Bio/Desc/Personality: As a human Ujauja had lived a miserable life of jealousy and spite. In the end his stubborn envy was what did him in. Even after that, when he was so jealous of the Shinigami's powers he attacked the one person who could have granted him salvation. The shocked death god left him to his own devices instead. Not undeserved.
So Ujauja became a hollow, but not just that. A very good hollow.
He was exceptional when it came to plotting, trapping and stealing the life force of the helpless virtuous little souls waiting for their ticket up. Nothing in life had ever come this easy to him. The irony wasn't lost on him. After decades envy started to make place for gluttony. Every meal far from the other, and ever watchfull, Ujauja had managed to crawl under the radar for so long.
He'd eaten so much... So much he forgot himself. As his power grew his senses disappeared.
Soon he was walking with the hordes of the Gillian. The next part is vague and dull. One of the many, barely a thought. This went on for decades...till now.

Release Form/Description/Spell:  Ujauja's Zanpakuto takes the shape of a slender curved dagger, it's sting delivers a potent poison that drains reiyoku.
Upon his release Ujauja shatters into a large swarm of locust.
The locust have a heightened speed of reproduction with a single individual living an entire lifespan in a few seconds. You'll never see the same bug twice. Given enough room the swarm will rapidly devour everything edible in sight. And the creatures eat only reiyoku.
While the individual vermin are mindless drones that eat, the swarm moves with purpose and cunning. At the heart of the swarm lies evil.

Abilities:
Cero: standard issue, blight yellow
Sonido: standard issue, talented, works in release form but instead of choosing one direction every bug is send elsewhere, scattering over a large environment.
Survival of the Fittest: Ujauja's very blueprints shift constantly, but not just growing stronger, like every hollow. He changes laterally as well. Constantly shifting aspects of his genetic make-up.
His body automatically adjusts to it's environments. Ranging from heat resistance to breathing under water or in a poison cloud, his body adapts to the ideal surviving conditions in any situation.
In release form the changes happen faster and more drastically.
