Obadiah (Jeff Bridges) takes Tonys (Robert Downey Jr.) second version of the artificial heart used to power the suit (and thats used to keep himself alive) and uses it to power another suit that was recently built at Stark Industries. Tony battles Obadiah in his suit using the first version of the artificial heart. Tony asks Pepper (Gwyneth Paltrow) to overload Stark Industries arc reactor and Obadiahs suit malfunctions and falls into the reactor. The next day, at a press conference, instead of covering up the truth by saying that someone in an armored suit is his bodyguard (nicknamed by the press Iron Man), Tony reveals that he is Iron Man. A few minutes into the end credits, Tony arrives home and notices that someones sneaked inside his home. He asks the mysterious person who he is and its Nick Fury (Samuel L. Jackson) who is the director of S.H.I.E.L.D. (the organization that wanted to talk with Tony Stark, throughout the movie, about how he escaped captivity in the mountains and the ones who helped cover up the arc reactor explosion). Fury says to Tony that now that hes revealed to the world that hes Iron Man.. hes stepped into another world he didnt know existed. Fury tells Tony that he wants to talk with him about a project called The Avengers Initiative...
