Blade Wolf, or simply Wolf, officially designated IF Prototype LQ-84i (IF standing for "Interface"), is a wolf-like quadrupedal Unmanned Gear with a learning optical neuro-AI and a prototype verbal interface. Known weapons systems included a chainsaw attached to his back that could be used to cut opponents, springloaded HF knives, as well as extendable claws. His tail also acted as a manipulator arm similar to that of the Gekko units. It was once referred to informally as the K-9000 due to its appearance, which also resembled the battle suit of Crying Wolf. Similar unmanned gears called Fenrirs existed as well, apparently being mass-produced models of LQ-84i.

Blueprints for LQ-84i were downloaded into Raiden, an agent for the PMSC Maverick Security Consulting, Inc., during or prior to being severely injured in a mission. Maverick later recovered the cluster file via Raiden's arm, although they not only had to input a password to bypass the encryption process, but also enact an override system in the process.
