Trent Moseley

Trent Moseley is an intense, emo guy who shares Maya Young's interest in conspiracy theories and alien visitations. Although he claims to hate everything, he likes Maya but hasn't revealed this to her. He works at Maya's aunt's bookstore with her, until he is accepted by the No-Men, after hacking into their system to save Kit and if he didn't, he would be arrested. He then helped the Kamen Riders under a bigger capacity.

History
When Xaviax's ghost appeared at the No-Men headquarters, Trent attempted to attack him only to end up as Xaviax's host. Under Xaviax's control, Trent attacked his fellow agents, among them Michelle Walsh, who soon informed this to Kit & Len after Trent/Xaviax left.

While in his body, Xaviax through Trent recruited Brian, a social outcast who also happens to be Len's Earth counterpart, & gave him the ability to become a Kamen Rider & his right-hand man.

During a fight against Dragon Knight & Wing Knight, Trent was vented, which resulted with Xaviax losing control over him. Before losing consciousness, Trent suddenly realized his friends under their armor.

After waking up, Trent started to feel outrageous guilt for recruiting an evil Kamen Rider & fighting his friends, all while under Xaviax's influence. Kit, Len, & Maya comforted him, explaining to him that it wasn't his fault. Although no longer under the influence of Xaviax, Trent was able to once again transform into a Kamen Rider. Eubulon gave Trent the Onyx advent deck which was previously to Adam temporary, while Ariel Meyer had the Motha advent deck. Just like Maya gaining the ability to fight by installing the memories of Kase through Eubulon, Trent was able to do the same thing. But Trent got the memories of Kit Taylor and Adam.
