Trent Fernandez-Mercer is a Reefside High School student and the White Dino Ranger of the Dino Rangers. Retroactively, he is also referred to as the Dino Thunder White Ranger or White Dino Thunder Ranger, though these are in reference to the show, as opposed to proper labels.

Initially, Trent served as the main antagonist of the three-parter White Thunder, and from then on as a recurring major antagonist until Mesogog's spell over him was broken.

Drago Power, White Ranger!
