Cobra Commander tries to blame everything on his troops, but Golobulus tells him again that he failed. Cobra Commander then tries to blame it all on Serpentor, but Golobulus has had enough. Everyone goes outside, and wait next to some strange objects. Golobulus says that these are the ultimate fruit of hyper genetic manipulation, a weapon no enemy can withstand.

He explains that, in several hours, these things will mature and launch hundreds of giant pods into orbit. The pods will bear spores, and the spores will degenerate all organisms they touch, mutating them into primitive, incompetent lifeforms. Pythona then says that when the pods ripen they will burst, and shower the Earth with enough spores to reduce the entire human race to the level of mindless beasts.

Golobulus says that only those beneath Cobra-La's ice dome will be spared. But the pods will not ripen in freezing space without energy. Serpentor realizes this is why they must have the broadcast energy transmitter. Cobra Commander says they don't have it, and they don't even know where it is, so their plan is laughable. Golobulus says his punishment won't be. Cobra Commander asks about his trial, but Golobulus tells him it's over -and the verdict is guilty! Guilty of the one unforgivable crime: failure!

Nemesis Enforcer comes over, holding a pod full of spores. Nemesis Enforcer holds Cobra Commander's head before the pod, which opens up and covers him with spores. Cobra Command rips part of his jacket off, and his skin color changes to green.

Golobulus tells Nemesis Enforcer to throw Cobra Commander into the abyss of oblivion. But Serpentor suggests putting him in with the Joe prisoners, so they can see the fate that awaits them. Pythona likes the idea, calling it poetic in its simplicity. Golobulus calls it a trifle melodramatic, but tells Nemesis Enforcer to take Cobra Commander away.

Elsewhere, Lift-Ticket and Wild Bill are flying Falcon out to the Slaughterhouse via helicopter. Lift-Ticket throws Falcon a parachute, and Falcon wonders what they are doing here, as this is the middle of nowhere. Lift-Ticket tells him that's where he belongs, and then boots him out of the helicopter.

Falcon lands. just stopping himself from falling off a cliff. But as he gets up...

...someone else is there, and they have a Cobra symbol on their jacket! He tries to tackle him, but gets thrown to the floor. Falcon pulls out a gun, but it gets sliced apart by a sword before he can fire it.

Another man has appeared, but then another guy grabs Falcon and says look at what dropped in -170 pounds of air pollution! They start throwing Falcon around and insulting him.

Falcon throws one of them, and they are about to start fighting, but then someone tells them at ease. Sgt. Slaughter appears.

Slaughter says he's been expecting Falcon, and introduces himself as the special drill instructor for G.I. Joe. Falcon tries to excuse himself, but Slaughter tells him he's going nowhere. His job is to whip him into shape, and he's talking whip! There's only two ways out of his command, one is on your feet like a man, the other is in a ditty bag -an itty, bitty ditty bag! He tells him to meet the Renegades, who aren't real dependable yet, but once he's through with them... he asks them what they're going to be, and they all reply with one word: perfect!

Slaughter says that Mercer is an ex-Cobra Viper, who has seen the light. Red Dog, who was booted out of pro football for unnecessary roughness. Finally there's Taurus, a circus acrobat with a few loose bats in his big top.

As Slaughter and the Renegades get on their vehicles, and Slaughter says that now they're all close friends, they can head to the Slaughterhouse. He tells Falcon to grab his gear and start hotfooting it, if he wants to be there in time for breakfast. Falcon asks if they expect him to walk, but Slaughter tells him he can run. They move out, whilst Falcon runs after them.

Back at Cobra-La, Cobra Commander is taken to where the captured Joes are. The Joes wonder what has happened to Cobra Commander, but Roadblock tells them to forget that, and remember the plan. When the guards open the gates, they're gone! The guards unlock the gate, and the Joes rush them.

As the Joes run off, Cobra Commander has been left behind, and tells them to wait for him. Meanwhile, Serpentor tells Golobulus that the world will soon be theirs, but Golobulus just tells him may his deeds match his words. They then hear some shouting and see the Joes. Serpentor says they must destroy them, but Golobulus tells him he'll find Cobra-La is prepared to handle all contingencies.

The Joes head towards the exit, but as Roadblock is about to follow, Cobra Commander tells him to stop -it's a trap! He tells Roadblock to look. The Joes continue on towards some trees.

But as they run, the trees come to life, wrapping vines around the Joes and pinning them to the trees. Cobra Commander tells Roadblock that there's nothing he can do to save them, but he knows another way out. He tells Roadblock that he can save himself, and fight again. Roadblock asks him what is his fee, as snakes don't give for free. Cobra Commander asks him to take him along.

As some royal guards run past, Roadblock tells him that they have a bargain. The two move out, but are seen by Golobulus. He tells Nemesis Enforcer to dispose of them.

Nemesis Enforcer flies over and lands in front of them, and releases some spores. Some of them cause Roadblock to go blind, but he is able to elbow Nemesis Enforcer in the back.

Cobra Commander tells Roadblock that he'll be his eyes, and tells him which way to run. But his bad directions cause Roadblock to run straight off a cliff, and the two fall into a river below.

Later on, the spore pods begin to launch into space. Baroness says that they're beautiful, and Destro says this begins the dawn of their invincibility. Serpentor orders everyone forward, as their mission is not complete until they return with the broadcast energy transmitter.

