Well with Odin aka Wrath, there was possession with different users which then the power of Odin took control of the user's body, same with Xaviax as he took possession of the earth rider's body aka Vic Fraiser which then was concluded that Xaviax can also be Kamen Rider Wrath while only possessing any rider's body as his own. which case Possession is part of the rider

With Xaviax Imitating as a human or rider, like as with the Advent Master to only trick Adam who is the former Ventaran Kamen Rider Dragon Knight, Imitation is also another big part of any rider, like with Mitsuzane Kureshima from Gaim who also became Kamen Rider Zangetsu Shin temporarily to let the other riders believe that he was his bother Takatora Kureshima which then it was Imitation

You See Possession and Imitation are two different things of the Kamen Rider Series, and with them being on any series, they count for part of the rider's type, excluding Mitsuzane, he became a villain for a purpose and specific reason
