By far one of the most underrated cartoons ever made. I absolutely love Troma's animated version of the Toxic Avenger - even though the cartoon is FAR tamer than the movies. Toxie's cast of characters are so much fun - I'm particularly fond of Headbanger. Some consider it a failed attempt to capitalize on TMNT, but I completely disagree. Currently, you can only find the animated series in the complete movie box-set. I'm still holding out for Troma to release the entire cartoon series on its own.
