Talk:Ultron VS Sigma/@comment-35671553-20181017210729

Ok, so I'm rooting for  Ultron, (gotta support Marvel all the way). Although Ultron is basically unkillable since he can just exist as an A.I, I'm told that Sigma can do the same thing, correct? But in many appearances, Ultron's body is made of adamantium, and is capable of haking other robots and androids. I dont know much about Sigma. Is his power enough to brake adamantium and/or hack Ultron?
