Hopefully by now King Roach is easy to identify. The rest of the creatures on the page are various possible adversaries. At the bottom, on the left is the freak creature. On the right is the samurai thing.

Not sure who the noseless guy is. I must have just been inventing him as I sketched since I can’t identify him. The KR adversaries that I’ve put thought in to are always recognizable to me when I see them again. I can’t say I remember the details of their stories but I do remember that they had stories.
