Tyra is a character of the day who appeared in The Bridge Bike Gang (EP036). She is a member of a Biker gang who have claimed Cycling Road as their territory. They battle Trainers who are traveling across the bridge. She and Chopper, another member of the gang, are old friends of Jessie and James, as they were once part of the bike gang. Tyra battled Misty with her Cloyster. Tyra seemed to have the upper hand, but because of Team Rocket's disturbance, the battle was undecided. Tyra recognized Jessie as "Big Jess". She and the rest of the gang were ultimately scared away by the police; however, upon convincing Jessie, James, and Meowth to ride in the storm, she returned to the cycling road. There, she and the other members helped Ash deliver the medicine to the sick Shellder in Sunnytown. (Source: Bulbapedia)
