She works for Space Channel 5 in a segment called "Ulala's Swingin' Report Show!" She spends most of her time battling aliens by dancing, and rhythmically shooting.
In 2003 pop star Miss Lady Kier filed a lawsuit against Sega, claiming the company based Ulala's character and styling on her own. She said Sega had approached her before the game's release asking permission to use her song "Groove is in the Heart" to promote the game, an offer which she declined. During the 3-year battle, Sega came up with sufficient evidence to prove not only that the character was not based on her likeness, but that they hadn't even heard of her at the time the game was released. She lost the case and was forced to pay Sega's legal fees.
