i have only ever read one of his comics... but apparently the creator of Invader Zim created a bunch of comics.

i will pay good money for anyone who has them or can get rhem.

Do you know the name of the series so I can keep a lookout?

"Johnny The Homicidal Maniac"
I'm not sure if he's interested in related titles, such as "Squee" and, I think, "Enore" ... the last one mightn't be related and may be totally the wrong title as I'm working off a very sketchy memory.
