Alpacacino is a bazooka that "ate" an unnamed ZoanDevil Fruit, allowing him to turn into a white alpaca with a metal band around his neck (a circular ring is attached to this) and his full body. His eyes turn red when he is taking his cannon position. He also has a purple crank on his left side. In his hybrid form, he also shows the handle of a bazooka.
He seems to have a good relationship with Shuzo, and nods to him whenever he agrees with him. The only one notable time he is in disagreement with his master is when Shuzo reveals to Momonga the existence of Neo Marines and Zephyr's return.
Alpacacino is shown to be capable of using Busoshoku Haki to increase the destructive power of his cannonballs. By imbuing them with this power, they can damage a Devil Fruit user like Luffy, since with Busoshoku, it can hit his substantial body.
