Hakumen

Hakumen is a samurai-esque warrior wielding a sword as tall as he is and wearing a mask that completely hides his face. He is an incredibly powerful individual in the BlazBlue universe, so much so that the player is often told to proceed with caution when confronting him, and at times even advised not to do so entirely. His armor (which is the Susano'o Unit), seems to grant him limitless energy and incredible power, and his sword (a Nox Nyctores named "Ookami") appears to bear the capability to kill characters that otherwise would be immortal, or have rapid healing properties that would make them difficult or impossible to kill. This makes him an equally dangerous foe to both mortal men as well as more powerful beings. It seems that Hakumen finds nuclear weapons to be a greater evil than the Black Beast was. This might be because while the Black Beast did spread destruction, it left seithr which became the power source for the future, while nuclear weapons just completely obliterated any life within its radius and leaves the area irradiated and useless. He was the legendary "Silver Knight" who appeared during the First War of Magic, and lead a band of Six Heroes (including himself) that ultimately defeated the Black Beast. Afterwards, Hakumen warned the people to "change their evil ways", but was exiled and sealed in a place called "The Edge" of The Boundary for roughly 90 years.
