    Ryan Reynolds assembles a team of "Superzeroes", apparently-pathetic animals with unexpectedly awesome superpowers. Forget about the cheetah's speed, the eagle's eyesight or the elephant's brute strength, and say hello to the invisible glass frog, the indestructible honey badger and the pistol shrimp who can fire bubbles that are as hot as the surface of the sun.

  • S01E02 Terrible Parents

    • National Geographic

    Ryan Reynolds reveals some highly questionable parenting strategies from the animal kingdom’s worst parents, the underdogs. From a goose who lays their eggs on the top of a cliff to a koala that feeds its baby poop, it’s uncertain if they are bad parents or just misunderstood. But no matter how bad you think you may be at parenting; you can’t be as bad as these guys.

  • S01E03 Sexy Beasts

    • National Geographic

    Forget the birds and the bees, Ryan reveals the steps to finding ‘the one’, Underdog-style. From ‘first attraction’ in giant-nosed proboscis monkeys to the importance of wingmen in turkey courtship to foreplay in flying foxes, these guys have re-written the rule book on messy and complicated relationships.

  • S01E04 The Unusual Suspects

    • June 22, 2025
    • National Geographic

    Ryan Reynolds puts the spotlight on the underdogs who get ahead by sneaky tactics. From the master-of-disguise frogfish to a butt-biting jackal and a multi headed caterpillar playing the decoy, these are the masters of deception and deceit. And bringing all these hustlers together is the greatest con artist of them all – a cunning macaque who feeds on the spoils from unsuspecting tourists.

  • S01E05 Total Grossout

    • June 29, 2025
    • National Geographic

    Ryan gives his unique take on the animals who use gross-out tactics to achieve their goals, from defending their home to finding a mate, and win at the game of life. His cast includes manatees who use flatulence to control their buoyancy and cave dwelling fungus gnats that create beautiful, illuminated fly-traps from the mucus lit by their bioluminescent butts.
