Will you forget the head slicing thing?!
~ Philoctetes yelling at Hercules to stop beheading the Hydra.

The Hydra is a giant dragon-like monster that appeared as a minor antagonist in Disney's 35th full-length animated feature film, Hercules. It is based off the original Hydra, a monster that fought the original Hercules in the mythical Greek legend.

Its vocal effects were provided by Frank Welker, who also voiced other characters such as Scooby-Doo in the Scooby Doo franchise, Jabberjaw in thr Jabberjaw TV franchise, Doctor Claw in the Inspector Gadgets TV franchise, the Cave of Wonders in Disney's Aladdin, The Trolls in Willow and the Spiders in Eight Legged Freaks.



Ph-Ph-Phil what you call that thing? TWO WORDS, AM-SCRAY!
~ Hercules and Philoctetes.

The Hydra was once a minion of Hades who was commanded to kill Hercules and it's the first obstacle after Hercules lifts the boulder to free the boys but they turn out to be Pain & Panic. In the epic battle, when it swallows Hercules, Hercules cuts off the Hydra's head by slicing at its throat from within.

However The Hydra was not dead yet, and three more heads grew in its place. Hercules continued to cut off the heads in a vain attempt to kill the Hydra. Apparently, it was a jungle of heads, and Hercules seemed to be unable to kill it. Eventually, Hercules came up with a plan, and tricked the Hydra. He let it grab him with its claw and pin him to the side of a cliff, intent on delivering a killing blow. At just the right moment, Hercules used his immense strength to deal a powerful punch to the cliff. This fractured apart the cliff enough to cause an avalanche of rocks to pour down as a massive rockslide. This rockslide crushed the Hydra, killing it permanently.

Hercules: The Animated Series

Phil, I need a sword! Find me a sword! Kid, the last thing you used to defeat the Hydra is a sword. You got enough mouths to feed already! What am I supposed to do?! Remember why you here: fight your fear, not The Hydra!
~ Hercules and Philoctetes when they realized it was Phantasos as seen in Hercules and The Long Nightmare.

  • The Hydra is based on the Lernaean Hydra, a serpent-like water monster of Greek mythology. It originally had nine heads, one of which was believed to be immortal, that would replace each other in the same manner as the Hydra in Hercules, and was killed by Heracules as the second part of his twelve Labors after the Nemean Lion.
    • As stated in the myth, Hercules slew the Hydra by slicing off its heads, then using a torch to cauterize the stumps left. The immortal head was sliced off like the others, and was buried under a rock.
  • The Hydra is rendered in CGI, unlike the rest of the movie which is in hand-drawn animation. This was done as it would have been incredibly difficult to draw each head individually.
  • In Once Upon a Time, the Hydra does not appear. However, when Hercules tells his twelve labors to a teenage Snow White, one of his medals represents the creature.
  • The Hydra is similar to Sammael from the 2004 live action film, Hellboy, as they have the ability to regenerate, though they can still be killed with the proper methods.
  • According to the Disney Read-Along story of Hercules, the Hydra grew a total of 30 heads.
    • However, the math shows if Hercules removed one head and three more were added up to 14 times, the result would be 29.
  • According to Greek mythology, the Hydra is the offsprings and daughter of Echinda and Typhon.
  • In Hercules: The Animated Series, instead of an adult The Hydra was a baby and one of Echinda's children just like its brother, Cerberus.
