Jack Mighty

Jack Mighty is a young boy with telekinectic powers. He used to be part of a bomb disposal squad with his parents, and was taken in by Cartia who just wanted to use him for his powers. He was first ordered by Cartia to reprogram Linda to challenge Rio to a Gate Battle. After Rio won the battle Jack released his control of Linda and erased her memories of being reprogrammed and the gate battle.

Cartia then gave him the Jack Gate and ordered him to challenge Rio to a Gate Battle involving a game of Space Pinball, and offered him his freedom if he won. At the beginning of the battle Jack had the upper hand with his powers, but is overwhelmed when holographic sharks appeared and lost the battle. Carlos arrives late to watch the battle and accidentally knocks Linda's head off, this activated a more dangerous phase which put Mint in danger. Rio and Jack work together to save Mint and fix the malfunction.

Afterwards Jack becomes good friends with Mint and revealed what he knew of Cartia's intentions while they were on Sky Resort. After Rio lost her gates and Cartia took over Howard Resort, Jack and Mint worked together to help cheer Rio up and joined forces with Rio's friends to stop Cartia's plans.
