Hematite

My Steven Universe character.

He fell in love with a human woman who died. Her death hit him incredibly hard and he can no longer reliably summon his weapon or use his powers. He has powers that let him control metal and shape it like liquid to his will. So instead he fights the old-fashioned way, relying on his bulk and physical strength. He often comes across as aggressive, aloof, and uncaring, but he's really a kind person.
