The Beast is a weird one. He started as just a dude with big hands and feet who could also jump around. But then he experimented on himself and turned himself into the world’s earliest recorded furry. He tends to be the X-Men’s official science guy due to his intelligence and high-falutin’ attitude.
He was also the first X-Man to cross the desert and get himself on the Avengers, setting a precedent others would later follow. (Scarlet Witch and Quicksilver would be the first mutant Avengers but neither were ever X-Men). Beast would continue mutating later, when his secondary mutation turned him into a cat-man.
Experimenting even more with his own DNA turned him into the current neo-classic Beast we have now. I mean, I like it better that friggin’ cat-Beast, and I like the Morrison X-Men run.
