Thanks to MHA, One Punch, and One Piece, there are dozens and dozens of weird and imaginative ways a thing can be a power, which makes my choices lame in comparison, but the most recent one I've been liking has been Impact Manipulation. There was a villain who had an impact absorption power, but I'd want a more in depth version of that. To absorb, contain, and amplify impacts.
To be able to contain physical stress my body feels, like being punched or hit with objects, or even the resistance an object exerts when stress is applied to it. Like say I lean my hand against a wall. I'd be able to absorb all the force that the wall is using to keep my hand from passing through it and reduces the structural integrity of it to nearly zero. Also, being able to contain that energy allows my body to become incredibly stable and adds to it's ability to absorb physical forces, so eventually even buildings falling on me wouldn't hamper my ability to move at all.
To sum that up a bit, if I was punched by All Might, the first punch would send me flying, but I'd absorb that as much as I could, plus the damage of being sent through multiple buildings, and if All Might punched me again at the same strength, I'd barely react to his punch, while also absorbing all the force that was put into the second punch, making me even sturdier.
Add on to that the ability to amplify the severity of the impacts I can deal out and I'd be a veritable juggernaut. But I wouldn't take that name for reason. Names are hard, but I guess After Shock fits well enough. And I'd totally be a villain, one to follow under Stains creed if I'm to go full weeb, which the length of this post seems to imply.
