Alpacacino is a animal partner of Shuzo in the Neo Marines.
Alpacacino is an antagonist in the One Piece series that was created by Eiichiro Oda. He's an anime filler character that made no appearance in the original manga that was the inspiration for the anime. The One Piece anime series first began airing in October 1999, and Shuzo wouldn't appear until the Z's Ambition Arc that began in Episode 575. These episodes directly tied into the twelfth film of the One Piece series, One Piece Film: Z.
His first anime appearance was in One Piece - Episode 575 "Z's Ambition! Lily the Little Giant!". His character in the Japanese series is voiced by Rumi Kasahara, and the U.S. dub produced by FUNimation has yet to announce a voice actor.
