Tony Stark doesn't have a girlfriend in the first Iron Man movie (2008). He is portrayed as a playboy and a workaholic who is more focused on his company and inventions than on romantic relationships. He does, however, have a brief romantic encounter with Pepper Potts, his personal assistant, but it's not a serious relationship.
The movie focuses on Tony's journey of self-discovery and his transformation from a self-centered billionaire to a hero. His relationship with Pepper is more of a professional and platonic one, with hints of a potential romantic connection that will be explored in later films.
