So he has the strength to instantly break through walls. The only characters we've seen show that level of strength to just blast out a wall in a single punch are characters like Yang and Nora, who gain Strength advantages as they fight or using explosives such as Nora's grenades. If this was a common ability, Ruby could have simply blasted through a wall rather than having to fight with Mercury to get away from him towards the end of Vol 4. If this is the case you have a character with ridiculous speed, ridiculous strength, the ability to fight at top standards at close, medium, and long range.Now you can ask Nathan the response Mod's have to these types of characters, seeing as this was the issue addressed with before they had him rework Nathan Eau.
The only real weakness he is said to have is that he doesn't plan and does not actively shield with aura. Due to the fact that he is apparently unhittable, those don't really come into play. I have literally seen you have him take on 5-7 people at once, some of those in the higher class mates, and not go below 95% aura.
