7. Hedorah
You might think a smog monster is stupid, and you’re right. In fact, he was named for hedoro, which roughly translates to “sludge” in Japanese. In a way, he’s kind of like a Pokemon since he has so many evolutions (one of which looks like a flying saucer). But for that reason, I think he’s pretty cool. It doesn’t hurt that his eyes were meant to look like vaginas.
