because sometimes, being just plain awesome... isn't good enough.

Ryohei is powerful by nature and his ability to live his life to the extreme, makes the dying will flames completely ineffectual on him. He is able to use his basic boxing skills from the beginning which makes him seem fairly powerful however he is never on the level of the other guardians until he trains with Colonello. Colonello teaches Ryohei is Maximum Cannon, which enables Ryohei to use his fist the way Colonello uses his shot gun to unleash a single overly powerful shot that is strong enough to break boulders and destroy everything in its path. Unfortunately he is only able to use this ability once and can only do it with his right hand.

During the Ten Years Later Arc however Ryohei is able to show off just how much his skills were increased. Ryohei is able to box better and faster since he was able to learn the footwork Lussuria used during the battle for the Sun Ring. He is also able to multiply that ability and use it on his hands in order to deal several successive blows with the same strength as the Maximum Cannon, he calls this technique the Maximum Ingram. Because Ryohei's unique cell structure and the elasticity of all of his cells Ryohei is unable to use his over powered techniques consecutively during the Varia Arc, however with Ryohei's ability to use his sun attribute flames he is able to increase his healing speed to roughly 10x the original speed cell regeneration.
