Tyranno Hassleberry
 is a character from Yu-Gi-Oh GX. He is one of Jaden's best friends. Hassleberry once had an accident while on looking for Dinosaur fossils, when a rock side came down and broke his leg in two, luckily, he found a prehistoric fossil before the event, and used the bone to save his leg. Afterwards, Hassleberry had acquired Dinosaur DNA in his blood, allowing his eyes to go prehistoric when ever he needed to, in other words, Hassleberry, is half human, and half dinosaur. Speaking of Dinosaurs, Hassleberry's Deck is themed after Dinosaurs, with his Aces being Black Tyranno, Ultimate Tyranno, and Super Conductor Tyranno.[[Category:Tino's Adventures allies]
