I wish I remember how strong he was without the board. Those movies are so mediocre that I don't really feel the need to go back and see the fight scenes. I remembered he tanked a blast from Silver Surfer ( a casual blast created a mid-sized crater/blew up vehicles), and Vaultdweller said his armor withstand temperatures comparable to the surface of the Sun. So based on that I don't imagine anyone could really do much damage to him. Maybe FOX Colossus, Angel Dust, Vision or some brick characters could knock him around at least.
