With the Destrons starting their energy plundering scheme, Galvatron already has his first target in mind: planet Beehive, or just Hive for short. As they close in on Hive, Soundblaster picks up a blip on their radar. They see that a Hive spaceship is heading in their direction.
On the Hive ship, the Captain has seen MegaZarak, and knows that it must be a bad thing as it has the Destron insignia on it. MegaZarak opens fire on them, and they flee. The Captain sends a signal back to Hive stating they need assistance, but then their ship is hit and badly damaged. Galvatron says to ignore it and continue towards Hive.
Meanwhile the Cybertrons are chasing after the Destrons, and eventually find the wreckage of the destroyed ship. Chromedome flies over to investigate it, but only a small part of the ship remains intact, and even that has a large hole in the side of it. Inside the ship Chromedome finds nothing but more wreckage and dead bodies, but a single survivor appears and mistakes him for a Destron. Chromedome says he's a Cybertron and takes the survivor back to Battleship Maximus.
The survivor is given some medical treatment and the Cybertrons ask him if he was attacked by the Destrons. He says he was and then goes on to explain about the planet he comes from. Hive is a large world where the workers collect energy from space and store it within the planet. The planet is ruled by the Queen Bee, who lives in a tower surrounded by an energy moat.
Meanwhile inside the tower the Queen Bee is told that a Destron ship is heading straight toward Hive. Knowing that the Destrons are coming to take their energy, the Queen Bee tells her defense commander to recall all ships and then send the fleet out to intercept the Destrons, before they can come close to the planet.
Back on Battleship Maximus, the Cybertrons discuss what the Destrons are going to do when Daniel runs in and says that the survivor is calling for Chromedome. Chromedome heads back to the medical room and finds that the survivor is going to die soon. The survivor gives Chromedome a medallion and tells him to find and give it to his son, Makku. A few seconds later, he passes away due to his injuries.
The Destrons finally have Hive in their sights and head towards it at full speed. Galvatron decides to lead the invasion personally and takes Sixshot and the Horrortrons with him, leaving the Destron Headmasters in the cold. They complain that Galvatron underrates them, but MegaZarak says they need to wait -the time for them to show their true power will soon come. For now, they'll just follow Galvatron's orders.
With Galvatron and the other Destrons making it into the planet, the Hive army starts to attack. But are no match for the Destrons, who start to shoot all of the attacking ships down. The Queen Bee orders for all children to be evacuated immediately. Most of them get away, but one stays outside due to a Hive spaceship crashing right next to him.
Meanwhile in space the Hive fleet has finally assembled and goes off to attack their enemies...but they end up shooting at the Cybertrons, apparently not knowing that they are the good guys. Fortress knows that they cannot counterattack as this would prove to the Hive fleet that they really are evil, so instead Chromedome, Hardhead and Brainstorm leave their ship and try to tell the Hive fleet to stop firing as they are not their enemies. but the Hive admiral doesn't believe them. This is reported to the Queen Bee and the defense commander tells her that the Cybertrons are Transformers like the Destrons, and are just here to steal their energy.
The Cybertrons return to their ship, having been unsuccessful in stopping the Hive fleet from attacking them. Fortress says that they must not counterattack, but this angers Chromedome as it means the Decepticons are going to steal all of Beehive's energy. He decides he cannot go with Fortress' strategy and flies to Hive himself. He sees that the Destrons have now made their way to the Queen Bee's tower. He transforms and heads there himself.
On the way Chromedome finds the child who did not get to evacuate with the others. Chromedome asks him if he knows a kid named Makku and it turns out that this child is Makku. Chromedome gives him the medal and tells Makku that his father died in battle against the Destrons. After briefly mourning his father, Makku shows Chromedome a secret entrance into the Queen Bee's tower.
Chromedome explains that he is an Cybertron and he is here to defeat the Destrons. The Queen Bee contacts the Hive fleet and orders for them to break off their attack on the Cybertron ship. Meanwhile outside, Galvatron and the other Destrons have destroyed the Hive defense force and make their way to the tower. Galvatron tells the Queen Bee that he wants all of their energy now. She refuses to hand it over, as her people were the ones who worked hard to get it.
Galvatron decides they can just take her and her people as slaves, and has the Destrons fire at the tower. Chromedome appears and starts to attack the Destrons, so Galvatron has the Horrortrons fight him. Galvatron then tells MegaZarak to enter Hive and launch an attack.
Apeface and Snapdragon struggle to take down Chromedome, so Galvatron and Sixshot transform and blast the Cybertron out of the sky. He lands in the energy moat below. The Hive fleet has stopped firing on Battleship Maximus, as the Queen Bee contacts the other Cybertrons, begging them for help and explaining what happened to Chromedome. Fortress has his ship move in at full speed.
Meanwhile, MegaZarak is smashing and shooting at the tower, when the other Cybertrons arrive. The Cybertron Headmasters head out to fight the Destrons, whilst Fortress stays in his ship and starts shooting at MegaZarak.
MegaZarak transforms to robot mode and flies over to Battleship Maximus. Meanwhile, Makku has entered the energy moat and helps Chromedome re-energize himself. He leaps out of the moat, as he helps the other Cybertron Headmasters push back the Destrons. Up above, MegaZarak has started bashing Battleship Maximus...
...but he doesn't see that the Cybertron Headmasters have arrive until it is too late. They pull off one of the ship's guns and fire it, using a technique called the "Master Shot". This shot hits MegaZarak and pushes him way back. Fortress sees this as his big chance, as he pulls out the Master Sword and transforms into Fortress Maximus.
MegaZarak charges over and starts punching Fortress Maximus repeatedly, but he is stopped when Chromedome and the others use the Master Shot again.
This gives Fortress Maximus the opportunity to strike deep into his opponent's chest with the Master Sword. MegaZarak pulls out, and the other Destrons follow him. Fortress Maximus heads out, as the narrator explains that by joining forces, the Cybertrons and inhabitants of Hive have defeated the Destrons.
