Blade Wolf, officially designated IF Prototype LQ-84i, (IF standing for "Interface"), also known as Wolf, and once referred to informally as the K-9000 by Kevin Washington, is a quadrupedal robot with a learning optical neuro-AI and a prototype verbalinterface, resembling Crying Wolf's beast form. Known weapons systems included a chainsaw attached to his back that could be used to cut opponents, springloaded HF knives, a rail gun, as well as extendable claws. His tail also acted as a manipulator arm similar to that of the Gekko units. Similar unmanned gears called Fenrirs existed as well, apparently being mass-produced models of LQ-84i.
