The thor is a huge and powerful mechanical walker. Despite the thor being smaller than the Odin, the thor is still heavily armed and armored, and known to be one of the most heavy and powerful mechanical units in the Imperialist Alliance and the Alliance. Heavy composite neosteel-ceramic armor protects the thor. The plates are modular and can be replaced easily if damaged, or exchanged for thicker versions depending on battlefield conditions. Designed to defeat high-explosive armor piercing rounds, as well as disrupt the searing beams of energy-based weapons, the thor’s plating offers unparalleled protection to the pilot and the mech’s internal systems. Its innermost layer has a heat-resistant kinetic mesh that prevents damage from shrapnel, slugs, or even sheared armor fragments. ATVX has also developed an "immortality protocol," allowing a thor to repair itself in the field as long as its hull remains intact.
