The Resisty is a group of aliens led by a Vortian (flying a Vort ship) who have chosen to resist the mighty Irken Empire. They show up in the episode Backseat Drivers from Beyond the Stars.
If you think that Resisty is a poor name for the group, you would agree with their leader. Unfortunately, they're committed to it now, though, so you have to hope they make the best of it. And it IS better than The Pirate Monkeys.
Their initial foray into resistance was poorly planned but really went better than I think they expected.
They made contact with the Almighty Tallest (who denigrated their name too) and right as the Massive is about to vaporize them Zim takes remote control of it and begins trying to fly it to Earth. Of course, while Zim is in control the Irkens are unable to fight back, leaving the Resisty with an incredible opportunity. They use this opportunity to try to blow a hole into the snack storage compartment, but even though they blast away while chasing the Irkens accross the universe (and directly through a star) they never manage to liberate the snacks which they hoped would "feed the revolution."
They DID manage to put some nice graffiti on the back of the Massive, though. Resisty Rocks!
Eventually, though, the Irkens figured out that Zim was controlling their ship through the power core and they first stole the power core from the Resisty ship and then beamed their compromised power core into the Resisty's ship. With their new remotely controlled power core flying them to Earth (where Zim was going to land the Massive on Dib's head) the Resisty abandon their ship and activate the Shrinky Self-Destruct module.
The Resisty members DO escape in pods, though, and we see them again as customers in The Frycook what came from All that Space.
And now for the members
Lard-Narr
A Vortian, leader of the resistance and captain/commander of the resisty's ship, Lard-Narr plans to keep the resistance alive until it has grown large enough to tackle the Irkens. He is quick to panic, but won't give up, even when faced with the most difficult challenges.
He seems to be adverse to changing his plans: even when The Massive was rendered defenseless, he sticks with his original plan of stealing snacks, despite the fact that this was a prime opportunity to do some serious damage
Shloonktapooxis
Second in command and in charge of firing the laser weapon, Shloonktapooxis is an important member of the resistance. His appearance is that of a floating purple cone with a curled antennae. His suggestion for the resistance's name was 'The Pirate Monkeys'. His own name is a joke directed at the unpronounceable names commonly found in sci-fi shows. the authorities are unshure to labe him as robot or alien
Spleenk
An incredibly stupid member of the resisity. He is full of bad ideas, such as attacking Massive and naming the resistance "the Resisty", that Lard-Narr uses for some reason. When under stress he seems to have a seizure.
Unknown Member #1
This member of the Resisty is a little green blob who vomits all over herself all the time. She looks similar to the mascot of the restaurant Shloogorgh's Flavor Monster, and thus is possibly from the same species.
Unknown Member #2
This member of the Resisty has 3 heads. He set the blob creature upright after it fell over. Based on the designs of the scientists for the unfinished episode The Trial, the three-headed alien might have worked as a scientist with Lard Nar on Vort.
Unknown Member #3
This member of the Resisty is an armless, insectoid alien with 4 legs and horn that protrudes from his chin like a goatee
Ixane
This alien wears a cloak that obscures what it looks like. She is the only other female member of the Resisty.
Unknown Member #5
One of the races to join up with the Resisty is a species with a dented head on a long neck. This race can also be seen on Foodcourtia. It looks like it is adistorted Irken which may mean this Alien is the Smeet that Zim shoved up the chute in the unfinished episode The Trial.
Unknown Member #6
This alien lacks a head, but has its brain floating where its head would be.
Unknown members 7 & 8
These members seem as though they are not aliens at all, but robots. They hover instead of walking
Several Unknown Members
There are a good deal of this type of alien on the Resisty ship. Spleenk pushes through the crowd of them whenever he has something to say.
Unknown Member #9
Gray-coloured aliens with large heads that resemble toenails. There are several of them working consoles aboard the ship, including the Shrinky Self-Destruct.
