Agent 99 is a character in the 2008 action comedy film "Get Smart," played by Anne Hathaway. She is a highly skilled and experienced field agent for the spy agency CONTROL, and is paired with the bumbling analyst Maxwell Smart (Steve Carell) to stop a villainous plot.

Throughout the film, Agent 99 is portrayed as a strong and independent character, capable of holding her own in combat and outsmarting her opponents. She is also shown to have a dry sense of humor and a no-nonsense attitude, which provides a good contrast to Smart's more comedic and clumsy personality.

As the story progresses, Agent 99 and Smart develop a professional respect for each other and eventually a romantic relationship. This relationship adds a romantic subplot to the film, as they work together to stop the villains and save the day.

Overall, Agent 99 is an important character in "Get Smart," providing both a strong female lead and a foil to Smart's comedic persona. Anne Hathaway's performance as Agent 99 was well-received by critics and audiences, and helped establish her as a versatile actress in Hollywood.
