The White Dino Ranger Clone is a negative copy of the White Dino Ranger energy created by Mesogog and Zeltrax. This souless and evil Ranger has absolutely NO trace of Trent Fernandez-Mercer inside him. He isn't considered a living being at all.
Despite being evil, he is honorable and complements his opponents skills more than once.
He was destroyed by the real white ranger Trent Mercer.
Years later he was bought back to life by the being called Phantom Fienox. Using his powers and his Drago/StegaZord The Clone servers as a soldier in Phantom Fienox's army.
