Blu is a master of intelligence and agility as opposed to brute strength. Though he does posess more strength than most mortals (as he is, technically, mortal himself) he prefers not to rely on it as much as his agility.
He is also a practitioner of kanji magic. He has no elemental or ki powers himself... rather he invokes power directly from symbols. The upside of this is that the options are near-limitless. The downside is that he needs a split-second to write the kanji, the effects are generally temporary, and the power is dependent on the catalyst used to create the symbol (blood being the catalyst of choice due to power and availability).
Blu, though mortal, does not age. His past is a mystery--he doesn't know his own name, origin, where he learned his magic, his purpose in life--anything. He simply wanders, enjoying life as that's all he can really do. For Blu, enjoying life normally involves either fighting, flirting, or preferably both.
