I have been thinking the same thing for a while. Here are my ideas for his leader powers and style. Base on the lore he seems to be more of a defensive hero so he should have some fortification ability and have mines early on. He also doesn't like how his people were used for suicide missions, so he should have some powers to help keep them alive. It shouldn't be a full heal as he is a brute, but more of a defense matrix that give his troops more survivability. It could be called atriox's matrix. He should have meme beam, but not three as for his ultimate he would fire a giant laser onto the battlefield. I'm thinking they could call it devastation.
