Coop finds an alien robot in a Jersey City junkyard, and decides to soup it up with hot-rod parts and flame decals. What happens when the original owner of this robot sees Coop's improvements?

Coop, Jaime and Kiva discover an ancient Ringworld filled with energy-loving worms.

After racking up multiple driving violations, Coop has to spend the day at the DMV to get Megas out of impound.

Coop quests for a slushie on a hot day in the city; however, every store he visits gets destroyed before he can get his frozen treat.

Coop begins a bad day by accidentally creating a giant cheese monster and has to stop it, but the method he uses gets cheese in Megas's CPU core. Unaware of this, Coop enters Megas in an auto show, and is putting up a very good showing until Megas breaks down and nearly destroys the building. Fortunately, he's able to stop it, but now the Glorft see an opening to attack and invade the city, hoping to capture Megas. But first they need to find the CPU core.

In order to impress a girl, Jamie borrows Coop's car to take her for a ride. Unfortunately, Warmaster Gorrath arrives piloting a deadly replica of Megas (dubbed Mecha-Megas) who's destroying Jersey searching for Megas; naturally, everyone thinks that the fake is just Coop being destructive. So Coop must use his secondary command bridge to control Megas. However, this method is much more difficult, so Coop does rather badly. Even worse, Jamie accidentally activates the car's connection to Megas, so now he's in control of Megas, but he has no idea - he's just trying to have a date.

The S-Force erroneously attack Coop because they believe he is an evil-doer intent on destroying the Earth; to complicate matters, Coop is aided by the S-Force's arch-nemesis, Ender, as he too believes Coop is evil.

Coop accidentally damages a vital part of Megas, the photonic stabilizer. Without it, Megas will go up in a blaze of fiery glory and explode, which will not only destroy Megas, but also, everything within a 100-mile radius. Fortunately, Coop found a junk planet that probably has just about everything. Unfortunately, Varshin the Dealer wants Megas' time drive to complete his own robot and sends various "zombie" robots to retrieve it. Even more unfortunate, Goat has come along for the ride, and is thoroughly annoying Kiva, not to mention he's fantasizing about a personal robot of his own without any idea how to get or build one properly.

Coop accidentally teleports himself directly into the Karrajor, the Glorft Mothership, and now Kiva and Jamie have to figure out how to pilot Megas to save him. They do okay at first, but eventually crash into the Glorft mothership and get themselves - and Megas - captured. Fortunately, Gorrath foolishly lets Coop get the car, so Coop tears through the ship, intent on rescuing his friends and Megas. Now Coop must rescue everyone while finishing off the Glorft invasion once and for all, but how is he supposed to do that when the sheer amount of Glorft mech's overpowers even Megas and tears off several vital parts? Even worse, the Glorft have a new mech, the Karrajor in Mech mode, which is even larger than the UMD, which raises the question: how will Coop defeat this new threat with a critically damaged Megas?

Coop accidentally destroys a sacred treasure of the Azion Worlds, a robotic, alien empire - the Flame of Azeroth. The Emperor declares whoever captures Megas and bring it to judgement will be named as the new Emperor, so now Coop has to fight off a bunch of Azionites in the deep, dark reaches of the final frontier, all of which are, if necessary, willing to destroy each other to become the Emperor. (Note: due to a tape mixup, this episode was not shown until nearly a year later).

A floating alien head invites Coop to participate in a tournament; Coop is asked to take a dive during one of his fights for a windfall.

After buying a game cartridge from a garage sale, Coop accidentally releases dangerous prisoners from an inter-dimensional prison.

In an attempt to fix the television, Coop accidentally causes a blast of concentrated television waves to go out into space and attracts a giant, radio-wave eating monster to Earth. Due to the fact it is eating all the TV-satellites, it is impossible for anyone to watch any TV. Coop needs to stop this thing at all costs, but there's one major snag - how do you stop a planet-sized monster that eats television waves, not to mention that it has a bunch of killer boogers inside its body?
