Geckos are reptilian in appearance and sport a pair of frills behind their head. 牠们有着橙色的眼珠，皮的颜色根據品種有不同差别，上下肢都有5个趾头，并且保留了战前那种通过鸣叫沟通的能力。和战前一样，牠们没有眼皮和泪腺，因此只能用长长的舌头去舔眼睛，清洁灰尘并保持湿润。一般说来，蜥蜴是一种不那么麻烦的生物，攻击性也不算很强，不过只要有一只蜥蜴卷入战斗，附近所有的同类都会过来帮助撕咬敌人。
The regular gecko is a small-medium sized gecko with indigo skin. Like their cousins the silver geckos, they are mostly peaceful but tend to be rather aggressive in groups. They are very quick on their feet and are fond of using their numbers to rush and overwhelm the opponent.
銀 / 小蜥蜴编辑
The silver gecko, also called little gecko, is a small-sized gecko with silver skin. They are the smallest and least aggressive of all geckos and are not very resistant to damage. They have thus far only been observed in southern Oregon.
金蜥蜴 编辑, making their hides far more "glamorous" than any other kind of gecko, and making their attacks irradiate the opponent. They can be found in southern Oregon and in the Mojave Wasteland.
The fire gecko is a medium-large sized gecko，表皮为紫色，长着尖刺。They are the second deadliest kind of gecko after the green gecko and, as indicated by their name, 拥有“火焰吐息”的能力。Unlike other geckos, they also have large spikes or decorative frills that cover their heads down to their lower back. They are immune to fire and their hides are far too mangy or burned to have any true value. They can be found in northern California and in the Mojave Wasteland.
The green gecko is a large gecko with shiny light green skin. They are the most deadly of all geckos and 能够吐出毒液进行远距离攻击similar to centaurs. Despite their fragile appearance, they have a high resistance to damage. The cause of their mutation is currently unknown, though some theorize it might be due to ingestion of poisonous plants native to Zion. 牠們是锡安公园的本土种群。
- In Fallout 2, the quest perk Gecko Skinning allows the player character to skin silver gecko and golden gecko (not fire gecko). In Fallout: New Vegas, one is able to take the hide of any kind of geckos directly, and if their survival skill is high enough, they can tan the skin at a campfire.
- In Fallout: New Vegas, 普通蜥蜴、绿蜥蜴和金蜥蜴都受到动物之友(除了火蜥蜴)、Animal Control和Hunter特技的影响。
- Green geckos were first planned to appear in Fallout d20 before finally appearing in the Fallout: New Vegas add-on Honest Hearts.
