Shadow Foe

Description
Shadow Foe is the spirit of an enormous axe that can be used for both combat and execution, manifesting as a dark figure resembling a voodoo doll with ragged hair.

Powers and abilities
Shadow Foe, despite what her owner Shadow Boss believes, is the true master of the axe she inhabits, and can easily wrest control of it from him at a whim. Despite being entirely incorporeal, she is able to lift and control the axe with little effort. The axe is naturally dangerous to enemies as a giant weapon, but is also unique as it damages spirits and incorporeal beings just as easily as it does physical creatures.

History
Shadow Foe grew in power with every execution that Shadow Boss performed in life, absorbing the power of the victims she was used to kill. Eventually, she amassed enough power to manifest herself and betray Shadow Boss, and threatened to destroy him as well as the rest of the world, only being stopped in time by the Fighting Polygon.
