The Gross Sisters, Nubia (voiced by Raquel Lee), Gina, and Olei Gross are the main antagonists in Disney Channel's The Proud Family.
They are bullies that go out in public demanding people for their cash. They are three girls constantly mugging people for money and show violent tendencies (bullying). Their parents make them work on the weekends. Their mother is Jamaican; she wears orange flower print clothes and her hair in dreadlocks with a barrette. The remainder of family is entirely blue including their clothes (except the sisters who wear black overalls). The reason why is because their family can't afford lotion and they work in the hot sun all day.
Nubia is the middle child and the leader of the pack, considering she is the only one who talks. Gina is the oldest, despite being the smallest. She collects money from her sisters' muggings; as a habit, she always has her hand out. Olei is the youngest and the biggest of the 3 sisters. Like Gina, Olei is silent most of the time. In the episode, "Makeover," Olei (who is known as the "muscle of the group") is separated from her sisters.
Although they rarely get in trouble for their deeds, in one episode they are actually caught. They are usually friends with, but sometimes they bully her and her friends. After witnessing Penny fighting the Carver clone on national TV, they develop respect for her with Nubia calling Penny "hardcore." Their catchphrase is, "Hands up. Cash out."
- The Gross Sisters are bullies similar to The Ashleys from Recess. The only difference is The Gross Sisters aren't as annoying as The Ashleys.
