Jenna Sheinfeld

Jenna Sheinfeld is Drew Sheinfeld's older sister. Years ago, their father had saved the world by isolating his entire research building into Hyper Space to contain the virus "Automon".

This time, it's her 18-year old brother who is trying to save the world, fighting against the Automon Foundation as the Red GB Ranger of the GB Rangers. This is not something she supports.

Later in the season, Jenna, feeling she must protect Drew, becomes a cat burglar using the alias, the "Pink GB Ranger". She steals the Automon Card 10 from an arts collector when Drew, Bradley, & Amy try to obtain it from him. She evades the three of them & runs into Hackers. They attack while Bradley & Amy deal with the foot soldiers while Drew continues to go after the thief. Drew loses sight of her & he sees Jenna walking down the street. It is at that moment that Drew discovers that it's his sister out of her Pink GB Ranger disguise as she gets in the back of her car. As she inspects the card with her magnifying glass, the card infects the magnifying glass & becomes the Loupetron.

When Drew catches up to her again & tries to take the Automon Card from her, he strips off her sunglasses revealing her face & realizes that was her earlier out of disguise. Jenna takes Drew's GB Morpher & asks him to quit the GB Rangers & come back home. Bradley begins to decline & she asks him to play the part as she tries to lure out the Loupetron who has been infecting people by absorbing their greed. She says she will stop stealing once the Viratron has been defeated & shows him a fake copy of the Automon Card. She tells Drew about the card infecting her magnifying glass & then rips the fake card into pieces.

The Loupetron & Hackers appears before them. Jenna returns the GB Morpher to Drew so he can morph into the Red GB Ranger. Jenna herself dons her Pink GB Ranger disguise & helps Drew fight off the soldiers. She leaves after Drew destroys the Loupetron with the Leo Cannon. The LoupeZord is then destroyed by the Gold & Silver GB Rangers in the Sector Megazord.

As the team returns to the Global Beneficiation Corporation, Jenna apologizes to Drew for being overprotective & promises to visit him everyday.

Pink GB Ranger
As the Pink GB Ranger, Jenna wore an outfit similar to the uniforms of the main three GB Rangers, with fingerless pink gloves. To hide her identity, she donned sunglasses like the GB Rangers, along with a pink wig.
