punch a titans head into a building

Thats like a normal person kicking another person into a wall. Kanoh calmly kicked Ohma across a hallway with 1 kick

Vastly stronger then eren who could carry a giant bolder over his head

Haruo has carried 3 times his weight in goats while going up a cliff with 1 hand. Thats not much in comparison

Reiner him self can cause craters

Every character in Kengan can easily make craters, Akoya was literally creating mini explosions by bashing Cosmo on the sides of the arena

what kinda hax do kengan characters have to help them go through Reiners amor

Grapplers can just choke him out, Hatsumi can damage you despite of armor or thicc skin, weak points are still a thing, there are ways to get around it

Reiners amor not even kuruki’s devil lance would be able to go through it and can pierce through steel.

Reiner would never lay a finger on Kuroki
