Dr. Zygote - master of evolution

Dr. Zygote was a villain from the cartoon series Mighty Max.
The evolution-obsessed Zygote was encountered by Max and crew during his attempt to "reset time" by de-evolving everything back to primordial goo and starting over. During the encounter, Zygote turned Max's iguana into a dinosaur but ended up evolving himself into a large-brained floating creature. After his escape, Max again foiled his plans when the doctor attempted to process the DNA of a psychic teenager. The encounter left Zygote evolved even further into a floating ball of light, at which point he cared nothing for evolution - only for the beauty and music of the universe.
