Hold on! did anybody forget how fast, durable, and strong thanos is! Thanos can go 3 trillion times the speed of light. ( that was without the gauntlet). And she’s not the only one who can destroy planets, you know! He can to! Also, he’s survived reality warping, a black hole, ( which has the destructive capabilities to destroy a galaxy!!!) and ego, the living planets stomach acid! ( which is deadlier than a supernova!!!). Also, he lifted 50 quintillion tons. ( that’s like holding up 148 trillion Empire State Buildings!!!). He’s also a master in magic too. Let’s not forget the double sided blade, that he has. He could reflect close to every that star puts at him. So yeah, I think thanos could win this battle even without the gauntlet. GG star!
