Though the team seemingly has long since disbanded, a select few of the former 'Team Rocket' still stand strong. Always hoping that one glorious return of the villainous pokemon trainers would happen.
Jennifer, however, is a case of this gone extreme. While they were still standing, she was hailed as one of the best, if not also the most insane, of Rocket Commanders.
Harsh and cruel are often used to describe her.
Behind her back, at least. The lass somehow still managing to compile a group of her own underlings, either out of fear or equal insanity.
Her pokemon of choice seem to cater mostly to Poison types. Granted, through her methods of obtaining pokemon as well, she's also collected an impressive range of beasts... though none compare, in her eyes at least, to her Vileplume.
In fact, it may be the only living creature the woman actually treats with respect constantly. So watch your tongue around it. She has her favorites, and she will make sure to please her favorites, should someone upset them.
