G.I. Robot Mac (DC Comics) (War That Time Forgot)

G.I. Robot Mk2 “Mac”

(a.k.a. GI Robot)

Power Level:
Game system: DC Heroes Role-Playing Game


This profile is intended to be read directly after the G.I. Robot Mk1 “Joe” character profile. This is the one with the context.

In the G.I. Robot profiles we assign a Mark to the successive robots (Mk1, Mk2, etc.). These numbers were not actually used in-universe. They are writeups.org labelling so readers can easily tell in which order the robots were deployed.

Powers and Abilities

“Mac” is a metallic android. He’s a heavier, more powerful variant over the basic “Joe” design of G.I. Robot.

It seemed significantly stronger and smarter, as well as much faster and agile. The Mk2 demonstrated that it was immune to gunfire (at least .45 ACP at close range) – which hadn’t been clearly established with the Mk1 G.I. Robot.


“Mac” was fast and agile enough to be programmed to fight using basic Japanese martial arts known to Americans in the 1940s – judo and karate.

There’s an automatic gun in its right hand. It presumably is a rebuilt .45 M3 “Grease Gun” submachinegun, with an ammunition bin inside the robot.


Like with the previous G.I. Robot prototype (the “Joe” model), it is not quite clear whether the “Mac” model was the second or the first prototype of its generation. The dialogue is ambiguous.

The GI Robot dodging gunfire

The most economical approach is that there was but one “Joe” generation robot. It was lost in combat along with its human handler, a US Army Ranger and Suicide Squadron veteran named Mac.

In this hypothesis, the second generation prototype — developed within a month or so of the earliest field tests for “Joe” — was named “Mac” in honour of “Joe”’s handler.


The researchers again had a field handler assigned to the project. Like Mac before him, Reed was a US Army Ranger and a veteran of the Suicide Squadron. The tests were to take place in the Mission X area, presumably to preserve secrecy.

As usual things went wrong when giant pterosaurs attacked the transport plane. Reed and “Mac” had to parachute out, repel a pterosaur attack in mid-air, and finish their descent with but one parachute.


After getting rid of a sort of brontosaurus, Reed and “Mac” attempted to rescue other survivors from the plane. Another objective was to recover the parachute-equipped tank. They were slightly too late. Only the tank sergeant was still alive after a mega-carnosaur attack.

Hallucinating that his men were calling for help, the crazed sergeant held Reed and “Mac” at gunpoint after they rescued him. Being shellshocked, he was irrationally afraid of the robot.

Robot sacrifice

This standoff was broken by “Mac”’s heroic action. The G.I. Robot shoved Reed aside to save him from the sergeant’s gunfire. Then it leapt behind the sergeant to grab a carnosaur by the throat before the beast could attack.

Clinging to the dinosaur to save the sergeant, “Mac” used a high-power Suicide Squadron grenade to kill the dinosaur. The robot shielded the two humans from the blast with its body.

Reed could only bring back the intact head of the G.I. Robot. But a third generation of G.I. Robot, called J.A.K.E. (Jungle Automatic Killer – Experimental) was almost ready for field tests.


Visually, the “Mac” prototype looks halfway between the “Joe” prototype and the J.A.K.E. prototypes.

The GI Robot knows karate

Unlike the “Joe” prototype it doesn’t operate in uniform. It is naked except for a standard-issue US steel pot helmet, presumably chosen since it was easier and more convenient than building a fully armoured skull with an access hatch.

“Mac”’s servos often emit a not-so-faint whirring noise.


The “Mac” G.I. Robot cannot speak or emote. But like “Joe” it is determined to protect allied humans . Even at great risk to itself, and even if it wasn’t ordered to.

Though “Mac” is best used by giving it clear orders, it has extensive interpretative capabilities. It is programmed to have a solid initiative level in applying the military buddy system . It always keep an eye out for its buddy — its human handler — and will protect and assist him like a real G.I. would.

“Mac” may have had memories downloaded from “Joe”. For instance it understood what Reed wanted it to do when he presented his hand for “Mac” to shake.

It is possible to interpret the story with the “Mac” robot actually holding the consciousness of the deceased Mac — “Joe”’s handler — within its responsometer. This interpretation chiefly stems from a much, much later version of responsometers working by integrating the consciousness of dead humans. And this was only briefly in continuity.

Marvel Universe History

In the Marvel Universe, the stolen designs of the “Mac” generation robots could have become the basis for the Dreadnought combat robots of the 1960s.

Design Notes

This profile assumes that “Mac” had capabilities that were at least as good as “Joe”’s, even when not demonstrated.
