Jupiter's Biography
She was born and raised in Jubilife City. She wanted to be a bitch when she grew up and she was wrong. Her father, Lambda was a Team Rocket executive. Holland (now known as Jupiter) was mean snotty and liked to cause trouble. When she was a teenager she wanted to be part of this new team called Team Galactic. Her father said no and wanted her to be a Elite Officer in Team Rocket. She said she will give it a try but she failed and got kicked out. She would have gotten the job, but she was a computer whiz and that's why Team Galactic hired her, but she got a job there for a computer software manager but she failed at that and every grunt there laughed but Saturn had grown to like her a lot. So he gave her a promotion and she fired everyone who laughed. So she went to control there building in Eterna City. So she became the boss of that building and that's why the player battles her in the same place.
