When the Constructicons begin mining on a distant asteroid, Optimus Prime calls on Omega Supreme for assistance, only for a long-standing enmity between Omega and the villains to come to light.
A rocket ship bursts out of the ocean and travels into space. Guided by an unknown force, the rocket lands on an asteroid and then directs that hunk of rock into Earth orbit. A door on the rocket opens, revealing the Constructicons, who step out and signal Megatron of their success. The Decepticon leader intends to mine the asteroid for the energy-rich ore inside.
During his own orbit of the Earth, Cosmos catches sight of the operation and reports in to Autobot headquarters. Optimus Prime contacts Omega Supreme for help. During a one-on-one chat, Optimus senses that Omega is holding a grudge against the Constructicons and demands an explanation. Omega complies in normal speech.
On Cybertron, Omega Supreme is a good-natured, friendly Guardian Robot. One of his assignments is guarding the Crystal City, the creation of his friends, the Constructicons. Unfortunately, they are altered by Megatron's Robo-Smasher and permanently changed into Decepticons. The Constructicons then trick Omega into leaving his post, and during his absence, they destroy the city. After losing his friends, his job and his city all in the same day, Omega swears he will first help his friends recover and then will get vengeance on Megatron.
For weeks, Omega tracks the Constructicons, until he captures them and tries to reprogram them. At first, it appears that they have been restored, but on their way home, the Robo-Smasher corners them. The Constructicons form Devastator and wrestle Omega into the Robo-Smasher's clutches. The machine goes to work at reprogramming Omega; he is able to pull away in the middle of the process, but the experience leaves him scarred and emotionally barren except for his desire for vengeance against his former friends. He chases after them for millions of years and finally finds them on Earth.
Knowing that Omega's judgement might be clouded fighting the Constructicons, Optimus orders him to remain on Earth unless Prime himself gives the order to head to the asteroid. Omega acknowledges Prime's order.
In space, Cosmos gets a sample of the ore from the asteroid and brings it back to headquarters. Teletraan I determines that the ore is organic in nature. Prime has just ordered Omega to destroy the asteroid, and now he's regretting that decision. His further attempts to contact Omega fail because the huge Autobot is bent on revenge.
Once on the asteroid, the vengeful Omega immediately attacks his enemies, wildly smashing open a huge fissure. The entire asteroid breaks in two like an egg, hatching an alien creature, which flies toward Earth. (Although it appears somewhat robotic, Teletraan I's claims that the asteroid was organic in nature imply that the creature is, in fact, biological.)
The creature heads straight toward Earth and begins to destroy San Francisco. Powerglide, Ironhide, Smokescreen, Tracks and Beachcomber move to stop it, but fail after several attempts.
Omega is still attacking the Constructicons when Prime tracks him down. He demands that Omega stop his attack and instead clean up the mess he created by releasing the creature. Prime tells Omega that only he can save Earth by luring the monster back to its food supply on the asteroid. When the Constructicons escape, Omega threatens Optimus, but the Autobot leader refuses to back down and reminds Omega of his past.
Finally, Omega concedes to Prime's authority and heads off. He confronts the creature and leads it back to the asteroid, where it eats its fill and then flies off into space, never to be seen again.
In the meantime, Prime uncovers Megatron's ore-processing facility and singlehandedly destroys it.
At the end of the day, Optimus thanks Omega for fulfilling his duty. Both Optimus and Omega express hope that he might one day regain some of the feelings that he lost.

"Where are you going?"
"To talk to the only other Autobot who can fly into space."
"Omega Supreme! Sounds like a barrel of laughs."
- —Powerglide and Optimus Prime
"That asteroid may be new fuel for Megatron. The Constructicons are mining—"
"Constructicons?! Constructicons: enemies. Enemies die!"
"This is a military mission, not a vendetta, Omega."
"I want to know what happened between you and the Constructicons."
"Talk: irrelevant. Answer: private."
"I want to know about it."
"Order: received. Will talk."
- —Optimus Prime and Omega Supreme as Omega begins to read his diary out-loud.
"Quit squirming! This is for your own good! HAHAHAHHAHAHAH!"
- —Devastator mocks Omega Supreme with Omega's own words while holding him down for the Robo-Smasher to reprogram him.
"Megatron failed. I lived...but changed. Since then, I feel only hatred for the Constructicons."
- —Omega Supreme reveals the results of his betrayal to Prime.
"Revenge: soon. Anticipation: high. Vengeance: GOOD!"
- —Omega Supreme after being ordered to remove the Constructicons from the asteroid in orbit of the planet. He is clearly excited.
"Well, old friend, that Robo-Smasher certainly gave you a mean streak. Too bad it didn't finish the job!"
- —Scrapper as the Constructicons meet Omega Supreme for the first time since the betrayal.
"What—eh—if we all just split up?"

Animation and/or technical glitches
- Near the beginning of the episode, when Hook is talking to Megatron, Sideswipe (an Autobot) is standing to his right. When the camera angle switches, he is replaced by Soundwave.
- While being attacked by the Robo-Smasher, Omega Supreme's left upper arm and elbow disappear, making it look like his blaster arm is floating in air.
- At several points throughout the course of the episode, the Constructicons are shown standing or walking as a group of only five members, with one of the six members erroneously omitted.
- When Megatron is testing the ore, Hook is shown with him even through the Constructicons are on the asteroid at the time.
- "The Secret of Omega Supreme" established an important (and contentious) second origin story for the Constructicons. According to Omega Supreme, millions of years ago, when he was the guardian of Crystal City on Cybertron, he befriended the then-benevolent Constructicons. Megatron subsequently rewrote the Constructicons' brainwaves, turning them into a combining force for evil. This story contradicts Megatron's assertion (in "Heavy Metal War") that the Constructicons were built "recently" on Earth. However, he might have been referring to their current bodies, akin to what happened with the Combaticons, so this account of their origin isn't entirely invalid.
- Regardless, the Constructicons' origin is complicated by a flashback in "Five Faces of Darkness, Part 4" in which the Constructicons are shown creating Megatron, which contradicts both previous origin stories.
- These different origins for the Constructicons have become notorious as one of the biggest continuity errors in the series.
- The Constructicons are shown on Cybertron with their current Earthen alternate modes, millions of years before any of those vehicles ever existed. However, since this was a flashback that was told with no visuals for Optimus Prime to see it just means that the animators decided to go with the already familiar look, instead of going with new transformations for the Constructicons.
- Also, the Constructicons have Decepticon symbols before being turned evil.
- Optimus Prime refers to Omega Supreme as the only other Autobot capable of spaceflight, yet in season one, Skyfire/Jetfire made at least one interplanetary flight to Cybertron when it was in Earth's orbit in "The Ultimate Doom, Part 2". However, this could be due to the fact that Cybertron had been moved much closer to the Earth.
- According to both Omega Supreme and Optimus Prime, the reprogramming effects of Megatron's Robo-Smasher can never be reversed, but in "The Core", Wheeljack and Chip Chase were able to sway the Constructicons to the Autobots' side with Dominator Discs. This may have been yet another brainwash/override of previous programming rather than a "reversal", as such.
- Optimus Prime's surprise at Omega Supreme's post and function (MOS) back on Cybertron doesn't make sense, considering he had been given the Matrix and thus the rank of Autobot Commander about three million years before Omega's encounter with the Robo-Smasher.
- As noted, the creature that hatches from the "organic" egg is clearly made of metal.
- San Francisco
- Why Omega Supreme is different from a Guardian Robot (such as being sentient, unique coloration) is unknown.
