3. Mr. Mind

Captain Marvel villains are friggin’ great. Like, we just had one who was a giant robot man brought to life by nuclear energy. This one was an evil talking caterpillar.

Mr. Mind came from a world of underground worms, most of which were unintelligent hive mind creatures. Mind was born a super-intelligent mutant. But, being on an entire planet filled with worms, he couldn’t really do much but come up with evil schemes. Eventually, an alien scientist visited his planet, and Mind took him over, using him to craft several devices to help Mind in his super villainy.

Mind eventually found his way to Earth-S, the home of the Marvel Family, where he assembled the Monster Society of Evil. Mr. Mind went on a vicious rampage, racking up almost 200,000 counts of murder. For which he was sentenced to the electric chair. Yes, in the DC Universe, someone had to fit a tiny electric chair helmet over the head of a caterpillar wearing glasses.

This, however, didn’t kill Mind. He continued to menace the Marvels for decades afterwards.
