Power, if applicable: Ages twice as slow as normal (looks 16ish, is 35)
Where do they live?: Victory
Personality: Very cranky, very cynical. This whole aging thing has been a curse his entire life, because there is nothing more depressing in the world than being eighteen and legally able to join the career that you have all but lived in because they are the only people you were allowed to know … but look nine (seven) and be denied access. He got in in the end, of course, but it took willpower (and temper tantrums) to manage it.
His actual age, emotional age, mental age, and physical age are constantly clashing with each other in new and unique ways that have so far been fairly unknown because the only other known “immortal” is his mother, who got her power when she was twenty. At best guess, his physical age is fifteen/sixteen, his emotional age is twenty-threeish, and his physical and mental age are around thirty-five. Physically aging twice as slow didn't mean that he was mentally twice as slow, so he's managed to pack thirty-five years of experience and education in his time.
Appearance: He is slight and looks younger than he physically is, which is already ridiculously young for his actual age. Whoever he dad was, he didn't add much to Mallory's appearance and he clearly takes after his mother with his dark brown hair, blue eyes, slight frame, and a death glare (that does very little good for him). There is hope he'll hit his growth spurt soon, but as he gets closer and closer to being his full adult physical age, that hope is quickly dwindling.
