Repeat, will you comply?— Mister Gutsy

Mister Gutsy is a type of robot that appears in Fallout 3, Fallout: New Vegas, Fallout 4 and Fallout 76.


A dedicated combat variant of their civilian Mister Handy, the Mister Gutsy series was developed by General Atomics International.[1] It was commissioned by the United States Army shortly before the atomic apocalypse of 2077,[2] with the first units seeing service in the liberation of Anchorage in January.[3] The Mr. Gutsy is a personal protection automaton and comes equipped with heavier armor than most utility robots. It also carries a plasma weapon to be used in defense. The shell was rebuilt with lightweight armor plating, while the usual array of tools was upgraded with a plasma caster on a flexible mount. The key advantage of Mister Gutsies that separates it from other combat robots is its sheer maneuverability and spatial awareness.[4][5] The Mister Gutsy is also upgraded with dedicated military software, including the ability to refuse orders issued by commanders who are incompetent or under court martial,[6][7] remote link-up capability for updating orders in real time,[8] and a brand-new Sergeant Major v.1.0 simulated personality that channeled the stereotypical Marine drill instructor and doubled as a vessel for state propaganda.[9]

However, in its rush to present the Army with a working model, General Atomics cut corners and the resulting personality had issues stemming from vague definitions used in programming its neural network.[10] The most notable of these was the fact that in the absence of orders, units defaulted to a patrol mode and attacked all unauthorized personnel with extreme violence, as per combat protocol Charlie Zulu 4.[11] The military accepted these flaws, pressing them into service. They first bore MGZ-##### serials, before transitioning to the standard ABC-##### nomenclature.[12] To distinguish between different variants of the robot, ranks were used: The baseline version was named Mister, with subsequent variants designated Sergeant, Lieutenant, Major and Colonel.[13] A specialized field medic model was derived from the basic Mister Gutsy, with all combat functionality disabled[14] and an encyclopedic knowledge of medical procedures, particularly surgery.[15]


Mister GutsyEdit

Mister Gutsy

Mister Gutsy is one of the most dangerous robots in the wasteland, just behind assaultrons and sentry bots. Mister Gutsies are armed with either a plasma gun, roughly equivalent to a plasma pistol[16], 10mm submachine gun or a .44 pistol[17] for long-range combat. At close-range, the robot relies on either a flamethrower or a buzzsaw, however higher "ranked" models sometimes have both. This affords the Mister Gutsy decent protection against both ranged and melee targets, a feature lacking in any other robot save the civilian Mister Handy. Additionally, due to their hover mechanism, Gutsy units do not set off the proximity fuses on mines.

Enclave Mister GutsyEdit

Gameplay articles: Fallout 3, Broken Steel

The Enclave Gutsies are very similar to their free roaming wasteland counterparts, with the exception of its paint scheme. Instead of the normal matte olive green of the U.S. Army Gutsies, these feature a dark metallic color. Its optical sensors also differ from the standard yellow, instead being a deep red.

Strike team Mister GutsyEdit

An unused Mister Gutsy creature with the editor ID 21ec0 is related to the Outcasts, however it just wears the regular green US Army skin. However, in the game files there is a connected skin for this Gutsy without a model.

Hardened Mister GutsyEdit

These unique Mister Gutsies can be found guarding the crashed vertibird in the southern Mojave, along with hardened sentry bots. Their HP exceeds a regular Mister Gutsy's by fifty points, and their general toughness is on par with the average sentry bot, accredited to their 10 Strength attribute (double that of the average Mister Gutsy).

Mister Gutsy prototypeEdit

Not much is known about the prototype series. This series was commissioned sometime before the production series for trials, which were obviously successful as the production models were brought into service shortly before the Great War. They appear to have been salvaged by prospectors and reprogrammed for use by private individuals, such as the one located in a house in Nipton.

Mister Gutsy Mark seriesEdit

Mister Gutsy

The Mark series of Mister Gutsy robots only appear in the Fallout: New Vegas add-on Old World Blues. The atomic apocalypse had prevented them from entering service.

