Mechanical Prototype Panther MK-0
When Gadgetzan citizens pried open Gazlowe palace's underground lab, caged beasts' roars were suffocating. Undermine tech fused combat modules onto these panthers, granting superhuman strength and speed. Rustbolt engineers reprogrammed them exclusively for warriors campaigning in K'aresh. Remember to swap modules at the Morphing Forum before deployment.
