[[folder: The Show]]
* Zim and Dib in "Bad, Bad, Rubber Piggy". The fact that Zim brings Dib to [[spoiler:near-death]] or the fact that Dib [[spoiler: was revived and put into a badass robot to get revenge.]]
** Membrane [[spoiler: building Dib's exoskeleton in the first place to help out his "accident prone son." The guy's rarely there for his kids, but when he is, you can really tell.]]
* Zim reaches the peak of his awesome in the episode "The Wettening", where he flattens an entire city with a ''giant water balloon''.
* ''The Sad, Sad Tale of Chickenfoot'': Dib sets out to expose a hoax...and succeeds.
* Zim's very first appearance. The Tallest ''don't even have to see'' him to have the [[OhCrap crap]] scared out of them.
-->'''Red:''' That voice!
-->'''Purple:''' It can't ''be!''
** Zim nonchalantly telling the Tallest that he quit being banished when they asked why he was at the great assigning instead of Foodcourtia. That's right he QUIT being BANISHED.
* "Hobo 13" is an amazing Crowning Moment of Awesome for Zim, who not only sacrifices everyone and survives 'til the end, but even wins the last fight on his own.
** Skoodge deserves props for successfully escaping the "Ferocious Meat-Thirsty Hogulus" and being the ONLY other member of Zim's squad to not be eliminated.
* GIR gets a Moment in "GIR Goes Crazy and Stuff", delivering the following ReasonYouSuckSpeech to Zim just before he almost kills him, showing what is lying behind the CloudCuckooLander facade and why you should BewareTheNiceOnes:
-->'''GIR:''' You are no commander. You are a threat to the mission! Your methods are ''stupid''! Your progress has been ''stupid''! Your intelligence is ''stupid''! For the sake of the mission, ''you must be'' '''''terminated'''''!
** One-shot character Squidman, who [[BigDamnHeroes defeats the rampaging GIR]] after getting his "ink" back.
* Zim and Dib's battle in the episode "Battle of the Planets", which is completely literal, as they pilot ''Mars'' and ''Mercury'' respectively to fight, using the entire solar system as their battleground. Special mention also goes to Zim for catapulting ''moons'' at Dib.
* Gaz effortlessly and brutally defeating Zim's mecha in "Nanozim", thinking it was a video game the entire time. And then Dib proceeds to ''poop Zim out.''
** Earlier, Dib sneaks into Zim's base clinging to the ceiling, evades all of his security syztems, and snaps a photo. [[MundaneMadeAwesome He came in through the front door.]]
* One of the most climactic scenes in the show, how Gaz and GIR are able to sabotage Mimi by connecting GIR via SIR memory chip in "Tak, the Hideous New Girl".
** [[CrowningMomentOfFunny By dancing!]]
** From the same episode, Tak's entire plan to hollow out the earth and fill it with snacks for the Tallest. Ridiculously awesome, and it really establishes how much of a competent BadAss Tak is, especially compared to Zim.
** Also, Zim has a pretty major CMOA by beating Tak in an outer-space spaceship brawl with the ''Earth's magma'' flying around. Not only is it a CMOA for the animators, but one for both Tak and Zim for being able to maneuver and battle in it. Worth mentioning twice that ''Zim wins''.
*** A minor moment is when Zim has his voot cruiser so damaged that he has to shoot his "windshield" into space to replace it, making him completely vulnerable to the vacuum of space before the new one is up, and then goes right back into the battle like it's nothing. It's a very small moment but it's pretty awesome.
*** Also his casualness as he interrupts Tak's evil monologue to ''shoot her into deep space'' at the end of their duel. He can't even bother to do his evil laugh or listen to her in the first place because he's too busy enjoying a soda.
* Dib using a HumongousMecha to destroy Zim's equally massive rampaging nanomachine exoskeleton in "The Most Horrible Xmas Ever". This time, he ''won''.
* Another moment for Gaz would be the utter MindRape she put Iggins through after he cheated to get the last Gameslave 2. It's perhaps the one time we really see Gaz go all-out against someone, and it's both an awe-inspiring and frightening thing to witness.
** Even after being tormented the entire night over a stupid game system, Iggins still has the guts to insult Gaz to her face:
--->'''Iggins:'''"Go ahead! I'll ALWAYS be the superior gamer! ALWAYS!"
** And then he survives a fall down an elevator shaft.
* Sizz-Lorr. Even his job title is awesome.
--> ''Zim:'' My apologies my FRYLORD!
** His insanely awesome change into his "Frylord" suit (Complete with a multi-panel comic book screen moment), and then chasing after Zim mercilessly in one of the shows best chase scenes.
* Zim's speech to Dib in Bolognius Maximus.
--> "THERE IS NO CURE! And I'll never make it stop! You might as resign yourself to your meaty fate! I told you you would forever rue the day you messed with ZIM! NOW! BEGIN YOUR RUING! I'll just sit here, and watch." *Evil Laugh with "Meats of Evil" playing in the background*
* Zim signaling for GIR to fire a sandwich out of his head at Dib's head. He fires it so hard that it [[MundaneMadeAwesome sends Dib flying through the air and crashing through the wall of the nearest building]]. Zim then laughs and walks away with GIR.
