Season 3

It is the year 2020 where Noah Daniels is famous for discovering time travel, saving the world, and making the colonisation of space possible. Noah's comfortable existence is shattered when a gang of vengeful kids travel back to Earth through space and time from the colony on E-Delta — using the wormhole technology Noah invented — and kidnap his best friend Arushka.

Arushka is held captive on the planet E-Delta, where the Bioplex structure is the only thing that stands between the inhabitants and their hostile environment. You can't last long outside without an oxygen pack and during the time of the red giant sun, you can't last at all. Drako, the handsome leader of the E-Delta kids, advises Arushka to get used to her new home — she's sixty million light years from Earth and any hope of rescue. Noah and the Nomads have other ideas as Chip impulsively jumps through Noah's experimental wormhole. Noah pursues him and the two emerge on E-Delta and make their way inside the settlement after rescuing one of the young colonists.

Noah meets Curly, a grizzly old hologram who tells him why the E-Delta kids want revenge against Earth and their mortal enemy… Noah Daniels himself! He and Chip must break Arushka out of the Bioplex and get back to Earth before anyone discovers his identity. Meanwhile, on Earth, the animals in the Wildlife Reserve are under threat with Arushka away.

Drako and his gang make another raid on Earth, this time targeting the Horizon Foundation where Noah works. After forcing Noah's mother to give them access to the Foundation's encrypted computer files, they are surprised by Arushka while trying to escape with Noah. Arushka stops Drako from taking Noah back through a wormhole and in the confusion, a young member of the raiding party is left behind. Clio is alone and terrified by the strange beasts in the Wildlife Reserve.

After Drako's raid, Horizon Foundation security orders Noah be confined to his home for his own safety until the crisis is over. Chip finds Clio in the Wildlife Reserve and together with Arushka and Chip, begins to teach Clio about animals. In return, Clio shows them that not all E-Delta kids are bad. While confined to home, Noah searches the files Drako stole in an effort to determine what he came to Earth for. When Drako returns for Clio, Kwan and Arushka (along with Moshi), follow their new friend through the wormhole to E-Delta. Kwan is taken prisoner by Drako while Arushka flees into the hostile wasteland. Apra decrypts the files stolen from the Horizon Foundation, revealing the location of a very special asteroid in orbit around Earth. With a deadly wall of sand approaching, Arushka has no choice but to return to the Bioplex. Drako takes Arushka in but leaves Moshi out in the storm.

Chip helps Noah escape from his guarded home and the pair quickly discover their friends have been taken to E-Delta. Clio and Curly join forces to help Kwan and Arushka rescue Moshi. With the Bioplex's energy reserves running low, Drako decides to returns to Earth to deliver Noah an ultimatum: the safe return of his friends in exchange for a canister of Thunderstone. Drako double crosses Noah, taking the canister and destroying Earth's only wormhole transporter.

Apra commences construction of a robot drone which will deliver the E-Delta kids' revenge on Earth. Arushka is furious when Drako brings animals from the Wildlife Reserve through a huge wormhole — how will they survive on E-Delta? Meanwhile, Noah and Liz are "borrowing" equipment from their now off-limits lab in order to construct a makeshift wormhole transporter.

Mr. Greenway confesses to helping Drako steal the animals and gives Noah the final clue he needs to piece together what Drako has in store for Earth. Arushka and Kwan's plan for getting themselves and the animals back home goes horribly wrong when Drako decides to take Moshi out for a ride.

Moshi saves Drako from being trapped outside the Bioplex under the red giant sun. Ivan loses confidence in Drako's leadership and dishes out his own punishment to anyone who helped Arushka escape with the animals. Noah and Arushka prepare to return to E-Delta to rescue their friends and put a stop to Drako's evil plan. Kwan must continue to pretend he stayed behind on E-Delta on purpose. How long will it be before his true loyalty is discovered by Ivan?

While the young Nomads set up camp in a cave shelter, Noah and Arushka infiltrate the Bioplex. The key to Drako's strike on Earth is the Thunderstone canister. In the process of seizing it, Noah meets a hologrammatic version of himself at 45 years of age, who sheds some light on why the E-Delta colony went bad.

Noah and Drako are put in an uncomfortable situation when a wormhole opened by Liz brings them back to Earth alone. Ivan seizes the opportunity to assume leadership and take over the strike on Earth. Drako must reassess his opinion of Noah when he saves him from drowning. The two boys, once mortal enemies, strike a deal that will benefit E-Delta and save Earth from destruction.

Noah must find out what happened to the lost parents of the E-Delta kids to keep Earth from being put under attack by E-Delta. Little does he know that Ivan has imprisoned drako along with the other nomads. Ivan sends the robot drone, with the canister, through a wormhole to the thunderstone ring surrounding earth. noah and his family shelter from a hail of falling rocks, the first sign that the asteroid belt is spiralling in towards the planet Earth.

Noah discovers the secret to making E-Delta fertile, but first he must stop the Thunderstone Ring from crushing Earth. The strain of executing the strike on Earth has made E-Delta unstable and the kids are evacuated from the Bioplex in the hope that salvation will arrive before the red giant rises. Noah must bring the thunderstone ring through space-time in a crazy attempt to save two worlds and right past mistakes.
