Ratfist is a webcomic by Doug TenNapel. You can see the titular character to the left as he is a sort of amalgam of Batman and Earth Worm Jim. EWJ is another character created by TenNapel.
The strip is at times silly and poignant but always worth a read. The whole story is collected so if you start at the link above you can read the whole thing and get a beginning, middle and end.