* In the unfinished episode script "The Trial", it shows tons of never-before-seen footage of Zim's past, such as [[spoiler: him pointing out 5 "shmillion" errors in the entire collection of the Irken database 5 minutes after being born, escaping from an underground Irk, killing 2 former Tallest, and a montage of him blowing up planets. One of the planets blew up with ''him on it''. And it was suggested that the planet exploded because he ''scratched his butt.'' The best though is the end though, when his faulty PAK is being drained of all data by the Control Brains. However, the filtered data is so completely horrible that the Control Brains malfunction and title Zim as the greatest Irken ever!]]
** Rodger Bumpass voicing the Control Brains. It has to be heard to be believed. He manages to give a voice so deep and ominous that you'd think it was machine altered. He caused the audience to gasp in awe.
* Everything that happens after Gaz gets cursed with pork tongue in "Gaz, Taster Of Pork." After seeing this evil bitch threaten to ''feed her brother to flesh eating dolls'', her long, well-deserved HumiliationConga is immensely cathartic.
* Dib's wonderful life of doom. He fights off a swarm of fighters in space, tears apart the Irken flagship with his bare hands, jumps off, gliding into the atmosphere all the way to the ground, riding a stream of lightning, lands perfectly, accepts the greatest person to ever live award before off-handedly blocking the debris of the flagship.
** Except when you get to the end and it was [[AllJustADream a big middle finger to Dib's delusions of grandeur]]. Zim then uses a cannon to shoot a muffin at Dib and [[EvilLaugh laughs maniacally]].
* Keef in "Bestest friend." Not only does the kid survive all the torture Zim puts him through, from electrocution to having his freaking eyes ripped out...but he never once loses his cheerful, sunny demeanour, and continues trying to make friends with Zim in an unproduced episode!
* Skoodge gets an offscreen MomentOfAwesome when he conquers an entire planet of voracious alien rodents.
* When GIR rescues Zim from the Saucer Morons. It's the only time he's been (semi) competent without being in duty mode.
* Dib is sneaking into Zim's house with an invisibility suit. GIR somehow manages to detect him and splash him with a soda, shorting out his suit and exposing him.
* Tallest Red gets his turn in "Backseat Drivers from Beyond the Stars," when Zim takes over the Massive and proceeds to drag the thing to Earth through several planets and a ''star.'' While Purple is panicking and wolfing down donuts, Red runs a manual check and discovers that Zim has remotely latched onto the power core. He then swaps cores with the Resisty ship that's been taking potshots at them the whole episode, thus regaining control. This, from one of the two figureheads who demand [[BrilliantButLazy reports be given as puppet shows.]]
* A meta one for the fans: getting the main four of the voice cast as well as various production people to come to the first [=InvaderCon=], even more for the second convention and ''Jhonen Vasquez himself'', who hates traveling far for conventions. Icing on the cake for Invadercon II was the letter writing campaign to get the show back and a sneak preview of a fan animation team's production of Mopiness of Doom.
** And now, after so many years, the show is FINALLY being officially revived in the form of a comic series. The fans who worked so hard in keeping this series alive and demanding its return really deserve some credit here.
* In "Plague of Babies", an army of evil alien babies invade Zim's home to take his ship. Zim proceeds to stay one step ahead of them, and quickly comes up with a plan to take them down at the last moment. It's awesome for showing that when Zim isn't given time to allow his ego to interfere with his decisions, he's actually a capable and dangerous opponent.
* In the unproduced episode "The Trial", GIR conquers the earth ''on his own''.
* Zim's BigDamnHeroes moment in "Halloween Spectacular of Spooky Doom" when he rescues Dib from the Halloweenies by bursting through the window in a giant mecha stolen from Nightmare!Membrane that is scary enough to make all the Halloweenies back off.
[[folder: The Comic]]
* Issues 1-2 show that Zim can be frighteningly clever when he needs, if only for petty needs. He turns Dib's ChronicHeroSyndrome against him, by going into hiding and counting on Dib doing nothing but obsessively waiting for him to come back. This leads to Dib being practically immobilized by obesity. Zim then tracks down the Gargantis Array and [[spoiler: broadcasts footage both of Dib's disgusting form and his subsequent comeback workout, humiliating him across the universe.]]
** Dib gets his moments during this as well. First, there's his epic comeback workout montage, and then the dogfight between Tak's ship (which he's piloting) and Zim's Voot, which he [[CurbStompBattle utterly owns]], blowing the Invader out of the sky.
* Issue 3 has Zim pull off another plan surprisingly easily, taking over the art world and using it to enact his plan to summon the Star Donkey.
* Issue 4: If nothing else, you have to admire [[TheDeterminator everything Zim goes through]] for the sake of (he thinks) powering up a super weapon the Tallest have given him.
* In Issue 7, Zim needs to recover the Voot from the mutant lady bug monsters that have stolen it, and [[http://sa6044.deviantart.com/art/Zim-And-Gir-On-Giant-Slug-589999111 this is how he does it.]]
* In Issue 8, ''Dib scores a victory and nothing bad happens to him.'' Which may not sound like much, but [[TraumaCongaLine given how things usually are for him and what has already happened to him in the comic...]]
** The climatic fight between Dib (in the Overtrouser) and Zim (in a pair of mecha pants) just looks ridiculously awesome.
*** The fight apparently lasted ''14 hours!''
** Likewise, the ImagineSpot Groyna has of a comic based on her and Dib having adventures as "pants hunters" looks amazing.
