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. Many years later, he returned in Power Rangers Super Ninja Steel along with other Legendary Rangers, helping the Ninja Steel Rangers against Lord Draven and his army of Robo Rangers.
