Does Thanos have his space ship technology at his disposal? In a straight-on brawl, I'm fairly sure the guy would soon find himself in a place he doesn't want to go to. Read: Magneto smashing him with a random satellite or a space station, Stryfe hitting him with a couple of asteroids while Exodus mind-rakes him 'till he bleeds from the nose... all this while Exodus holds him in a telekinetic grip, of course. 8/10 to the three - Thanos wins if he can surprise/outsmart them.
I would like to see Exodus mind rape Thanos because Thanos is a pretty powerful telepath and I think he would win even without tech help.http://www.corvusonline.net/thanos/powers.html
Oh, sorry, an internet source? It has to be right.
Thanos is very overrated. I'm not saying he's a blow-over, but these guys are a team of extremely potent and vicious mutants. Exodus' teleblasts are shown to be easily lethal to even experienced mutants. And wheter or not he can beat Thanos telepathically, the T-Man is still faced with three extremely notable telekinetics.
Stryfe is also a telepath, so Thanos is facing the master of magnetism and two brilliant telepaths/telekinetics. And Magneto also has showed a degree of telepathy, whether or not he has done it without his modified helmet is a mystery to me, though.
How about Magneto ripping him apart with Stryfe while Exodus keeps him contained? Anyway suits me. In an all-out fight the team of three takes the majority.
