Pinocchio, the 12th strongest Knight and the smallest among them, was originally a marionette created by Diana for her younger sister Dorothy when Dorothy was a child. He came to life after joining the Chess Pieces. During the 6th round, he was instructed to defeat Dorothy if he wanted to become human. Similar to his namesake, his nose grows whenever he lies, and after about three lies, it transforms into a cannon that he can use to attack his opponents.
In the War Games at the Mushroom Field, Pinocchio was torn apart by Dorothy's ÄRM Toto. By the end of the 6th Round, his remains were salvaged by Chaton. In a filler episode, he was rebuilt with wagon wheels. Alongside Kouga and Girom, they ambushed Dorothy, Ginta, and Alviss, during which Pinocchio destroyed Dorothy's Andarta while Babbo sustained damage. After being repelled, Diana sent them to capture Caldia's Grand Elder, but they were defeated by Dorothy and Ginta. In the anime, they were last seen riding on Kouga's Kung Fu Frog. Pinocchio is a Weapon ÄRM user.
