Zucchinitz had the tip of his tail cut off when he was little, robbing him of the power to transform during a full moon. His father found him during his work at the recycling center. Passing by a freezer, he heard the cries of a baby, these cries literally made the container vibrate. With his wife, he decided to adopt the baby after 6 months of searching for his biological parents. Zucchinitz runs a small boxing club in a poor Satoshicity neighborhood. He tries to educate young people in difficulty in the art of combat. He was one of the best fighters in the world until he vanished after losing his two children.
