way to do the right thing in any situation.
    "One life lost diminishes my own."
  • Cinderella Circumstances: In the Cinderella parody.
  • Fate Worse Than Death: The Princess in the Cinderella parody. Marrying her was something Weasel considered to be the trope.
  • Hypercompetent Sidekick: Weasel plays this role in episodes like "Baboon Man and Weasel Boy" or "I.R. Robin Hood" where he is the assistent to Baboon's Idiot Hero.
  • I Am Not Weasel: The Trope Namer, sort of. Case in point: Red Guy mistook him for a squirrel.
  • Insufferable Genius: He comes off as this from Baboon's perspective.
  • Invincible Hero: More in earlier seasons.
  • Large Ham: Less so than the Red Guy, but it's still notable at times. He gets EXTREMELY hammy in the Franken-Weasel episode.
  • Nice Guy: Calling him nice would be an understatement. He was first shown giving a dying boy a kidney transplant. He becomes slightly more egotistical and neurotic in later episodes, though considering how much his kindness often gets him, it's often justified.
  • Only Sane Man: Often the show's universe appears to almost equally brainless as Baboon, with Weasel usually playing the Straight Man.
  • Parody Sue: In early episodes, Weasel played The Ace rather genuinely, at rather unrealistic levels.
  • Surrounded by Idiots: As the seasons progress he becomes a more pretentious Small Name, Big Ego that suffers due to living in a world of fools.
  • Wicked Weasel: Inverted. Weasel is a courageous, selfless hero who is great at everything, pretty much the exact opposite of that trope's cowardly, self-centered sociopath that often has to resort to trickery and deceit to accomplish anything. This characterization of near-perfection serves primarily to set him up as the comedic Foil to I.R. Baboon.

I.R. Baboon

The other main character of the series. Most times he is seen taking a back seat to Weasel's escapades, and feeling resentful and jealous towards him. But there are those rare occasions when the two act as the best of friends.

The Red Guy/I.B. Red Guy

The same character from Cow and Chicken (only he goes by I.B. Red Guy or the many names that refer to his not wearing pants), who acts as an antagonist of the series whenever I. R. Baboon isn't fulfilling the role.

  • The Devil Is a Loser: If he's not running some aimless fraudulent business, Red Guy will sometimes be the damsel in distress Weasel and Baboon need to protect.


The Weasel's blonde and attractive nurse assistant. A minor character, she made most of her appearances in Season 2 and went out of focus afterwards. She is often speculated to be Weasel's girlfriend.

  • Big Eater: Lullabelle is shown to be this in the ice fishing episode.
  • Femme Fatale: "Weasel, I'm hungry..."
