通过不屈不挠的幸存者们来驯服这些巨大的多刺的爬行动物，我相信最接近棘蜥的已知动物是澳洲魔蜥。除了大小差距明显，大多数棘蜥及其相对较小的差异在于它身上的刺。 这些刺不是它的皮肤永久的一部分，棘蜥背上生长的倒刺更像是可以在脱落之后重新生长的豪猪刺。 事实上，它甚至能够通过从它的尾巴发射这些刺来达到一种自我防御的目的，检查这些发射出去的棘刺显示，它们曾被涂抹过一种致命的毒药。
Common name: Spiny Lizard
Species: Moloch sagittarius
Though survivors have come to call these gargantuan reptiles Spiny Lizards, I believe that Moloch sagittarius' closest known relative is the Australian Thorny Devil (Moloch horridus). Besides the obvious gap in size, most of the differences between Moloch sagittarius and its smaller relative lie in its thorns. Instead of being permanent parts of its skin, Moloch sagittarius' thorns are more like spines or quills that can be removed and regrown. In fact, it is even capable of shooting these spines from its tail as a method of self defense, and examination of these projectiles has revealed that they are coated in a lethal poison.
Despite its dangerous spines, Moloch sagittarius has proven to be an excellent mount for indirect combat. Its ranged attacks can wreak havoc in a pitched battle, particularly if other creatures are taking the enemy's attention. Additionally, Moloch sagittarius is able to gather wood rather effectively, making it more than just an option for combat. Once saddled it can be used as a workbench, allowing for a mobile crafting station.
