he used outside tech to capture mad thor. i presume he wouldn't have it in a ring-type situation that is the default standard for these battles. just his strength and blasts against supes and cm.
hmm, i wonder how thanos does with magic? haven't seen him go against it often. a few lightning bolts might just get his attention. combined, i'd say supes and cm would have the PHYSICAL power advantage, and thanos is smart but supes and cm are NOT slouches - besides, in a ring, his brains wouldn't be of much use, it would come down to power. though he whipped him like a mule, it's taken thanos several blows to ko ss h2h, and ss wasn't using speed for some reason. if he did that here, the supes or cm would be getting free shots to stop him.
with supes and cm using their powers to the fullest and being uber po'd, they pack a LOT of power. i could actually see this going either way.
(damn, feels like i'm going against thanos a lot lately, but he's been put in some damn tough threads!)
ps-somebody PLEASE explain why the hell thor isn't blocking/absorbing that stupid vision blast with his hammer?? i've wondered that for about 20 years since that issue first came out!
