Jordan Underhill was one of Summer's high school friends, he can transform into Kamen Rider Omega. Earlier, in the World of Phi, Ashton stumbled upon the Emperor's Belt, taking it in place of the Phi Gear. This was never mentioned again.

History
In the World of Dark Riders, where monsters have replaced humans and taken on their forms, Jordan's alternate self had been killed and replaced by this impostor, who can transform using the Emperor's Belt into Kamen Rider Omega. Omega was destroyed by Chrono Warrior's Complete Form by Chrono Warrior summoning Phi Blaster Form.

Kamen Rider Omega
The Omega Gear gives the wearer the following abilities when they transform. Kamen Rider Omega has a more ornate appearance than any of the previous Gears, the Rider form having robes made of Sol Foam for a majestic appearance. Omega appeared to have immense strength on par with Kamen Rider Chi, however it appears to be much slower than Phi. Unlike Psi, the Omega Gear's weapons are still visible while not transformed, although Omega's sword, the Omega Stlanzer, is not disguised as an everyday household item.
