Giganta Yuss

Giganta Yuss is the secondary antagonist in Nerd. She is the widowed mother of Yi Yuss.

History
After escaping from the FBI in Japan and travels to New York, Giganta steals to pay for medical treatment for his daughter Yi, who has an unspecified illness. Giganta and his accomplice Rocky robbed the same wrestling venue that Charlie had competed as Giganta attempted to steal Grandpa's car to make his and Rocky's escape with the cash. Appacle Chief reasoned with Giganta, but Rocky's arrival shocked her and she shot Appacle at point blank accidentally. The police identified Rocky as the killer alone, but Giganta is eventually arrested and imprisoned for the attempted robbery of the Bank, which Giganta later swore revenge on New York.

Giganta is brought together with the prisones when they decide to follow along Rocky. Giganta helps all the prisoners to break out of the jail through the front due to her enormous size.

Rocky and the cellmates use the Monstrous Inmate to break into the Appacle Chief's Bank and it seems that Giganta was finally able to steal money to help her sick daughter. However, when Giganta finally grab it, it is a ruse and revealed that Yi is cured of her illiness, which Giganta is overjoyed. Grandpa tells Giganta that Fred already warned him about Rocky and his cellmates attempting to break in and hides all of the policemen in the safe. Giganta and Rocky, along with his cellmates, are then taken away back to jail.

In "Hit 'n' Run", Giganta and Rocky stole a military radio from Herman's Military Antiques (as he thought he'd get bodacious chicks with a military radio), but Fred managed to stop him. Giganta and Rocky was later arrested by Goodman when Sasha helped him uncover evidence of crimes under the three-strikes law (Counterfeit Designer Jeans, running over an elderly citizen without a permit, and littering, in that order) in exchange for information in regards to her missing boyfriend.
