Characters you find repulsive.

Dolores Umbridge was totally gawdawful, wasn’t she?

From “The Dirty Dozen”, I’ll add Sgt. Clyde Bowren (Richard Jaeckel)… that smug little prig.
Archer J. Maggott (Telly Savalas) was pretty damn repulsive too.

The vomiting frog from the simpsons. I’m not sure which Halloween episode but it’s the “Harry Potter” spoof. Made me nauseous.

I second Fat Bastard from the Austin Powers movie…but I think I’m supposed to find him repulsive.

Hee! Absolutely. Cannot stand that little toad.
