People being intentionally difficult with Carver aside, we all know the point is how these characters fair against an attack that crumbles Caps shield.
The shield is...weird. It's always okay with anything below Trans, it was dented Trans tier King Thor, but he swung with intention to hurt. It snapped in half by Cul (magic?) Who was feeling very good about his chances about beating Odin (back when that mattered ).
But Thanos just amplified his energy fist and shattered it.
I'd say he crunches all of them 🤷‍♂️ a swing from King Thor would definitely smash Diana's skull if we replaced Caps shield with her head and Thanos with Mjolnir. And it's not even comparable to Thanos.
