What is the name of the Blue Ranger in Power Rangers: Dino Thunder?

The Blue Ranger in Power Rangers: Dino Thunder is Ethan James.

Ethan is one of three Reefside teenagers chosen to wield Dino Gems after encountering Dr. Tommy Oliver, who has become a paleontology professor. His Blue Dino Ranger powers are connected to the Tricerazord, giving him a defensive ability that creates an energy-formed shield over his skin.

Kevin Duhaney portrays Ethan, whose computer expertise distinguishes him from his teammates. Conner McKnight becomes the Red Dino Ranger, while singer Kira Ford becomes the Yellow Dino Ranger. Trent Fernandez-Mercer is the White Dino Ranger, making him another member of the same team but not the Blue Ranger.

Dino Thunder premiered in 2004 and brought Tommy Oliver back as the Black Dino Ranger, linking the season to earlier Power Rangers history. The team's dinosaur theme draws on the Japanese series Bakuryū Sentai Abaranger, as Dino Thunder adapts its footage and concepts for an English-language Power Rangers story.
