Sweeps
From Multiversal Omnipedia
When Unicron created the dreaded Scourge, he created an armada of huntsmen along with him called the Sweeps. The Sweeps, created from fallen Decepticons (Destrons), possessed their own independent intelligence. Galvatron often made use of the Sweeps in battle.
Comments
Despite the limited number of Sweeps created by Unicron, there seemed to be a nearly endless amount in the Decepticon army. Since some of the Sweeps were created from fallen Insecticon clones, it has been suggested they retained the ability to duplicate themselves.
