Charles Xavier
Vs
Thanos
OK I will admit that this battle is nearly pointless. My opponent is correct, Thanos is so high up in the marvel character ladder, that even without the Infinity Gauntlet he is nearly invincible. (I think he should be removed from the list for next season BTW)
I have thought about this matchup for awhile and although Professor's powerful telepathy is nearly unsurpassed, I am unsure whether he would be able to beat Thanos. Although I do disagree with the comparison with Moondragon. Xavier has beaten nearly all of the most powerful telepaths in the universe. He was strong enough to beat the Shadow King, and he was strong enough to beat the Dark Phoenix in these scans.
So he is certainly no shmoe in that department, but I still wonder if it's enough. I guess that depends on if you believe Thanos's mental ability would be stronger than another infitely powerful being who's power is ALL mental, with the Dark Phoenix. Here he fights with every last effort until he has collapse himself into exhaustion, until he has beaten a foe which is a danger to everyone in existence. So I will leave that up to you, because it all comes down whether you believe if Xavier's telepathy would be strong enough or not. Either you do or you don't, there's no in between.
Of course the other thing Charles has would be his Mental blast, which is like any other blast, would hit their opponent just like a sonic or energy blast. This would be quite effective and powerful and if done quick enough could catch Thanos by surprise. Although, I am not positive this would be powerful to take the Titan down for good, probably not. At the most it would catch him off guard and possibly knock him down, but that would be just delaying the inevitable.
Than I come to my last and final strategy. This one like anything against Thanos is a long shot. But it was a longshot when he had the Infinity Gauntlet and it was a longshot when he had the cosmic cube, and he was beaten in both instances from that longshot. The other thing is that I have read in more places than one, that Thanos is predisposed to finally lose in the end. That subconsciously he has/wants to lose. If this the case than he can't win the tournament.
So Xavier in his prep time will come to the conclusion that there is no way for victory against Thanos. At first this might be a somber realization but he will come to the final conclusion that he must do what he has to do, what he has always done. Putting the greater good above all. This is a chance not only to defeat Thanos but to end the suffering to the aliens on the planet that Galactus consumes.
Because of the close relationship between Lilliander and Xavier, the x-men have an access to a great deal of their advanced technology and weapons which they have used for the Danger Room, the Blackbird and the X-Mansion to name a few. So because of this close nature it wouldn't be any problem for him to acquire further weapons, in which my opponent agrees he would be able to obtain. Although, I would again agree with my opponent in the fact that he would be unable to obtain anything handheld that would be able to really harm Thanos. That's why Xavier will do what he must and that is to take out a great threat to the universe. With Shiar technology that is capable of destroying a whole planet, Xavier could at least obtain a nuclear type explosive bomb that would destroy antything in it's immediate area.
I would see this match handed this way. Xavier will appear on one end and Thanos on the other with about only a 100 m away. Xavier will immediately go to his astral form and with this form he will talk to Thanos. Thanos, although a brute is not uncommon in communicating with lesser beings. They will discuss many topics including evolution, history, war and politics. However eventually Thanos will tire of this and since Xavier poses no great threat to him he will not rush to Xavier's body. Meanwhile, Xavier's astral form will soar away from this close area. Now the location was said to be a planet so there doesn't seem to be a limit to how far you can be apart as long as as Xavier stays on th planet surface. When Thanos reaches Xavier's body, he will probably scoff at this weaker species and smash his body into the ground. At this point he would have activated the bomb unknowingly installed in Xavier's hovercraft and this will vaporize anything in it's immediate vicinity. If the Shiar have technology to vaporize a WHOLE planet I am sure they have something that would be destructive enough to annihilate Thanos. Unless you believe Thanos is more indestructible than a whole planet.
So now you probably thinking, "What does this do?", Xavier and Thanos have both been killed, so it's a draw. BUT think about this when voting, how many powerful telepaths have you seen be able to materialize from pure energy form? How many telepaths have you seen create their own body? There's Shadow King, Cassandra Nova, Kid Omega, to name only a couple of powerful telepaths. Actually even Xavier has done it before. He has survived death and he has survived as being only pure energy. So I may ask, why can't he do it again? If history is to repeat itself like it's been done and proven again and again, powerful telepaths are capable of returning from death, returning and forming a body, and never truly dying.
So because of this, even though Xavier's body has been destroyed, his mind and astral energy is not. So he has live past this match while Thanos has been vaporized from the nuclear explosion.
As unlikely as it is, you can't deny it's a possibility..
WINNER BELIEVE IT OR NOT Charles "Professor X" Xavier
I mean look at Xavier...he will do what he has too...
