Laz Alonso. I think most people know him from either Avatar or Fast & Furious. Mostly I really, really wanted to stick to someone who was Afro-Latino so he works out well! You're right though, there are interesting parallels. I feel like he must have at least trusted Genji to some extent to allow him to stay on Blackwatch, you know? But I also feel like once he really became Reaper all of his hatred for just about anything was amplified so that might explain some of the Omnic hate, even though I think it was still pretty presnt during his days in Blackwatch and before that. He definitely won't have anything nice to say about Angela, though. haha. As much as he blames Jack and Overwatch as a greater whole for where he's at now he definitely lumps his 'condition' heavily onto her.
