Underdogs | Official Trailer - Ryan Reynolds

Check out the Official Trailer for Underdogs, a new nature series dedicated to the animals that aren't quite at the top of the food chain, distributed by National Geographic.

Each episode of the five-part series showcases a different aspect of these underdogs’ bizarre mating strategies, surprising superpowers, deception, dubious parenting skills, and gross-out behaviors. Underdogs features a range of never-before-filmed scenes, including the first time a film crew has ever entered a special cave in New Zealand - a huge cavern that glows brighter than a bachelor pad under a black light thanks to the glowing butts of millions of mucus-coated grubs. All over the world, overlooked superstars like this are out there 24/7, giving it maximum effort and keeping the natural world in working order for all those showboating polar bears, sharks, and gorillas.

Underdogs is narrated by Ryan Reynolds.

Underdogs premieres on June 15 on simulcast on ABC, and will be available to stream the next day on Disney+ and Hulu.
