Dile is a tertranadon and Juju's pet. He has green and black scales and orange eyes. Unlike others of his species, he doesn't have an enlarged throat pouch.
While in the Monster Hunter universe, the team comes across a fighting arena created by hunters. They infiltrate the arena by putting their own rescued beasts into the fights. They all only pretend to fight each other to give the others time to rescue the trapped beasts. Juju rescues Dile and he's grateful.
Dile is a playful, carefree, and somewhat immature beast, noted by Juju when she remarked, that she had never seen a croc so playful. However, he is not as reckless as his friends and still respects rules. He is quite rebellious like his master but he quickly obeys his master's commands. He has the attitude of a good teammate, working together with his friends to save their masters from Nefarious.
Dile can inflate his belly and stomp on enemies. However, he is more sluggish and slow in this state.
Trivia:
Dile gets his name from him looking like a crocodile.
Juju mistakes Dile as a crocodile upon their first meeting.
