It’s been two years and we don’t know nothing about him or what doomfist was plotting.
He fights for is kind, so that would make him a martyr of null sector? Is he even part of null sector?
Hopefully he is an overwatch level threat, cause we need more villains besides Talon members as playable character
He’s an edgy zennyatta
Funny joke
It is even F U N N I E R the second time
Won’t you give me a heart tho? 
It’s very very likely he is actually the leader of Null Sector, and I’m sure we’ll learn more about him in the OW2 lore, or maybe sooner.
During the Storm Rising stream with ohnickel, Jeff said that the omnic’s plans had to be put on hold because Doomfist got arrested - now that he’s out, their plan can be put into action, and that plan is the Null Sector invasion.
It’s very likely that we will learn more about him in OW2, maybe even get him as a playable hero.
