A bloatfly is a mutated blowfly with a green-brown carapace. Unlike the identical Capital Wasteland variant, bloatflies in the Mojave are largely docile, and are seen as rather territorial and far less common. They are usually found around graveyards or pools of radiated water in groups of three to five.
Weak by nature, their attacks have very little effect. Their main attack consists of spitting spiked larvae from a distance. They are relatively easy to kill in close combat, even should the attacker lack any substantial skill in Unarmed or Melee Weapons, as they have very little HP. However, it can be a bit tricky to hit them with a ranged weapon without the assistance of V.A.T.S., as they tend to move rapidly and in sporadic patterns.
Unlike most other inhabitants of the Mojave Wasteland, bloatflies will often leave other creatures alone if they walk away and ignore them.
A legendary variant can be found in Big MT, at the mysterious cave. It is considerably larger than a normal bloatfly, and has a pale green aura, making it easy to spot in the cave. It also flies much higher, making striking it with melee weapons difficult or entirely impossible. Unlike normal bloatflies, it fires a highly damaging plasma-like projectile from its abdomen, the strength of which is such that even the strongest of attackers will be killed after just a few shots. When killed, it explodes in a manner similar to a plasma grenade, leaving a goo pile instead of a corpse. Its brain can be targeted in V.A.T.S., and if crippled, will cause it to frenzy. Like Gabe, the legendary bloatfly's immense size is suggested to be the result of a massive intake of chems, notably Buffout and Psycho. It has twice the health of the legendary deathclaw, and deals nearly twice the damage.
