Vortian Prisoner 777 is a Vortian prisoner held on the now-conquered Planet Vort (though he is later transferred from Vort to Moo-Ping 10 sometime before the events in the Invader Zim comic Issue 1). It is presumed that he lost his freedom when the Irkens conquered Vort sometime before "Backseat Drivers from Beyond the Stars".

Like the rest of his species, Prisoner 777 helped design and engineer many of the weapons and vehicles used by the Irken Empire. He is also partially responsible for the designing of The Massive. Zim gets many of his gadgets from him, as well as the schematics for the Massive's remote command chair. He made his first and only televised appearance in "Backseat Drivers From Beyond the Stars", but would also have appeared in the unfinished episode "Nubs of Doom", and given Zim a top-secret experimental Vortian doomsday device to be built inside Minimoose. Inexplicably, his voice is much more nasal in the voice recording for that episode, apparently having been provided by David Herman, instead of Wally Wingert.

Prisoner 777's debut appearance

Vortian Prisoner 777 later appeared in Issue 1 of the Invader Zim comic series, where it is revealed that he is only handing Zim information to prevent the Irken from erasing his children from existence. Zim wanted to know the location of the Gargantis Array, but 777 did not know where it was. Instead, he told Zim that there was a Xliactian Historian who knew the location of it, but she went into hiding.

Facts of Doom

  • His prisoner number is a reference to Johnny the Homicidal Maniac; the main character, Nny, lives in house number 777.
  • Oddly, 777's eye color changes from light red on the show to light blue in the comics. Whether this is a permanent change or a temporary error (as something similar also happened with Dib in the first issue) is currently unknown, given that he hasn't shown up again since.
