However, before they can get into the building, Optimus Prime appears on the scene with the Autobot brothers! The Predacons fire off their lasers but the Autobots manage to avoid getting hurt. Clearly overmatched, the Predacons retreat.

Underneath the water is a Black Pyramid. Megatron has figured out that it is really a Matrix chamber that can amplify the power of Transformers. However, the chamber needs energy to activate, so Slapper and Gas Skunk begin draining power from the powerlines in the water to activate it. Meanwhile, Koji and Doctor Okase are on a ship to test out its new capability. Koji wonders how they can use it to explore underwater when it's not a submarine. Doctor Okase explains that the ship is capable of a maneuver that no other ship can accomplish, assuming no one else is in the water around the ship at the time. The Predacons are in the water however, and they fear this will draw the Autobots to them. Sky Byte and Dark Scream move out to destroy it. Meanwhile, Koji and the doctor prepare to use the ship's exploration capability. The entire ship suddenly changes to a vertical orientation, allowing the observation unit to move down into the water. Koji is eager to see the Black Pyramid. However, w

The other Spychangers are upset at Mirage. As the other Spychangers practice hand signals, Mirage berates them for practicing such mundane exercises. Meanwhile at Predacon base, Gas Skunk has created a tracking and listening device. They hope to use it to find the location of the Autobot base. At Koji's house, he is watching a news report on a ruby on display at a museum. The ruby is so large scientists believe that it can be used to create a powerful laser. Koji decides to tell Optimus about it, fearing the Predacons will try to steal it. He's right. At Predacon base, Megatron orders Sky Byte to steal the ruby so the Predacons can complete their super weapon: the Mega Laser. At Autobot base, Optimus tells Koji that the Spychangers are guarding the ruby. That night, their skills are put to

It is a location called Castle Peak, where a UFO was reported to have landed 60 years ago. Optimus Prime and the Autobot headquarters quickly head to the site. There, they find the Predacons already digging and Kelly on a nature walk. When Sky-Byte accidentally caves in the area, Kelly disappears while the UFO is revealed! Optimus scans the ship to find six protoforms inside the ship, still in stasis pods. The Predacons try to lay claim to the ship, but the Autobots argue otherwise. Suddenly, Megatron appears and steals the protoforms! The Autobots try to give chase but Sky-Byte, Dark Scream, Slapper and Gas Skunk hold off the Autobots while Megatron escapes. Later at the Predacon base, Megatron explains that

Megatron's plan to force mankind to surrender by blowing up their power-producing dams sinks like X-Brawn, Prowl and Sideburn, when his Decepticon Commando is thwarted by imposter Autobots.
