Adjutant

Adjutants are hostile Husk-like creatures that are introduced in Mass Effect: Invasion.

Mass Effect: Invasion
Adjutants first appear at the beginning of Mass Effect: Invasion. A Cerberus transport ship returning from a trip to one of the organization's research bases beyond the Omega 4 Relay docks with Omega and releases dozens of Adjutants onto the station. The creatures proceed to attack everything in sight, and advance to the doorstep of the Afterlife Club, the seat of Aria T'Loak's rule over Omega.