Notable Mister Gutsy unitsEdit

Behind the scenesEdit

Dave B. Mitchell, who voiced Mister Gutsies in Fallout 4 and Fallout 76, took inspiration from R. Lee Ermey in his performance.[18]


  1. Fallout 76 loading screens: "Realizing their robots' enormous military potential, General Atomics International developed the Mister Gutsy as a powerful wartime equivalent to the Mister Handy."
  2. Fallout 3 loading screens: "The Mister Gutsy model of robot was commissioned by the U.S. Army just before the atomic apocalypse of 2077."
  3. Operation Anchorage
  4. Fallout 3 and Fallout: New Vegas loading screen: "Mister Gutsy is a combat variant of the popular Mister Handy, and is equipped with a Plasma weapon and flamethrower."
    (Fallout 3 loading screens, Fallout: New Vegas loading screens)
  5. Fallout 4 loading screens: "The Mister Gutsy was created by General Atomics International as a combat alternative to its domestic Mister Handy robot."
  6. The Lone Wanderer: "Time to head back into the fight, RL-3."
    Sergeant RL-3: "Sir, I regret to inform you that this unit cannot accept orders from an irresponsible officer!"
    (Sergeant RL-3's dialogue)
  7. The Lone Wanderer: "Time to head back into the fight, RL-3."
    Sergeant RL-3: "Sir, I regret to inform you that this unit cannot accept orders from an officer under a Court Marshall!"
    (Sergeant RL-3's dialogue)
  8. MilitaryRobotTalk: "Sergeant Major reporting for duty... downloading orders from Central... FAILURE."
  9. MilitaryRobotTalk: "Loading Personality: General Atomics International V1.0 "Sergeant Major"..."
  10. The Lone Wanderer: "I'd like to buy a robot."
    Tinker Joe: "Of course you would, of course! Well, it just happens that I've got a beaut of a deal on this customized Gutsy. And it's not just "Mister" Gutsy - he's a full fledged sergeant! "Sergeant RL-3" to be precise, the pride of General Atomics International. Comes complete with a simulated personality unit, so he's good protection and good company, too! And all yours for just 1000 caps."
    The Lone Wanderer: "Simulated personality? Sounds like trouble."
    Tinker Joe: "To tell the truth, it is a little trouble. But he can't help the way he got built. General Atomics programmed the Mister Gutsy to be a good soldier, but their definitions were a bit vague. So a lot of units had... issues. So we got a gung-ho, robotic soldier that's picky about the company he keeps. But he seems to like you, so it'll be fine."
  11. MilitaryRobotTalk: "Halt, intruder! Unauthorized personnel will be handled with extreme violence. Initiating Combat Protocol: Charlie Zulu 4."
  12. Serial numbers as presented in the games starting with Fallout 3, through Fallout: New Vegas, and into Fallout 4.
  13. The companion Sergeant RL-3 in Fallout 3 and the naming of the variants of Mister Gusties in Fallout 4.
  14. The Lone Wanderer: "Say, could I reprogram you to kill people?"
    Sawbones: "Negative. The Mister Gutsy field medic model is incapable of harming human beings through intentional action."
    (Sawbones' dialogue (Fallout 3))
  15. Fallout 3 Official Game Guide Game of the Year Edition p.95: "Sawbones
    This is a modified Mister Gutsy with an almost encyclopedic knowledge of surgery, but it lacks the necessary medical subsystem knowledge to carry out operations without causing inadvertent harm to the patient. Recently, Sawbones has been exhibiting some worrying behavior, including having a penchant for poetry."
    (Fallout 3 Official Game Guide Game of the Year Edition Wasteland Census)
  16. Capital/Mojave Wasteland models
  17. Commonwealth/Appalachia models
  18. Kal-El Bogdanove on Twitter: "The default mr gutsy voice and personality type comes to attention courtesy of @davebmitchell who based the voice print in part on the great R. Lee Ermey."
