Baku

The Baku is an enormous chimera shaped much like an elephant, its bulk great enough to make Sasuke Uchiha's Susanoo look small. Dark orange covers most of it, apart from the trunk, the legs, and the patches ringing its eyes. Tiger-like stripes run across its feet, great tusks jut from its mouth, and a beard-like growth hangs beneath long, keen claws. Cloth binds its head, and plated armour sits where the trunk meets its face.

Folklore holds that the beast feeds on dreams and nightmares, a notion Tobi recalled on seeing it. Its true weapon is its breath: gaping its jaws to inhale, it drags in everything nearby with overwhelming pull while venting the intake back out through its trunk, wholly untroubled by the debris it takes in. Danzō combined that suction with his own Wind Release to magnify the attacks, enough to pin Sasuke's Susanoo in place and tear through its guard. The same pull, however, feeds Fire Release just as readily, a weakness that can be turned against the creature.

Facing Sasuke on the Samurai Bridge, Danzō called the Baku forth to unsettle his enemy's Susanoo with its suction. Riding that same force, he powered up his Vacuum Serial Waves and gouged a gap in the armour, opening a path to strike Sasuke head on. The Uchiha turned the tactic around, hurling a fireball straight into the Baku's open mouth; the suction only swelled the flames, driving the beast to withdraw.
