Gecko (Fallout: New Vegas)

Geckos are creatures in the Mojave Wasteland

Characteristics
Geckos are found living across the entire Mojave Wasteland, including normal, golden, and fire variants. Fire Root Cavern is considered to be the origin of fire geckos. Another variety, the green gecko, is found in Zion Canyon.''.

Geckos are found in small packs and use melee and bite attacks. Some variants of gecko can breathe fire or spit a poisonous liquid as a ranged attack. If the Courier's Survival skill is high enough, they can tan the hides at a campfire. Once tanned, they can be used to craft armor that offers greater defense and resistance to fire, poison, and radiation.

Geckos, green geckos, and golden geckos are classified as animals and are affected by the Animal Friend perk. Fire geckos are classified as abominations and remain hostile to the Courier. This means that fire geckos will flee if shot with a flare gun.

Gecko
Geckos can be found in the areas surrounding Goodsprings, along the I-15 towards Primm, and around the Mojave Outpost. These are the least dangerous species of gecko found within the Mojave.

Gecko hunter
Gecko hunters look identical to normal geckos but have greater health and speed. They are fast and will attempt to rush and overwhelm their prey by attacking in groups.

Young gecko
They are smaller and cause less damage, but share the same behavior as adults and may appear with them in packs.

Young gecko hunter
Although appearing as hostiles on the compass, they often ignore nearby creatures unless provoked.

Golden gecko
The golden variant are found around irradiated areas such as Crescent Canyon east and Crescent Canyon west, Vault 34, Cottonwood crater, and the Searchlight church basement. Their attacks inflict radiation damage.

Golden gecko hunter
These geckos may appear alongside golden geckos and attack in the same way. Their bites are similarly irradiated, dealing less radiation per second but for a longer period of time. Golden gecko hunter melee attacks do similar damage to regular golden gecko melee attacks.

Young golden gecko
They are seldom found alone and are usually found with adult geckos.

Fire gecko
Fire geckos have the ability to breathe fire. They are found in and around mountainous areas and caves, such as the Lucky Jim Mine and Nopah cave.

Young fire gecko
These geckos can breathe fire and attack alongside adult variants.

Legendary fire gecko
The legendary fire gecko is one of five legendary creatures. It is larger than a normal fire gecko. It is found in Fire Root cavern.

Green gecko
Green geckos are only found near waterways and bridges in Zion Canyon. When attacking from a distance, they can spit several far-reaching but slow-moving globs of poisonous saliva, somewhat resembling the radioactive spit attack that centaurs use. Once in contact with an enemy, they will attack like other types of gecko, by biting and clawing. Green geckos are almost always found in packs ranging from two to eight.

Young green gecko
They are smaller and weaker than adults but spit poisonous saliva and attack in the same way. They are only found in Zion Canyon.

Giant green gecko
These green geckos are large and have almost the same destructive power as the legendary fire gecko.

Gojira
An unused creature available only by console command. When spawned, the large variant is labeled as a generic gecko with the editor ID "Gojira." It has its own unique embedded fire breath weapon called 'Gojira Flame' (formid 0011324a) which has a base damage of 400, 8000 HP, and a damage per second of 3200.

Appearances
Geckos appear in Fallout: New Vegas.

Behind the scenes
"Gojira" was not intended for inclusion in the game and was created by one of the developers as a Godzilla joke.

Bugs

 * Geckos may not always be hostile to the Courier, even if the player character doesn't possess the Animal Friend perk. However, getting too close or trying to speak to one may turn it hostile.
 * Green geckos inhabiting Zion Canyon may not be hostile to the Courier, and approaching or attempting to talk to them will not change their disposition. If the player character happens to shoot one of these geckos, simply put away one's weapon and it will return to being friendly, just like a normal non-player character.
 * In the Mojave Wasteland, several young gecko hunters may be found superimposed upon one another, but not moving from the spot except to flail their arms and roar loudly. They cannot be damaged with guns, and when attacked and killed with a melee weapon, the game freezes and must be reset.
 * Geckos around Goodsprings source may spawn inside of rocks.
 * When a fire gecko's head is shot, flames will shoot out as if it were attacking.

Sounds

 * Idle gecko
 * Gecko in pain
 * Snarling gecko
 * Flame throwing gecko
 * Flame burst
