Moving back into the Silver Age and we're kicking off with something that really set the standard. Instead of each member of the team having a individual chapter and foe, here we get one bad guy and wow. Giant alien starfish; didn't see that one coming. 

I love this guy. He's so simple yet horrifying. He's a starfish and he's going to conqueror your planet! Why? What does he need a planet for? And HOW is pretty darn creepy. He sends out waves of little versions of himself and they affix themselves to your face, letting him see everywhere. 

I also love his introduction. He lands on Earth and explains his plan to some starfish in the ocean, justifying they must be relatives of him. He hasn't been used that much and I think that works in his favor, so when he pops up it's a THING. He's got enough appearances to be recognizable but not enough to be overexposed.
