Named after the zombies of Irish myth, Inner Sphere warriors that first encountered it during the Battle of Luthien called this 'Mech the Cauldron-Born. Ironically, the Clan Smoke Jaguar 'Mech that was intended to replace the Loki was not referred to by its Clan designation, Ebon Jaguar, by other Clans as it was still so new that many Clans just called it by its Inner Sphere designation. It was made to ambush its enemy with a low body, similar to the Lyran Bushwacker, that makes it harder to target. [Source: sarna]
