Sorbet was a staff officer of the division. After Frieza's death, Sorbet took command of his Frieza Force remnant, with members including Tagoma and Shisami. Some time before they revived Frieza they made use of improved Battle Armor.
The Third Stellar Region was absorbed into the New Frieza Army deployed during Frieza's revenge against the Saiyans. They, along with the rest of the army, were defeated by the Dragon Team and killed by Frieza.