Meanwhile, Roadblock and Cobra Commander have survived, but Cobra Commander seems to be losing his mind, saying that everything is useless, and how he was once a man. His mask falls off, which Roadblock picks up. Cobra Commander says that was his mask, just as he was once a man. Roadblock wonders what the sound is, having heard the spore pods blasting off. Cobra Commander says it's the beginning of the end of human civilization, unless he warns G.I. Joe in time.

As the Slaughterhouse, Falcon finally arrives, but Slaughter tells him that he's missed breakfast -that's what he gets for being so out of shape. He thinks maybe a little KP will get the led out. Later on, Falcon starts training like he's never trained before...

...with a little help from the Renegades. Duke contacts Slaughter, and Slaughter can't believe Flint hasn't found a trace of Roadblock's unit. Duke says the Himalayas are a big chunk of geography, but they can't wait any longer. He wants Slaughter to infiltrate the Terror Drome, and find out if Cobra knows what happened to Roadblock's men. He then asks how Falcon is doing, Falcon is currently sparring with the Renegades, and Slaughter tells Duke it's too soon to be sure, but he thinks Falcon has potential.

Slaughter then rounds up everyone, and tells them that they're going to infiltrate the Terror Drome on Cobra Island. Mercer thinks that's suicide, but Slaughter says to think of it as an extra rough training exercise. Falcon thinks in that case they should leave their weapons behind to make it really educational. Slaughter says that's what he calls a challenge, and says no weapons, something which the Renegades aren't happy to hear.

Meanwhile, the B.E.T. has been moved to a place where the Joes think Cobra will never think to search for it: a civilian security lab. However, a disguised Baroness runs out of the lab, having heard and seen everything.

The Renegades arrive at Cobra Island. After covering up their Devilfish vehicles, they run over to the side of the Terror Drome. Slaughter asks Mercer how they get in, and Mercer says that in this stinking swamp, even big bad cobras need air conditioning. He points to a vent, and says it's their ticket in. The group head up the side of the Terror Drome.

They manage to get in, and come across Serpentor giving a speech. He says that the Baroness has located the broadcast energy transmitter, and the Joes can't stop them from capturing it now. He tells some pilots that once the battle is over, they will have the honor of flying the transmitter back to Cobra-La. Red Dog asks what Cobra-La is, but Mercer says he's never heard of it. Taurus says that answer gives him no comfort.

Slaughter tells them that right now, they've got to warn headquarters. He tells Falcon to get the word out, whilst they blow up the armory. Slaughter's group arrive at the armory, and quickly take down some guards. As they grab some weapons, Slaughter plants a bomb, which is set to explode in 15 minutes.

They then get into a firefight with some enemy troops. Falcon gets to the communications room, and tries to contact G.I. Joe. Slaughter thinks that if the enemy keeps shooting, they'll all blow up. He picks up an empty missile rack...

...and drops it on the enemy troops, forcing them to flee. Elsewhere, Tomax and Xamot, along with some other Cobras, enter the communications room. Falcon starts fighting them.

Slaughter's group exit the Terror Drome, but Slaughter asks where Falcon is. Red Dog says who cares, as they don't need him. Slaughter tells him it's time he learned they're a team, and either they all go home, or nobody goes home! They fight their way back into the Terror Drome.

Falcon has been taken to Serpentor, who wants to know how many men are in his force, and what the purpose of his mission is. He warns him that he can't resist forever, and Falcon tells him he's right -but all he has to do is hold out for 5 more minutes. Serpentor tells him that if he won't answer him, he can answer Nemesis Enforcer.

Slaughter's group then run into the room, and start firing. Nemesis Enforcer throws Falcon away, as Slaughter runs up to him. But Nemesis Enforcer throws a creature at Slaughter, which attaches to his face.

Nemesis Enforcer hits Slaughter several times, and Serpentor tells him to finish him off. The Renegades start firing at Serpentor, and he tells Nemesis Enforcer to help him.

Nemesis Enforcer flies over to where Serpentor is, and uses his wings to protect him. Falcon gets the creature off Slaughter's face, and seems surprised they came back for him. Slaughter tells him not to get sloppy, but then wants to fight with that overgrown bat. Taurus says there's no time for a rematch, the bomb is about to go off!

The bomb explodes, destroying the Terror Drome. The Renegades get back to their vehicles, and retreat. Taurus thinks Cobra is finished, but Slaughter tells him not to bet his beard on it.

A structure ascends from the wreckage of the Terror Drome, and the surviving forces of Cobra appear. Serpentor says he wants their heads, this he commands! Cobra launches a full assault.

They arrive at the lab, and begin their attack. The B.E.T. is placed in a metal shield. Duke thinks Cobra must be after the broadcast energy transmitter, so Hawk tells him to rally the ground troops, whilst he calls out the airborne assault team.

As the Joes head off to battle, the Rawhides head out. They want to fight too, but everybody has moved out. Jinx spots a helicopter they can use, and they all board it. But when Jinx tries to start it up, the rotors sputter out.

The Joes begin their counterattack, but forces of Cobra-La appear. Their weaponry creates tentacles which restrict the movement of the Joe's vehicles. Duke tells everyone to shoot down whatever those things are.

The Rawhides get the helicopter working, by having Chuckles manually start up the rotor blades by giving them a push. They head out to battle, but after a few seconds the helicopter gets hit by some tentacles, which jam up the rotors.

The helicopter crashes into a building, and whilst everyone survives, Law can't believe that they were shot down be salad. Hawk tells everyone to pour it on, as they can't let them get their hands on the B.E.T., but he has to retreat when a new group of enemy planes fly in.

Serpentor leads them. He says to maintain their air attack, and deploy the marauders! A massive, snake-like creature bursts out of the ground.
