He is the leader of the Dino fairies, he is bossy, demanding, and gluttonous, but he also genuinely cares and is very loyal to his friends. He is brave enough to fight or to protect his friends. His hobbies are watching TV, reading mangas (comic books in the English version) or magazines of pretty women, playing video games, singin and dancing to music, and eating. He is somewhat egomaniac, obsessing over his "coolness" and his species' reputation as "King of the Dinosaurs" and is seen bragging about himself. He is attracted to attractive girls and women even to a point of flirting with them (he also falls into the trope All Men are Perverts). He also has a brother-sister like relationship with Clover the Triceratops fairy and they usually argue or compete with each other (a reference to the rivalry of T-Rex and Triceratops) but they do really care and are very loyal to each other (There relationship is similar to Leonardo and Raphael from TMNT and Sailor Moon and Sailor Mars from Sailor Moon). His personality is inspired by Kero from Cardcaptors and somewhat of Keroro from Sgt. Frog. He is partnered with the leader of the Pretty Cure.
