Appearances
s appear in the Fallout 3 DLC Broken Steel.

Locations
Known locations so far (that respawn):
 * The Capitol Building (Fast travel to The Capitol Building and there is a respawn of two Super Mutant Overlords on the stairs that lead up to the west entrance.)
 * Broadcast Tower KT8 north of Vault 87
 * Mason Dixon Salvage
 * On the roof of the Statesman Hotel.
 * South wall of the Citadel
 * Inside the National Archives
 * Hallowed Moors Cemetery
 * Roosevelt Academy
 * Clifftop Shacks (this can be a dangerous place to get drawn into a long fight, Deathclaws, Talon Company Mercs, and Enclave are known to randomly spawn very near.
 * West of Rivet City and East of the Jefferson Memorial
 * Three can be found in the L'Enfant District, each carrying one of the three weapons that Overlords are commonly seen using (Tri-Beam Laser Rifle, Super Sledge and Gatling Laser). Careful as there are ALOT of Super Mutants in this area along with destructable cars AND Enclave Troops will land at a intersection you may pass, so things can get pretty hectic. Stealth is advised.
 * Before you finish retrieving the GECK from Vault 87 in the begining of Murder Pass in Little Lamplight, if you have Broken Steel you will encounter a Super Mutant Overlord.
 * Inside the Corvega Factory. It is necessary to take it down for the master keycard in it's possession. (unless you have level 100 lock pick)
 * North across the river from the Anchorage War Memorial War Memorial in a tent along with Keller Family Transcript 5 of 5.
 * Near Wilhelm's Wharf
 * Museum of Technology, near the Virgo Lander II exhibit.
 * Baileys Crossroads, en route to the quest Aiding the Outcasts
