Thanos(BLAZE)
vs.
High Evolutionary(PHAED)
This is, in my opinion at least, the best match up thus far in this thing. Both characters are master planners and extremely intelligent. Both have an impressive array of powers that are pretty high in strength level (at least most are). The Evolutionary has an impressive piece of armor and psionic powers that would make Xavier jealous. As far as knowledge goes, both opponents should have a good amount of info on each other as both are huge knowledge ****es.
High Evolutionary's cosmic awareness would make it extremely difficult for Thanos to get in any type of sneak attack, but the Titan could still track him down; he's not invisible to technological means of tracking and the Titan has some of the best tech out there. So, that would force a face to face confrontation.
Both are sophisticated beings, but I doubt there'd be much banter between them before they begin to throw down. Probably be a lot of verbal jabbing during the fight though.
The Evolutionary has the ability to rearrange matter at the molecular level, but Thanos has shown to be extremely resilient against reality manipulations, such as in Thanos Quest. The Titan would be able to resist any attempt to change his molecular structure. Thanos has shown to be able to manipulate matter as well, but I don't think it would work on the Evolutionary, himself, either.
The Evolutionary can create life, psionically, and, potentially, create an entire army for Thanos to face. This would more than likely be against the rules though, so I won't go in on this (I was told I could not use any of Kang's servants and it's basically the same deal).
As far as telepathically manipulating the creatures in the N-Zone to attack Thanos, that would work. However, the N-Zone is a colossal place and, personally, I don't think the Evolutionary would be able summon that many creatures in the area before the fight is over. What creatures he does/is able to summon, the Titan would make short work of. Granted, there are, potentially, powerful creatures in the N-Zone that could, conceivably, be in the area for the Evolutionary to summon to his aid. But, Thanos has been shown to take out entire armies single-handedly (Cosmic Powers) and has taken down beings even more physically powerful than himself (such as his Magus clone). Add to the fact Thanos' tech and intelligence compared to that of some N-Zone creature, and the Titan would have little trouble in dispatching the fodder.
The only way this would really be handy for the Evolutionary is if he needed to get Thanos off of him to regroup.
As far as the Evolutionary's armor goes, it's powerful, but hardly indestructible. It is an extremely tough nut to crack, but one with sufficient strength can tear it apart, as the Hulk has shown when he confronted the Evolutionary. Now, Thanos is just as strong as the Hulk (base strength), and is also able to increase his physical powers to higher degrees via cosmic energy manipulation. He would definitely be strong enough to tear the High Evolutionary's armor off of him.
The Evolutionary's suit can also "heal" him and bring him back to his perfect state of human evolution from pretty much any injury, even a single cell. But, this is not instantaneous. Mortal injuries, such as having half of his body vaporized for example, would take some time to regenerate. It would definitely not heal fast enough for him to continue the fight.
Also, something to keep in mind, is that under the armor, the Evolutionary is a human. Albeit the ultimately advanced human, but a human none-the-less. Without his armor he's far less durable than the Titan and would not be able to take, for instance, a blast of cosmic energy from the Titan, full force.
As far as energy blasts go, I've never really seen the Evolutionary use them much. So, I can't rightly say whether they are weaker or stronger than Thanos' cosmic blasts. However, I can say that Thanos is able to increase the potency of his blasts enough to knock Galactus on his ass.
As with the energy blasts, I've not seen enough of the Evolutionary's force fields to rightly comment on their potency. But, I can say that Thanos' are some of the most powerful I've seen in comics. His personal forcefields have even withstood a blast from Omega, a being twice as powerful as Galactus. And he pretty much always has them on him when he's knowingly going into a fight.
As for intelligence, I'd say they're about even scientifically, with the Evolutionary having the edge in genetics and the like. As far as tactical planning and battlefield strategy goes, Thanos has the edge. The Titan also has the experience edge, having been in the game hundreds of years longer than the Evolutionary has.
Thanos also has an impressive array of devices he could use. I've mentioned the stasis gun before, but he could also bring in the power orb which he stole from Tyrant to increase his power levels. He could also create a device to harness the negative energies of the N-Zone to use as a weapon against the Evolutionary, such as creating an explosion of anti-matter.
All in all, this is a very good match up and should be an excellent game of wits as well as a good old fashion brawl. Still, Thanos has battled and outmaneuvered being just as powerful as him, and some more powerful. So, he's no stranger to being in the fight of his life. The Titan also has much more experience in huge fights compared to the Evolutionary. And that experience should help.
As I've said a couple of times now, this will be a damn good fight. But, in the end, the Mad Titan should pull out the victory.
