Nathan Taylor

Nathan Taylor is a hot-blooded boy who protects his high school from the Orphnoch with his reasons tied to his only friend in the school, Maria. As a student at Smart Brain High, Nathan makes himself look like he has little to no self-esteem with only Maria as his friend. Just like the original Phi, Nathan Yap, Nathan Taylor is also the Wolf Orphnoch.

Fictional character biography
Though he covered his secrets well, Nathan was forced to expose himself as Phi when the Lucky Clover members attack him and Maria. But it was after revealing himself as the Wolf Orphnoch to save her from the Tiger Orphnoch that Nathan loses his friendship to Yuri due to her prejudices against Orphnoch. Saddened and losing his reason to fight, Nathan attempts to dispose of the Phi Gear, only to learn the next day that Darren saved it while he was attacked by Ashton Seymour. When he learns the school is being attacked, Nathan fights the Lucky Clover on his own, exposing himself to the entire student body before being outmatched by the stronger opponents. But in spite of the odds, Nathan refused to let them destroy Maria's camera as Darren arrives to support him. But it was only when Ashton arrives with the Phi Gear that the tables are turned with the Tiger Orphnoch and his followers vaporized by the Phi Blaster. Soon after the fight, though now feared by the entire student body, Maria persuades Nathan to stay and protect the school again, rekindling their friendship.

While he does not appear to help in reviving Darren, but he still appears to help him battle Super Valkyrie, assuming Blaster Form with the help of Chrono Warrior's K-Touch and later uses the Jet Sliger to fight the Super Crisis Fortress.

Forms

Kamen Rider Chronology Warrior's Final Form Ride allows Phi to change into Faiz Blaster and use Chrono Warrior Photon to defeat the enemy.

Like all Rider gears, the Phi armor manifests when the Phi Driver generates Photon Blood, a glowing substance generates the soft Sol Foam suit, Sol Metal armor, and Fullmetal Lung chest armor via traveling through the red Photon Streams that ends at the Photon Terminals at the gauntlets and Power Anklet Greave greaves, the right Anklet having a Energy Holster that the Phi Pointer can be connected to. The helmet is unique due to its Global Feeler antenna to link up to Smart Brain's networks and Ultimate Finder visor that gives Phi incredible vision to see in darkness, giving the illusion of a glowing eye, and a limited amount of x-ray vision.
