Animus Engines are deadly combat mechs designed to only destroy. Invented in 1500a.d. under King Furius of Meowkin, it changed the face of combat forever. Animus Engines were very mobile, customizable, and serviceable. About the size of a two-story building, it allowed for a single pilot to control all movement and functions. At first, most weapons were scaled up versions of smaller personnel equipment, but later specific Animus Engine weapons would be created.

When the Meowkin were the only ones with Animus Engines, they nearly took over the world. King Furius aimed to control everything and only believed in war. Once other empires stole the Meowkin technology, Meowkin reign would soon stall. King Furius was… well… furious and decided to pilot his own Animus Engine into battle sporting two rocket launchers called Commandos, in honor of his human war hero. King Furius was quite successful in battle but his steam would soon run out. He was killed in battle at Litter Mound Top, the bloodiest battle ever seen.

The Animus Engine would advance throughout the years becoming more deadly and ridiculous. They were the best killing machines in the world. Once Lord Midaz came into power and created the Arena Brutalis, Animus Engines were just as deadly, but we're used only as competitive gladiators. This sparked trade between empires, which led to further enhancements for Animus Engines. Animus Engines were the world's stars, everyone loved watching the mechanical monstrosities engage into combat, and to see what new technology they would be outfitted with. When you see someone win using a yoyo, you come back for more.
