Henzo has an old droopy appearance with droop eyes, a large mustache that covers his mouth and a grey bowl cut. His face is also rather wrinkly. He wears a button down shirt that has a read collar. The rest of it is lavendar with lots of pink shapes decorating it. Over that he wears a long white coat with two pockets.
He lost his childhood friends Rapanui Pasqua, Isoka, Akibi, Rongo and Pukau due to a pirate invasion by Wetton 50 years ago, and his attack knocking the pirate captain off of the ship that was heading into the Rainbow Mist.
During the Rainbow Mist Arc, he helps propel his friends from the Rainbow Mist to the time period 50 years ago, with the help of the Straw Hat Pirates.
He rides a boat that he designed called the H-1.
