Thanos's Durability is beyond what they could do to him with Blunt force Trauma. They would literally all have to hit him at the same time in the same area to KO him. I dont' see that happening.
Jesus Omega... what on God's Green Earth are you basing this on... I figured you would say this... Honestly, most of these guys are one or two shot.. with Marvel and WW last to go. None of them have the h2h firepower to put him down, even as a team. However, he certainly has the firepower to put them down.
Do you call Thanos punching Mar-veil from Saturn to earth beating someone in h2h? Do you consider Thanos engaging in h2h and wrestling with Drax and causing the planet to explode.. beating someone in h2h? He went through a planet of warriors strictly using h2h. Remember when he punched SS to death in like 6 punches? Does that count? Do you remember when he engaged Champion with PG in a fight… he made him look like an unpolished brute.. Dodging, evading, punching him back, goading him etc etc. He didn't win via h2h but he made someone who is an acclaimed master of various fighting arts across the universe look like a tool. Do you call casually dismissing via pimp slap some of the strongest people in marvel.. engaging in h2h. He casually dismissed Drax, Hulk, The Thing, Hercules etc etc.. casually doing so like they were weak feebs.. How often do we see Thanos casually dismissed in such a manner like he does others. He's trained gamora to be one of the deadliest assassins in all of marvel, which emphasis the amount of MA he himself knows. Is your claim that he can't get the job done h2h against this team? He backs more firepower in his punches than anyone on this team and more than multiple members of this team. Not only does he have a lot behind his punches, he doesn't even need to do so, and can casually pimp slap most of these guys away. The point is, he has good fighting ability, good reflexes, packs way more behind his punches than anybody on this team, and is way more durable than anyone on this team.
This team collective makes Thing and Mar-vell look like chumps in melee, though. I'd give almost all of it's individual members the win against those two.
Aside from Ares, they're all class 100+, and several of them are really fast and/or otherwise hard to hit.
You need to read up on Marvells h2h abilitys, and you are forgetting that was far far weaker Thanos before Death brought him back to life, if Thor amped by the power gem could only just harm him, they don't have much chance, plus non of them are faster than Ganymede who speedbltzed Surfer and easily beat the crap out of Terrax and Thanos easily dealt with her speed.
