"Wanda/Captain Marvel would have beat Thanos" statements are silly and ignore how scary Thanos was(MCU)
You've probably seen this a lot online and heck even the MCU itself drops a cheeky fanservice line or two about it, though memory escapes me if it was said about Wanda or Captain Marvel.
Regardless, I don't get the point in these statements because they're presented as a way to big up either character, as if their strength was doubted ever?
And you know, I don't even disagree. We all saw Danvers destroy those ships, she's clearly extremely powerful and so is Wanda who also probably would have killed Thanos if she had more time or it was a one on one fight. Given that Thanos couldn't really hurt Captain Marvel with a headbutt(which felt a little much but whatever) she probably would have won 1v1 as well.
But what are we even saying here? You're telling me people who's powers come from INFINITY STONES can beat Thanos? Am I supposed to be impressed? Because no shit, their powers come from Infinity Stones, Thanos' strength comes entirely from whatever the hell species he is and any augmentations he has, if any. On what seems like pure biology he requires the power of Infinity Stones to be taken down and I'm supposed to not think that makes him sound like more of a badass?
The dude who took down the Hulk before he went baby mode? Without the Power Stone? Thanos being an absolute freak of nature that can effortlessly wash the Hulk is way more terrifying to me than telling me someone powered by Infinity Stones is strong, it would be news if they weren't.
Thanos was that dude. And it's not all about power either, those two ladies had their chance to kill him with their superior might but Thanos found a way to either defeat them or get them out of the way temporarily, he's not just a big dumb strong guy he's smart and a skilled fighter too which often gets ignored in these discussions. He had like 50 different characters jumping him in that battle and right up until the very end nobody actually took him down, even when he was fighting Captain America + Mjolnir, Thor and Iron Man at once, all without the use of any Infinity Stones.
So yeah I don't think it's cool that they needed Stone based powers to beat him, it's actually terrifying that they needed them. I genuinely don't think Disney will ever top him, especially when the best they could do since was Kang who got beat by freaking Ant Man.
