Biography
Stane was a businessman who headed Stark Industries after the death of Stark's father and became the firm's second-in-command when the younger Stark came of age. Stane had cooperated with the Ten Rings terrorists in Afghanistan to kill Stark and take over Stark Industries.

The Ten Rings soon found out who the target was and felt they hadn't been paid enough to kill Stark. They kept him alive to use for their own advantage by having him build them the Jericho missile. Following Stark's return from Afghanistan, he appears to assist Stark's attempt to refocus the company away from arms manufacturing. While Tony is working on his suit Stane starts to take over Stark Industries by sending weapons to both sides of the war.

After Ten Rings finds the remnants of the prototype armor, Stane makes a new deal with them to deliver the prototype to him, but ultimately betrays the group and has them killed, stealing the Mark I armour. While working on building his own, bigger, more powerful suit he discovered that Tony's assistant Virginia "Pepper" Potts found out about his plans so he steals Stark's arc reactor from his chest to power his new suit and leaves Stark for dead.

After Pepper discovers his plans, she and a few S.H.I.E.L.D. agents go to arrest him but they are no match for his new suit. After he is about to kill Pepper, Stane discovers that Tony is alive and has come to save Pepper. The two then duke it out in a final battle over the Stark Industries building. Obadiah easily overpowers Iron Man in every way. In the final moments of the battle, with Stark's power supply running low, he has Pepper overload the prototype large-scale arc reactor found at the complex. Stane is knocked unconscious by the blast, and he with his suit tumble into the generator, causing an explosion that kills him and destroys the armor.
