Fan CastingThe Invincible Iron Man

Tony Stark and Arthur Park worked on an ARC Reactor, an energy source capable of lighting up a city. When Arthur was diagnosed as psychologically unstable Tony fired him and stopped the project, years later he was kidnaped by a group of terrorists lead by a Warlord, they asked him to make him some weapons, but with the help of another scientist called Ho Yinsen that was also being held hostage they built a suit of armor to escape powered up by an ARC Reactor they built. When he returned home he kept using a suit to save people but Arthur recognized the reactor and wanted to get revenge on Tony. He would confront him and try to build another reactor by himself but in the process he would transform himself into the Living Laser and so blaming Tony for it.
