A commission for featuring the cast of his fic Fallout Equestria: Morality of Property. Also a fun, quirky fic I reccomend giving a look.
Characters from left to right: Top Notch, Shimmercoat, MG-MS11, Coin Slot, Crescent Wrench, Hiss, Matchstick Flare ( I did not forget a horn. she is an earth pony)
Yes, it's a MEDI (Medical Extraction and De-fragmentation Injector) Gun, wielded by a robotic doctor. There were even TF2 references made while he was using the gun.
i have not read this fic, but i looked up the name for the mr handy and he is a medical bot, so i am assuming that is suppose to be a medigun and the visual he used what the one from tf2, so yeah
