Mister Gutsy Mister Gutsy is a robot that appears in " Fallout 3 " , " " and " Fallout 4 " . Background . < section begin = " Background " / > Mister Gutsy is a line of military robot models created by General Atomics International . It is a militarized version of the Type - I Mister Handy , an earlier civilian model robot created by the same company for use in household duties . The Mister Gutsy , unlike the Mister Handy , is a dedicated combat robot and is easily distinguished from the Handy model by its military olive - drab paint job , WWII - era U . S . Army roundel insignia , improved weapons and the replacement of its British butler voice with that of an American drill sergeant . This model was commissioned by the U . S . Army just before the Great War in 2077 . They have distinctive " soldierly " personalities , with an advanced AI somewhat similar to that of the Mister Handy model . More likely than not , due to the conflict with China that caused the Great War , Mister Gutsies often scream anti - communist phrases , similar to Liberty Prime . Mister Gutsies also have a more " gung - ho " patriotic personality compared to the other combat robots in the Commonwealth . < section end = " Background " / > Variants . Mister Gutsy . Mister Gutsy is the second most dangerous robot in the Mojave and Capital Wasteland s , trailing behind sentry bots . Gutsy models are armed with a plasma gun , roughly equivalent to a plasma pistol , for long - range combat . At close - range , the robot relies on its flamethrower . This affords the 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 Gutsy . 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 menacing deep red . Strike team Mister Gutsy . This model of Mister Gutsy is added in the " " add - on as a possible Strike team member . Brotherhood Outcast Mister Gutsy . 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 Gutsy . It ' s speculated that , considering their exclusive location and unconditional hostility , these unique robots were designed and / or programmed specifically to protect the Tesla - Beaton prototype en route to wherever it was being transported before the crash ; by this logic , it can be assumed that the skeletons found in the crash site were not members of that Vertibird ' s crew , because of their appearance outside the craft and only with the Tesla - Beaton prototype . This theory is reinforced by the fact that there is no disguise , not even the Enclave - friendly Remnants power armor , that will cause them to be neutral / friendly . Mister Gutsy prototype . Not much is known about the prototype series , but it can be assumed that these robots were commissioned by the US Army to test and evaluate the capabilities of a combat version of the existing Mister Handy . This series was commissioned some time before the production series for trials , which were obviously successful as the production models were brought into service shortly before the Great War . The prototypes were likely phased out in favor of the slightly improved Production Version , and appear to have been either mothballed before the bombs fell , or deactivated due to long service without maintenance . In either case , 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 series . The Mark series of Mister Gutsy robots only appear in the " " add - on " Old World Blues " . The atomic apocalypse had prevented them from entering service .
