(X-Men I#21) - The six Ultra-Robots were dispatched to Earth along with Dominus to assist Lucifer in his attempts to conquer the Earth. Alpha and Beta captured Professor X of the X-Men when he set after Lucifer, and brought him before Lucifer. Gamma and Delta came upon the other members of the X-Men, and battled the Beast and Iceman. Although the two X-Men managed to overcome them, Lucifer knocked them out by dropping down a barrier in their path.

Gamma and Delta brought Iceman and Beast to Epsilon, who was watching over Angel, Cyclops, and Marvel Girl (whom they had captured in their Cosmic-Crystalline Cube). However, Marvel Girl was able to open the cube using her telekinesis, and Cyclops blasted Epsilon in the back, enabling them to escape. Lucifer heard the alarm, and sent Alpha and Beta to join the others.

The X-Men managed to reach Lucifer before the Ultra-Robots could stop them, but five of the Ultra-Robots soon caught up to them. Delta was destroyed when the Beast dodged his charge and he smashed into a wall. Another was blasted by Cyclops, and the remaining three smashed into an ice shield created by Iceman. With the destruction of the Ultra-Robots, the Supreme One of the Quists recovered Dominus, and sent Lucifer into exile.

(Captain America I#178) - Some time later, when Lucifer was possessing the bodies of the Zodiac member Aries and a criminal named Rafe Michel, the two Lucifers returned to the remains of their base and found three of the Ultra-Robots still operational. They determined to use these robots to aid them in defeating the Falcon.

Zeta, Delta and Epsilon assaulted Harlem to draw the Falcon out, and were able to blast him out of the sky. The Falcon's defeat was witnessed by the then-retired Captain America, Steve Rogers, who donned a ski mask to help his former partner. Delta charged at Rogers while Zeta and Epsilon attempted to block his path, but he darted aside soon enough that Delta crashed into the other two, and all three were destroyed.

Comments: Created by Roy Thomas, Werner Roth and Dick Ayers.

One of the Lucifers claimed that three of his Ultra-Robots were destroyed in X-Men I#21, and the other three were never even used. Let's chalk that up to his memories being divided amongst two people, shall we?
