Bitten by a genetically-enhanced acorn, Francois Noyer took on all the abilities of a nut (most notably a tough outer-shell and causing severe irritation to those with nut allergies). He has since vowed vengeance on all nuts, seeds, and legumes. Noyer (now called The Nutcracker) won't stop until he brings justice to the mutated acorn that made him into the nut he is today.
