And yet SBP's planet busting feat is not on par with Terrax's feat or Grey Hulk's. Grey Hulk because he went through something twice the size of Earth and Terrax becaue he shattered a planet with pure strength and didn't need the speed boost to ram through the planet to destroy it.
And of course Gladiator three-punching a planet is better too
And accidentlaly destroying a planet in a fight is a helluva a lot more impressive, IMO. So, Pre-Death Thanos takes that too.
Do you see how completley unimpressive, all things considered, SBP's feat is?
Would Odin kill Prime in no time with what he hit Thanos with? I don't think so. I'd say Prime would as last as long as Thanos.
Odin has one-shotted Surfer as mentioned and obviously what he was smacking Thanos around with was more than that one shot.
Nothing I've seen of SBP screams he has largely above top tier durability if it's above top tier at all. Norrin is one of the most durable top tiers and if Odin can take him out in a single blast, I don't see why several of those blasts wouldn't take out SBP.
