The Centurions

As the Strafers approach the falling space station, Crystal and John risk turning the computer's power back on to destroy them. In order to free Skyvault's computer from Terror's control, Ace uses the Orbital Interceptor to travel up to Skyvault with Dr. Wu's anti-viralizer ray, avoiding the station's self-defenses after being beamed aboard. Meanwhile, at Gog's island cybernetic hive, Terror has taken the World Council of Scientists prisoner, and shows them Gog's new Triad weapon to fight against the Centurions.

Thunder, now a prisoner of Gog and Terror, is rescued by Crystal when she is able to successfully escape and elude Hacker. The two however remain powerless to help the remaining Centurions on the planet fighting to take back New York from Terror's armies. Terror makes a stern demand to the members of the science council that rejected him years ago.

Doc Terror reflects on his past as his partner Hacker while he stows away on board Skyvault and seizes control of the station. Terror boards and begins coordinating his campaign of destruction, ordering Magog to begin full distribution of a vast, unending armada. John Thunder attempts to find a way of saving Crystal and everyone trapped on the station.

New Centurions are recruited by the team and trained in the Centurion Academy, whilst Sealab develops new weapon systems for the original three. Meanwhile, Doc Terror makes contact with an alien computer called "Gog".

Doc Terror observes scientist Marina Abbot's ship heading out to sea and sends out sea-borgs to attack it. The Centurions are sent to defend the ship, while Marina summons help from a giant lobster. After the battle, Marina explains to Max that she has taken over her father's research, but wishes to keep it secret. The ship heads to the research base Neptune-1, and the Centurions observe the giant lobster and a giant turtle first hand. Marina tells them that the creatures are to be used by the World Council of Scientists and that each one can be controlled with an implant. She swears not to have her work destroyed by Doc Terror like her father's early research. Ace is later trapped by Marina, who tells him that she wants to lure Terror to the island and take revenge against him for her father. As Terror begins transforming the creatures into cyborgs, the Centurions arrive to defeat them. Science Lesson: Swan ships by Max.

Terror follows the wandering vortex, attempting to bring it back under his control, while John manages to escape from Claw. The other Centurions, still looking for Dominion, come under attack by their own weapon systems, which are transformed into creatures by the vortex's alteration of reality. Crystal beams them to Skyvault, leaving John still on his own in Terror's Arctic base. John finds a transmitter and contacts Skyvault, but the co-ordinates are unstable as the position of Dominion is not stable anymore due to the vortex. Crystal is able to beam the other Centurions to Dominion, where they meet up with John, who tells them that he still has to deal with his old enemy Claw.

John Thunder informs the Centurions that his old sparring partner Claw is now working for Doc Terror as a cyborg. Meanwhile, Doc Terror succeeds in creating a dimensional neutron vortex in his base, Dominion. Energy from the vortex is detected by Skyvault, where Crystal determines that the laws of reality will soon collapse. With Terror having stealth and scrambler fields all over the Arctic to hide his base, the Centurions lure Hacker into stealing a vital component for the vortex, and John sneaks on board Terror's airship. John makes it to Dominion, where Claw soon senses his presence and alerts Terror, who then gets Hacker to attack the SETI space probe station in the Andes to keep the rest of the Centurions occupied. Claw captures John and attempts to settle old scores with him. The other Centurions are sent to locate Dominion, but are too late, as Terror's dimensional vortex breaks out of control.

In Dominion, Doc Terror attempts to turn his dog Brutus into a cyborg, but there is a malfunction that halts the mechanisation process while still giving the dog cyborg strength. With this knowledge, Terror creates the Encephalocaster, a device that can control other animals as well as giving them cyborg-enhanced strength. He uses the device on Skyvault and gains control of the space station with the help of Lucy. Once there, he uses the device to control all animals on Earth. As Jake attempts to deal with a Terror-controlled Shadow, Terror and Hacker prevent the other Centurions from beaming to Skyvault. With the Earth under siege by Terror's super-strong animals, the Centurions must figure out a way of getting to Skyvault and evicting Terror as well as shutting his Encephalocaster down.

However, the meteor has already been launched toward the San Andreas fault line, and only Ace alone can stop it. Science Lesson: The Moon by Crystal.

A meteorite with alien life on its surface falls into the Arctic Ocean. Doc Terror wants it, and sends Mako to retrieve it. Sealab is also interested in the meteorite, and comes into conflict with Terror's forces. The Centurions are sent to diffuse the situation. However, problems later arise when the new Mark-1 A.I. Prototype onboard is infected by an alien virus carried by the meteorite. With every electronic system on board Sealab affected, the Centurions have to neutralise the virus before Doc Terror's approaching forces arrive. Science Lesson: Arctic Ocean by Max.

A shower of meteors heads towards the Earth. The Centurions are sent to try and stop them, however, one of them crashes into the desert. Doc Terror scans it and discovers an invulnerable plant growing on its surface. He gets Amber to place a seed from the plant onto Jake's dog, Shadow so that the Centurions' secret base is attacked by the plant. The plants quickly multiply and proceed to attack the rest of New York. The Centurions discover the existence of a master plant-borg that controls all the others, and try to destroy it.

An asteroid containing a powerful ore known as Superium is being transported to Earth. The ship carrying it is attacked by Doc Terror. The Centurions save both the ship and the asteroid, but problems arise, when the Executioner, a master criminal who thinks he lives in the past, takes the place of Dr. Emerson on Earth. Emerson was to have given Crystal a special circuit to enable the safe beam-down of the asteroid to a secret location, but the Executioner instead substitutes it with a chip that takes control of Skyvault's computer. The asteroid is then guided to the Executioner's castle, ready for Doc Terror. With Jake trapped on board Skyvault, Ace and Max captured, the Centurions must find a way to stop both Skyvault's computer and the Executioner. Science Lesson: Asteroids by Ace.
