Rosemary was born in 2000 and to the same parents as Britney. In the beginning of Ultima X, she was possessed by Jerome Jears and it took a long battle with Dalexis to free her. She then met Genesis and Jalen and became a Saiyan Shadow. She fought along the heroes against Jerome, Utonium, Eggman, Bowser and many other forces. Rosemary's character has got to be one of the least developted ones of the series, since her IRL counterpart is 100% based on this, the creator didn't have a hard time with her. Her mother's a Saiyan and her father's Puerto-Rican.
Rosemary's very naive and not all that bright at times. But other than that she's funny, nice and a bit hotheaded. Her grammar might be good, but her wordplay could use some work. Sometimes, she may grief over the fact that she had to leave everyone else behind, but she's always eager to try new things. It may be noted in her character that Rosemary can get off topic sometimes and become childish, but that's just her.
Rosemary can move and fly at hypersonic speeds, like her family. She can also use the special energy dubbed "Ki" and manipulate it better than expected.
Galick Gun- Something she was taught by Vegeta during her year-long special training. She gathers a large amount of ki in her hands and fires it in a sort of gun formation as a purple beam.
Rose Pedal Volley- Rosemary can shoot multiple energy bullets at enemies, but only about five(the number of Pedals on a rose).
Rose Pedals- To be announced.
