Lt. Colonel Leo Baker

Former soldier turned x-men. His mutant gene activated when he was fighting in the war back then, it was also then when he lost his left arm.

An overall serious man who has a heart of gold. Sees himself a bit of a guardian to most of the younger x-men and students of the institute. While he stays rather passive in most missions he is more of a teacher than tries to actively fight unless provoked first. As he suffers from PTSD it's sometimes hard for him to even deal with situations where violence and fighting is involved.

Overall Leo tries to live his life without regrets and not with a foot in the past while still honoring his fallin comrades. He is supportive of his trans child and has custody of him.
