Matrix-Prime (Supergirl enemy) (DC Comics)



This powerful giant robot has no known link to other characters called Matrix. He first appeared in 1983.

Matrix-Prime only appeared (almost) as an enemy of Supergirl during the mid-1980s. This is sometimes called the Daring New Adventures era, after the title of Supergirl’s book back then.

Powers and Abilities

Matrix-Prime is, as he’s prone to boast, built out of “Tylenmium alloy, resistant up to 12 million pounds per square-inch pressure”. In other words, he was able to withstand blows from Supergirl without apparent damage. Still, she eventually managed to tear off one of his arms.

Matrix-Prime also proved strong enough to swat her, fast enough to surprise her with his moves several times, and able to fly at supersonic speeds.

A robot that shoots robots

Asides from this raw power, Matrix-Prime is a walking robot factory. He can build robots within himself. In game terms this is modelled as two types of chassis he carries as equipment, onto which he can affix additional equipment.

For instance, a standard worker chassis with a blaster becomes a combat drone. Or a missile chassis with a weakness detection array becomes a probe flying around his target. Equipment built on the spot is represented by Omni-Gadgets – especially if said equipment is intended to exploit the weaknesses of his opponent.

In DC Heroes RPG terms, by using the Split Power on his Equipment, Matrix-Prime has (1×6=6) worker chassis he can equip in various manners. He also has (3×6=18) mini-missile chassis he can likewise equip as he sees fit. He used this arsenal against Supergirl in waves. If fighting a group he might instead grab raw materials for his factory and produce everything at once.

Matrix-Prime’s robots emerge from a round hatch on his chest. When their mission is done they fly back in to be disassembled and reused for parts as needed.



Matrix-Prime is one of the greatest known achievements of a shady, villainous organisation called the Council. Though building the large bunker on the floor of Lake Michigan, which was the base from which Matrix-Prime was launched, was presumably quite a feat too.

Very little is known about the Council, as it values secrecy above everything. Employing superhuman agents is not their usual style. It was an idiosyncrasy of their Chicago branch director, Mr. Adams. For drawing the attention of Supergirl by hiring the Gang and then having Matrix-Prime appear in broad daylight, he was executed by the remainder of the Council.

(This Council has no known connection to the Council that fought Manhunter or Nemesis (Soseh Mykros), or to the Council that fought Nemesis (Tom Tresser).)

Matrix-Prime itself finished the job the Gang started. He stole more expensive satellite components to put the newest Council satellite into orbit and achieve global power.

Much like the Gang had succeeded despite Supergirl’s interference, Matrix-Prime recovered the target parts by attacking the Chicago International airport. He let his worker robots carry off the needed part from the airplane they were in. Matrix-Prime then flew away, launching two powerful missiles at the skyline so Supergirl would be distracted from flying after him.

Howbeit, Supergirl kept tracking him through super-hearing. She quickly flew back and dove underwater after the robot, thus discovering the Council’s Chicago base. She promptly thrashed most of it, though in the process she encountered Matrix-Prime again.

All this and Brains too, part 1

This time, the robot was under the domination of Brains, the leader of the Gang, who used a cybernetic tiara. Matrix-Prime, under the guidance of Brains, got in a telling blow. But Supergirl hit the robot so hard that the feedback sent Brains into a coma, which left Matrix-Prime inert.

However, the incident enabled Brains to take permanent control of Matrix-Prime. After bursting her meat body out of prison with her metal body, Brains/Matrix-Prime decided to remain allied with the Council and fight Supergirl once again. Her goal was to capture her for the Council’s newest experiment.

Brains/Matrix-Prime broke into a museum to attract Supergirl’s attention. She then easily defeated her, as Supergirl had previously been greatly weakened by radiation from Reactron.

All this and Brains too, part 2

Supergirl and Matrix-Prime had an opportunity for a rematch when criminal billionaire Burrough drew on Council resources, including Matrix-Prime and Brains. The goal was to prevent a book about him to be published. The fight between Matrix-Prime and Supergirl was brief, however. By then, Supergirl was growing experienced in fighting the powerful robot.

She used her heat vision to fuse his chest hatch shut, preventing him from releasing robots. Supergirl then punched the weakened metal and took Matrix-Prime apart within less than a minute.

However, this happened on Burrough’s island, deep in the middle of the Atlantic. Thus, it is likely Brains managed to escape and have Matrix-Prime rebuilt.

“Affirmative, humans. Your weapons are useless… against Matrix-Prime !”

“That statement is non-functional. Worker drones have reached prime-coordinates… as Matrix-Prime must do now.”

(Brains piloting Matrix-Prime) “I am so pleased we have the opportunity for a rematch, Supergirl ! I detested leaving you alive in Chicago !”

Design notes

As with all DNAOS characters, this Pre-Crisis character is written up on Post-Crisis scale.

OK, so the semi-clever Split trick is prolly munchkinny. But it *does* model the character. I’m, uh, split on the matter.

Matrix-Prime reloaded

At first, Matrix-Prime was built to operate in the air or underwater. Thus, he didn’t have legs – just exhaust tubes where the upper half of his upper legs would have been. The legs didn’t appear until his last appearance.

For a few Phases, Matrix-Prime also acted, not as an independent entity, but under the direct mental control of Brains, the leader of the Gang.

Brains commented that it was no wonder the robot’s programming made it an inefficient opponent against Supergirl, but that her direct control would correct for that. In game terms, this simply means that she could spend HPs to support what was at that point her Gadget through the magic of cybernetic interfacing.

This incident marked the accidental creation of a permanent telepathic link between Brain and Matrix-Prime. From that point on, Brains could direct Matrix-Prime’s action and speak through him, as well as spend HPs. She basically had two bodies and could transfer her personality from one to another.

Matrix-Prime, however, no longer had any HPs of his own. See the Brains writeup for details about her and her link with Matrix-Prime.

The Matrix-Prime body with Brain riding it has the following Attributes:
