Main [ that’s my secret;; main Bruce ]
Bruce thought the key to recreating the famous “Super Soldier Serum” was in gamma rays, but that all changed when an explosion erupted and Bruce became more than human – became another person altogether. 

Human [ just a genius;; human Bruce ]
Bruce never got involved with the military despite his genius, deciding to keep up with his genetic work rather than try to recreate the serum.

Professor [ shaping young minds;; professor Bruce ]
Life as genius wasn’t much fun when there was no one to have a normal conversation with. So Bruce took up being a professor to help enrich new minds while still maintaining a sense of normalcy. 

Wolf [ call of the moon;; wolf Bruce ]
As a wolf shifter, Bruce was small for his age before the explosion. After the gamma explosion, as a Wolf, Bruce is six feet tall on all four feet and longer than the average school bus.
