Drone: Instead of a complex weapon, he has two robotic wolves with different weapons (one 20mm cannon, one twin 7.62mm MGs) along with a simple but powerful sidearm. Kind of like the techie of the group.

Cybernetics: Born human, but had all of his limbs replaced with cybernetics (like Ironwood) after a horrific accident, and he can replicate weapons (like Velvet, but only certain weapons). He can give these weapons elemental effects using dust tanks built into his robotic limbs (like Weiss' weapon)

Chains: Just figured I'd explain these a little. They are a semblance that are used to restrain creatures and rogue huntsmen and huntresses, and those caught in them can't use any powers like semblances, or Grimm using any healing or strength abilities.
