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

G.I. Robot Mk2 “Mac”

(a.k.a. GI Robot)

  • In the G.I. Robot profiles we’ll attribute 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.
  • This profile is best read after the G.I. Robot Mk1 entry on writeups.org — since important information that is relevant for both generations isn’t repeated here.
  • This profile assumes that “Mac” had capabilities that were at least as good as “Joe”’s, even when not demonstrated.

Powers and Abilities

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

It seemed significantly stronger and smarter, much faster and agile, and actually 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.

The GI Robot dodging gunfire

“Mac” was fast and agile enough that it could 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 – presumably 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 most economical approach is that there was but one “Joe” generation robot, which 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, and Reed and “Mac” had to parachute out, repel a pterosaur attack in mid-air, and finish their descent with but one parachute.

The GI Robot knows karate

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

Shellshocked and hallucinating that his men were calling for help, the crazed sergeant held Reed and “Mac” at gunpoint after they rescued him, being irrationally afraid of the robot.

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 leapt behind the sergeant to grab a carnosaur by the throat before it could attack. Clinging to the dinosaur to save the sergeant, “Mac” used a high-power Suicide Squadron grenade to kill the dinosaur while shielding 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 already almost ready for field tests.


Visually, the “Mac” prototype looks halfway between the “Joe” prototype and the J.A.K.E. prototypes. 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 and 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, which was only briefly on 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.
