The Team heads to the South Pacific and soon finds a Kairu deposit in an ancient artifact called "The Fist of the Colossus".

When Maya is hit with an attack called "Lokar's Shadow", she finds herself drawn to the side of evil.

While hanging out on the X-Scaper, the gang detects a distress signal that Ky believes is from his missing father (it seems to be originating from a place they used to camp when Ky was a child). Against Baoddai's wishes, Ky sets out on his own, desperate to reconnect with his dad. But when he arrives at the remote, Alaskan location, he realizes the message was a trick, courtesy of Lokar -- and the Radikor E-Teens are waiting there for him. After a battle, Ky, and his father's X-Reader (which he discovered at the location and is full of X-Drives - including Gold Metanoid -- and diary entries from his dad), tumble into a steep gorge. Meanwhile, Maya and Boomer arrive in search of Ky and are surprised to feel the presence of kairu at the camp. They eventually find their missing teammate and defeat the Radikor. And Ky is brought one step closer to discovering his dad's true whereabouts. In a b-story, the gang tries to find a gift for Baoddai's birthday.

Ky, Maya and Boomer travel to Southern Mexico where they come face-to-face with the Kairu-absorbing force of the legendary Cataclysm Stone.

When the Imperiaz E-Teens use a mind-clouding attack to make it look like Ky broke a kairu code, he's promptly removed from Team Stax.

Mookee becomes a warrior-in-training and helps Team Stax battle the Battacor over a kairu-filled tree.
