Paul Norbert Ebersol was born in Dayton, Ohio. He was a scientist who held a number of odd jobs, including auto mechanic, television repairman, and electronics laboratory assistant. He then became the second and more prominent "Fixer", a supervillain and genius-level criminal inventor who has often worked for criminal cartels like HYDRA. In his first appearance, he escaped from prison, teamed with his partner Mentallo in an attempted takeover of the New York S.H.I.E.L.D. headquarters, and even captured Nick Fury. Fixer and Mentallo were defeated by Tony Stark and S.H.I.E.L.D. troops.
