Byakko

Byakko takes the shape of an enormous white tiger, its features warped into something far more monstrous than any ordinary big cat.

Almost nothing is known of Byakko's mind beyond its total devotion to God and its role as a guardian. The instant it reached Earth, it set about tearing the surroundings apart.

Rated at Dragon level or above, Byakko is a Mysterious Being of staggering power, well past the usual Dragon-tier threats, and as a divine beast it is presumed to command tremendous physical strength and durability. From its mouth it can loose energy blasts strong enough to devastate wide stretches of the landscape, and it can rip open rifts between worlds to cross from the Gap in Spacetime onto Earth.

It puts these gifts to use during the Ninjas storyline. With Blast away from his post, Byakko and Genbu burst out of the Gap in Spacetime and flatten whole city blocks upon arrival. Their rampage is short-lived, as Empty Void and Blast intercept them and overwhelm both beasts with the Dimension Slash and the Giga Gravity Blow, killing them and hurling them back where they came from. Byakko holds the distinction, together with Genbu, of being among the first Mysterious Beings in the manga assigned a Dragon-or-higher rating, and its design draws on the White Tiger of the Four Symbols in Chinese astronomy.
