Hookocho was an evil alien warlord who appeared as the main villain in the episode Jeepers, Creepers, Where Is Peepers?.


Hookocho was a tall cyan-skinned humanoid alien with long messy blue hair, elfish ears, and visible canine teeth/fangs when he opened his mouth. He wore golden armor with three spikes on either shoulder and two red gems on the case, a red cape, and white tights with black boots and black gloves set with two red gems.


Electrokinesis: Hookocho has the power to create, shape, and manipulate electricity, which he channeled through his hands, and it manifests as either blue or red beams that could melt objects (i.e. a bomb) and shock living beings (he electrocuted Dexter and Koosy).


Hookocho is a power hungry and cruel tyrant who will happily destroy anything that stands in his way of galactic domination.

Little is known about Hookocho, save that he is an evil alien warlord who came to Koosland to abduct its guardian, Peepers, for the purpose of absorbing his limitless power to energize his space fortress' secret weapon, designed for one purpose: to erase Dee Dee's world from the face of Imagination and use his newly enhanced powers to rule the Galaxy.

However, his plans are foiled by the efforts of Dexter and Koosy. But Hookocho's ultimate demise can be contributed to Peepers, the hatred mutating him into a flesh-toned dragon and promptly stomping and squashing Hookocho, just as the elven maledict is busy tormenting Dexter and Koosalagoopagoop.


  • "Hush now Peepers. No one can hear you, no one can save you and with your help, Planet Koos will be destroyed."
  • "Shut up, And get to work!"
  • "Goodbye Planet Koos. Goodbye forever! HAHAHAHAHAHAHAHA!"
  • "Well, well. Looks like we got visitors, Peepers. Lets give them a warm welcome, shall we?"
  • "Well, well, well gentlemen, I applaud your courage and heartfelt attempt to destroy me and my cause. But you see, no one has ever defeated Hookocho, The Prince of Pain and Misery. Now prepare yourself for complete and total annihilation. My powers as of now are far superior then all the power through out the universe. And when the reversal of Peepers' power is complete, I will equal to no other, and all will perish who defy me. Prepare for a new dawn, gentlemen. And in just a few moments, you will be the first to kneel before your new king, King Hookocho!"
  • "You insignificant TWERPS!"
  • "Goodbye!"
  • "Well, well, well. Now you really tick me off!"
  • "Shoot." (last words)


  • Hookocho was a mixture of a bishonen anime character and the villain from Labyrinth, Jareth.
    • Hookocho also bears resemblance to Blackhorn, the main villain of the NES game Astyanax.
      • Peepers turning into a dragon and defeating Hookocho may also be a reference to Blackhorn's final form being a dragon.
  • His name was often misspelled "Hookochu", but it was actually spelled "Hookocho" in the ending credits of this episode.
  • Hookocho's past and exact nature were unknown, as it was never mentioned or confirmed if he was a real being, or an imaginary entity, or how he came to Koosland. One possibility was that he might have been one of Dee Dee's rogue creations. Another might be that Koosland might actually exist somewhere in the real universe, or the universe Koosland is in is also host to other imaginary worlds created by children, and Hookocho might have come from one of them.
