Hank McCoy, also known as Beast, is one of Marvel Comics' most complicated figures. He begins his story as a hero, one of the first X-Men, but over time, he slowly becomes corrupted until he could be seen as a villain himself. From the X-Men to the Defenders to the X-Men, Hank has served on many teams, with his vast intellect serving as a boon to his allies and a danger to anyone who crosses him.
Kelsey Grammar has been confirmed to appear in the MCU in Avengers: Doomsday, likely reprising the role from the X-Men film universe, especially since he already appeared at the end of the Marvels. Looking at his Marvel Comics history, will Beast remain an hero in the MCU? Or will he give into temptation and become a villain himself?
