Alieda is the crew leader of Stallion Riders in Tier 3 and its the third boss of CSR Racing. She and her crew control the city district known as the "East Bay." She had a close relationship with Yoshiro but they broke up. She now gives him the cold shoulder.
Alieda drives a blue BMW M3 coupe, a very powerful vehicle for Tier 3 with a 546 power rating. However, the entire crew will race in half-mile races exclusively, including Alieda in the high stakes challenge. Because of this, Alieda herself is fairly easy to beat with a high top speed vehicle, as the M3 does not perform well on the Half Mile. Vehicles such as the Audi RS 3 Sportback, Chevrolet Camaro ZL1, and the Mercedes-Benz C 63 AMG Coupe, in spite of their much lower power rating compared to Alieda, will win in the High Stakes challenge with incredible ease, not even needing a Mechanic's assistance.
After being beaten by the player, Alieda will call Carlito to warn him about the new racer coming his way. Carlito, being much wiser and more considerate of his opponents than other crew leaders, considers it, but still taunts Alieda in the process.
At the moment, she is the only female boss and the boss who didn't mention Nitro in her phone calls.
