6. Titano

Monkey! Well, ape, but you know, same basic thing.

Titano began life as a super-intelligent chimpanzee named Toto. Not, like, able-to-speak intelligent, but smarter than your average chimp, for sure. So smart that he got picked to be the test chimp on a space flight. Um, test animals don’t need to be that smart, the “test” is mostly whether or not they explode in space. If they don’t, congrats, they passed.

So Toto got stuck in a rocket and shot into deep space, where his rocket collided with a Kryptonite Meteor and a Uranium Meteor. His rocket crashed back to earth, and Tot came out, only to immediately mutate into a huge super gorilla and start rampaging around Metropolis. Also, he can shoot Kryptonite lasers from his eyes. Lois tricked Titano into putting on giant fake sunglasses made of lead, which halted the Kryptonite beams, and let Superman beat him.

There is also a New 52 Titano, but sadly, he is not nearly as big as his predecessor. He only lasted three issues. Sad.
