A Ultron Sentinel is a drone replica of the nihilistic android Ultron. Hundreds of Ultron Sentinels were used by Ultron to launch a full-scale mechanized invasion of Earth.[3]

Ultron Forever (Earth-14831)

After destroying the Avengers, Ultron created factories that relentlessly built Ultron drones to expand his empire.

As part of a plan to take over Ultron's reign, Doctor Doom assembled a team of Avengers from different points in time, and had two of them, Vision and Iron Man, assault the Avengers Tower, the location from where all of Ultron's drone factories were controlled.[4]

Vision and Iron Man successfully accomplished their mission, believing to have destroyed the power source of the factories. However, Doom had lied to them, and what they had destroyed was actually the security systems, allowing Doom to hack into the factories and gain control of Ultron's army, retrofitting the drones to his own image.[5]

Ultron Sentinels from Uncanny Avengers Ultron Forever Vol 1 1 001

Following Ultron's defeat, Doctor Doom used the newly-aquired army to hunt down the time-displaced Avengers, who had escaped before Doom could send them back to their time periods. After finding themselves surrounded by a neverending army of sentinels, the Avengers took the fight to Doom, and convinced him to free the Earth.[6]
