Fire gecko (Fallout: New Vegas)

Fire geckos are creatures found in Mojave Wasteland. They are the largest and most dangerous form of gecko. They also spew flames from their gullet.

Characteristics
Fire Geckos are considered the worst of a very bad lot. Whilst regular Geckos run the gamut from pathetic to nuisance, and Golden Geckos vary between annoying and threatening, the Fire Gecko is the first species you will encounter that is tactically known to be dangerous. The biggest and strongest Gecko by no small margin, Fire Geckos are easily recognized by their spike-covered bodies, mottled purple-and-red hides (which are widely prized by trappers for making armor) and their most infamous contribution to their namesake: that they can breathe fire. It is hinted that they get their fire-breathing capability from constant exposure to sulfur, due to the fact that there are many fire Geckos in the sulfur caves of Vault 19.

Like all Geckos, Fire Geckos are highly resistant to fire and are vicious if they can close the distance. In addition to their infamous fire breath, which is devastating to lightly-armored foes, they possess by far the most powerful and effective melee attacks of any subspecies of Gecko. A single adult Fire Gecko can easily defeat an unprepared low-level character if they do not take precautions. They frequently waddle about, but are very fast-running once they are provoked and they know an enemy is near.

Fire Geckos are also the most intelligent species. They frequently will try to spread out, as to minimize the damage of explosions and maximize the chances that one of their number can get within melee/fire breath range. They are the only Gecko subspecies not effected by the Animal Friend perk, and they will not be friendly towards the player under any circumstance as a result.

Atomic Cocktails and Fire Ant Nectar are both useful for taking a notable cut out of their attacks. Med-X can help cut their fairly high melee attack damage.
