Here is the page on Jessie, her profile is below:

Name: Jessie/Musashi

Japanese translation:

Age: 22?

Portrait: Long red hair; gray eyes; Team Rocket uniform (duh!)

Pokemon owned: Wobbuffet, Dustox, Seviper

Pokemon she used to own: Arbok, Lickitung

Synopsis of her life: Her mom, a high ranking Team Rocket member, was sent to look for Mew but was buried in an avalanche. Then Jessie enrolled in a school for Chanseys to learn to be nurses. (The details in my mind get foggy here.) Then Jessie joined a bike gang from Sunny Town (cool name - not). She was called "Big Jess" in the show because she always swung a chain around when she rode. Well then, she joined up with Team Rocket.
