Evil Professor Hackle?

Don't know why I never shaded this pic, but I like it well enough without the shading. Professor Hackle is actually a nice old tom kat on the show. This was a entry from the Monthly SWAT Kats Art Challenge I submitted. The theme was to draw any character from the show as how they might be in an alternate dimension. An episode in the series had the SWAT Kats going into an alternate dimension where some who were good were bad, and vice versa. So I had Professor Hackle be an evil ol' inventor, building weapons of destruction, instead of his normal inventions for helping "katkind".
