Plot Summary

SPOILER WARNING OF DOOM: This section or article may contain spoilers!

Following Invader protocol, Zim sends out space probes to the planet Mars to see if it has any potential use for the Irken Empire. When his probes bring back images of artificial-looking structures, he flies the Voot Cruiser to Mars with GIR in order to figure out what wiped out the "Marsoids" who built them, and determine whether it can be used by Zim to destroy Earth. After investigating, Zim stumbles upon a structure known as the Face on Mars, which turns out to be the control interface for Mars itself, which the Martians had converted into a giant spaceship, which ultimately resulted in their extinction. Zim contacts the Tallest and informs them, and the Planetary Conversion Team, of his plan, and the Irkens cheer for Zim and his efforts, only for the Tallests' praise to turn to derisive laughter after Zim signs out (the other Irkens are, surprisingly, still cheering).

After noting how his own people could cheer for him, Zim decides to use Mars to crush out life on Earth. Meanwhile, he calls the Almighty Tallest regularly to fill them in on his plan while the Tallest are busy performing the Organic Sweep on planet Blorch (which includes launching Invader Skoodge, the Invader who conquered Blorch, out of a cannon instead of Skoodge initiating the launch himself).

However, Zim's plan is discovered by Dib, who has been monitoring the Mars probe video feed on his computer. Upon discovering that Zim has taken control of Mars and begun flying it toward Earth, Dib rushes to NASAPlace in an attempt to alert the authorities. However, his efforts prove fruitless: Not only do NASAPlace's employees (having had several encounters with Dib in the past) refuse to accept his words, but he is also unable to direct their attention to their own camera feeds of Mars' surface (since they have been prohibited from even looking at the feed after not having received funding). Fortunately, a mysterious janitor at NASAPlace approaches Dib as he leaves, and offers to help him defend Earth. The janitor reveals that, prior to converting Mars into a spaceship, the Martians converted another planet: Mercury. In order to reach Mercury, the janitor allows Dib to pilot an old rocket from the days when NASA launched monkeys into space. Right as Dib is about to take off for Mercury, the janitor finally reveals himself as a fellow member of the Swollen Eyeball Network.

Meanwhile, Zim and GIR are just about to crash, Dib (now at the helm of Mercury) knocks the Irken off-course, and the
Planets 1
battle of the planets finally begins. The battle takes them to the Sun, then to Saturn, but Dib and Zim are evenly matched for most of the fight. In the end, neither Zim nor Dib are the victor; Zim tries to lose Dib in the asteroid belt, but Dib doesn't follow (thinking that going into an asteroid belt is "just stupid"), while Zim is rewarded for his rash actions by getting pummeled by asteroids. Dib would have succeeded in exposing Zim during the battle, but the video cameras he was using to record it were stolen by GIR. Zim calls the Tallest later to tell them he wanted to do a warm-up before he conquers Earth, calling himself an "unstoppable death machine." This brings gales of laughter erupting from the Tallest and other Irkens as the episode ends.

Facts of Doom


  • This episode marks the first and only time that a Swollen Eyeball agent's real identity was revealed: Agent Darkbootie, who works as a janitor at NASAPlace.
  • This episode shares the same name as an animated series from the '70s, which was a heavily edited adaptation of the anime Gatchaman.
  • This episode is a favorite of Nickelodeon's, because it actually helps the plot along, unlike other episodes.
  • In one scene, both Almighty Tallest Red and Purple talked and laughed about the time when Zim called being covered in meat. This could be a reference to one of the previous episodes entitled Germs, as was shown to the viewers that Zim came to school covered in meat at the end of that episode. However, Red says that the meat fused into Zim's skin and he almost went blind, which must have happened off-screen. This could mean that the Tallest appear to be watching his missions without Zim noticing himself.
  • This episode utilizes semi-3D animation more than any other episode.
  • This is one of three episodes with Skoodge before series cancellation. Numbered in order, they all are:
    1. The Nightmare Begins
    2. Battle of the Planets
    3. Hobo 13
  • The audio from scene where Courtney Lilly is almost crushed by Mars has become popular as a voice meme on Flipnote Hatena.
  • Gaz's voice was heard in this episode, but she wasn't physically seen in the episode. This is the same in Planet Jackers.
  • The man screaming as his Poop Cola can is being crushed by Mars is voiced by Jhonen Vasquez, and it was done in one take.

Changes & Cuts

Things You Might Have Missed

  • As the Tallest are launching the organic sweep on Blorch, you can see one of the Rat People about to eat a rabbit-like creature.
  • When the Tallest initiate the Organic Sweep, the Shuvvers laser the Irken symbol onto Blorch.
  • When they re-enter earth's atmosphere, GIR can be seen roasting a hot dog, as if the heat from the atmosphere is a campfire.
  • Mars can be seen approaching Earth when Dib's rocket splits.
  • When Skoodge gets launched onto Blorch, the Shuvvers in the background are black with red "eyes", instead of being purple with yellow-green "eyes".
  • Two Bloody GIRs are seen in this episode; one on the bottom right corner of GIR's sand face, before he puts the eyes on it, and the other on Professor Membrane's most visible foot when Dib is talking to him on his desk.
  • This is the first time that the Irkens cheer for Zim, the second is in Hobo 13. (This does not count the non-canonical game Nicktoons MLB.)

Inconsistencies and Animation Errors

Planets 2

Dib eyeing GIR.

  • When Zim drives Mars after activating the thrusters and after the scene where everybody was screaming, Zim was eating a sandwich with a Irken insignia on it. However, in the next scene, GIR had the sandwich, without the insignia on it.
  • During the scene where GIR goes to Mercury to mess with Dib, the face on Dib's shirt is missing.(also in this scene GIRs antenna changes colors twice. It turns teal after being red then turns back to red and then back to teal.)
  • When Zim launches Mars' moons (Phobos and Deimos) at Mercury, it causes a crater to appear on the front of the planet. However, the crater disappears after a few scenes.
  • Dib's rocket broke into separate parts when it flew by Zim, though it appeared to be connected together when Dib was seen on Mercury after Zim says, "You horrible interfering Dib!".
  • When Dib is flying past Zim, headed to Mercury, he appears as if he is going in the wrong direction; however, since the planets are often in varying orbits, he may have had to pass Mars to get to Mercury.
  • When Zim contacts the Almighty Tallest in his bear suit, his eyes become crooked for a moment.
  • Although it took Zim a while to get to Earth, during the battle both Dib and Zim went out as far as Saturn in no time at all. However, Zim was going at full throttle and with the boosters on during the battle, so this could be possible.
  • In the episode, Mercury was coloured grey even though the planet is brown.
  • It was impossible for GIR to take Dib's cameras; The cameras can still be seen after GIR flies away from Mercury, yet they are gone later.
  • When Zim first takes off the hood to the bear suit, his antennae are green like his skin, not black.
  • If you watch carefully, you can see Zim's PAK disappear for a moment when he is getting the data from the Mars probe.
  • When the face of Mars is transforming and GIR falls in, when Zim yells, "GIR!", his tongue is orange, the same colour as the sky.
