Penetrate is an original ability of Ddraig, it lets him bypass or break any defences, barriers, or any kind of protection the opponent has. This ability has not been seen nor used since he was sealed within the Boosted Gear. Diehauser does not kmow how Penetrate functions or the secret behind it to make the ability worthless, and in my opinion even if he did know Penetrate is almost like a cheat ability since it lets the wielder bypass any defences whatsoever.
