Zack

Zack is thoroughly an enigma. He's been a Final since he was very small and, with a very strong elemental-type final, his appearance makes it very obvious that he's not your average person, so his family has hidden him away ever since its manifest. This hasn't been great for his mental health.

With his final based around shadows, Zack is able to shift into an incorporeal form and do as he pleases, though primarily he uses it just for getting around. He is sometimes able to shape shadows around him, too, though he isn't able to do this on command.

He eventually runs away and tries repeatedly to kill himself, under too much stress of considering himself a burden and a danger to his family. Eventually he's found by one of the Final communities and coaxed into one of their group homes, where they try to help the anxious, depressed wreck of a kid come to realize his own worth again.
