I honestly don't think any artist drew more different monsters than did Jack "King" Kirby. The variations on a theme are astounding. Some of the designs are stunning and some are stupid, but while all recognizably Kirby, they are all different. I've learned that comic book monsters come from all kinds of places, but mostly from myth and outer space. Those from myth can be pretty awesome and those invaders from space can frequently be pretty stupid, often drawing all sorts of conclusions about the whole of mankind from microscopic sample sizes and flying away in terror, vowing never to return. Here's a ginormous batch of those myriad and mighty Kirby monsters.
Happy Halloween amigos!
