Trent Fernandez-Mercer

Trent Fernandez-Mercer is the Dino Thunder White Ranger.

Early Life
Trent is the adopted son of the multi-millionaire paleontologist, scientist and doctor Anton Mercer. His biological parents were archeologists and were killed in a cave-in as they were working on a dig with Anton Mercer several years before Trent moved to Reefside. After that, Anton took him in and gave him a life. He now considers Mercer his father, but kept his original surname, although he sometimes uses the name Trent Mercer. According to Mercer himself, when his parents disappeared, they agreed that he would act as Trent's father.

Dino Thunder Power Rangers
Trent works at Hayley's Cyberspace Cafe as the busboy/waiter and draws in his spare time, though he keeps this secret because his father "is in no way supportive of his artistic endeavors." as he disapproves of both, trying to encourage Trent to move on to activities more suitable for a Mercer.

After uncovering an invisiportal in his father's office, Trent was transported into the lair of the evil Mesogog, where he came in contact with the White Dino Gem, which transformed him into the White Ranger.

However, the Gem had a mind of its own, due to Mesogog and Elsa's reconstruction of its powers, transforming Trent deliberately whenever it wants.

The White Ranger had the ability to Camouflage, Super Speed, and Super Dino Mode. Besides this, he is rarely seen using any of his abilities. White Ranger has control over the Dragozord and later over the Stegozord, who can combine with the first to form the Dragozord Megazord. His weapons are the Drago Morpher, White Drago Sword, and Dino ATV. He briefly controlled the Cephalozord and the Dimetrozord.

The White Ranger worked as a loner, doing whatever he wanted with no one's help, until he partnered with Mesogog's team. When he was suspected of being a traitor and was about to be eliminated by the Life Extractor. During the draining process Mesogog turned back into Dr. Anton Mercer, and moved the drain device causing the energy to reflect off of things in the lab and land back into the Morpher with an explosion causing the evil in the Dino Gem to be destroyed and leaving the White Ranger power still active. Trent helped the other Dino Rangers, even with them don't trust him at first, per his father's request. He became the fourth Dino Ranger to unlock the Super Dino Mode during a fight with the Copyotter. He proved his trueness as Zeltrax was about to kill Tommy, Trent stepped in and saved his life. After this the other Rangers decided to trust Trent.

Trent then worked with the other Rangers, having to battle his evil clone, that Zeltrax created along with a other monster, the White Terrorsaurus. The clone was later destroyed in a battle with the White Ranger.

Early on, Trent and the other Dino Rangers team up with the SPD Rangers to battle the united forces of Zeltrax and Emperor Grumm. He teamed up with the Omega Ranger, but following their victory had his memory of the battle erased.

Trent kept his father's secret, even from the other Dino Rangers, which eventually led to them mistrusting him again when they found out. He gained their trust back after telling them why he kept it from him and after he saved Conner from a monster.

Trent spied on Mesogog, to learn that he had split himself from Dr. Mercer. With the revelation of this, the Rangers sped up their plans to destroy Mesogog's lab. Trent had made a deal with Mesogog that if he gave him the Dino Gems, then he would release his father. He told the other Rangers that if he gave him the Gems, he could open up an invisi-portal for them so that they could destroy his lab. The plan worked out exactly as planned and Trent saved his father.

Trent had later lost his powers as the White Ranger due to the final battle with Mesogog. Later, Trent is revealed to be going to art school in the fall, and his father is perfectly happy with it.

Power Rangers Ultimate Alliance
Trent was later called upon to the Abyss of Evil to stop the villains from drilling into the surface. His powers were restored and he could once again change into the White Dino Thunder Ranger. Due to his DNA altering in the terraportal, he reverted to the age he was when he first got his powers. During this time, he was possessed by his evil self, but freed when Ethan struck his Morpher.
