Gavin

Gavin (voiced by Nick Offerman) is a misguided Dino-Bird who proudly trained his kids the fine art of stealing eggs. But after being repeatedly thwarted by Buck, the family embarks on a mission to rid the Ice Age World of their weasel- arch nemesis. Gavin is the main antagonist of Ice Age: Collision Course but he reconciled with Buck and the herd to stop the asteroid.

Personality & Traits
Gavin is a brave and tough Dino-Bird that loved his children. However, his ruthlessness often keeps him from thinking clearly as he was more concerned on getting revenge on Buck than helping the herd stop the asteroid. With some convincing from his children, however, Gavin spares the weasel's life so they could save the planet.

Gavin has teal-blue scales with a gray underbelly and red feathers. He has greenish yellow eyes and a black beak, with scuffs and scratches at the tip.
