Turt

Turt is a Torterra that was the 1st Pokémon that Jaiden uses on her Pokémon Platinum Nuzlocke. He survived the entire nuzlocke.

History
Turt was chosen as Jaiden's starter, defeating Barry's Chimchar in battle. Whem arriving at Route 202, Turt KO'd Jaiden's encounter Shinx and nearly was killed by Youngster Tristan's Starly. After soloing Barry's team in Route 203, Turt was used again in the Oreburgh Gym, defeating the Gym on his own.

While battling Team Galactic Grunts in the Valley Windworks, Turt evolved into a Grotle and defeated Mars' Purugly. He later defeated Jupiter's Skuntank, but was nearly killed in the process. In Wayward Cave, Turt KO'd a Gible Jaiden meant to catch. Though not seen in the animated video, Turt evolved into a Torterra after defeating a wild Rhyhorn.

Turt was used to help defeat Byron, as well as later defeating Mars' Purugly again. In Team Galactic's HQ, he defeated a Porygon2 that had killed Squoop.

Turt was one of the Pokémon brought into the Elite Four. He was used to help defeat Bertha. During the Cynthia battle, he defeated Cynthia's Spiritomb. He was one of the 3 Pokémon still alive at the end of the nuzlocke, along with See and Flakes.

In the alternate timeline, Turt was also used to help defeat Bertha, but contributed more due to Oops and Flakes dying. It is presumed that he would have died during the Flint battle.
