This is Killer Croc, AKA Waylon Jones. He was born with a mutation giving him incredible super-strength and a crocodile-like appearance. He has become more reptilian over time due to genetic experimentation. Despite his brutal savagery and heightened reflexes, his animalistic mentality results in lower intelligence.
I drew it first with pencil in my sketchbook, then I scanned it in to my computer and colored it in Photoshop.
For the background I used a Rust texture by ~awjay (
