Monkeywrench enjoys two things; constructing mechanical monstrosities, and destroying things with aforementioned mechanical monstrosities.
Her parents own the third largest scrap yard in the solar system so Monkeywrench grew up as junkyard royalty.
She showed an early aptitude for technology, disassembling and reassembling the droids, ships and mechs that were dropped off to be scrapped.
She is a brilliant tinkerer and enjoys building her own (sometimes useful, often bizarre) creations from the parts she salvages.
Her pride-and-joy creations are her trademark mecha-gauntlets, retrofitted with Konn-Gen anti-grav stabilizers, they feel as light as a feather, but are strong enough to crush a starship down to sheet metal.
She has made a name for herself as one of the best mech technicians in the galaxy and mech and tank pilots from all over come to her for repairs or retrofits.
When Monkeywrench heard about the Khrysos Hunt, she looked around at her humble junk-strewn surroundings and realized that the Khrysos Treasure would give her the opportunity to improve her lifestyle and give her the elaborate junk-strewn future she always dreamed of.
