Characters: I Am Weasel
IM WeaselThe 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.Voiced by Michael Dorn
- The Ace
- Badass Pacifist: For the most part.
- 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.
- I Am Not Weasel: The Trope Namer, sort of.
- Case in point: Red Guy mistook him for a squirrel.
- 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
- Straight Man
- Weasel Mascot
IR BaboonThe 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.Voiced by Charlie Adler
- Butt Monkey: No pun intended.
- Chaotic Stupid
- The Ditz
- Green-Eyed Monster
- Happy Dance
- I Just Want to Be Special
- Naked People Are Funny: His big red butt.
- The Resenter: Of course.
- The Rival: In earlier seasons.
- Small Name, Big Ego
- Third-Person Person
- Too Dumb to Live
- Wicked Stepmother: Well, wicked stepbrother but neither him nor Cinder-Weasel had any parents in the Cinderella parody.
- Villain Protagonist: Somewhat.
The Red Guy/I.B. Red GuyThe 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.Voiced by Charlie Adler
- The Devil Is a Loser
- Flaming Devil
- Large Ham
- Otherworldly and Sexually Ambiguous: In spades. Considering he's a jack-of-all-trades, he can pull any kind of role of either gender... and not only that, whenever he plays a female, he clearly has a bust.
