If I were to bring back any classic character, it would have to the "The Blue Racer" from the DePatie-Freleng crew. I've seen a few episodes floating about on YouTube and while many can complain of the quality of 'em, I think they have a certain charm which still makes me laugh. That and they're so much cooler when directed by Gerry Chiniquy.

So yeah, I did a character sheet of the rapid lil' reptile along with his short-lived quarry, the Japanese Beetle. I reckon if this series were to be resurrected, the one change I'd make to the designs is to make the beetle less "insulting" as you can see. It worked for "Batfink" when they changed Karate's look, so why the heck not? XD
