Harold "Happy" Hogan is Tony Stark's personal driver and friend who is now the head of security of Stark Industries. He is portrayed by Jon Favreau, who was the director of the director of the first 2 Iron Man films. IRON MAN
Harold Hogan, commonly called "Happy", is Tony Stark's personal chauffeur and bodyguard, and one of his closest friends. He often encourages Tony's excesses, as seen when he challenges his boss in a race from Stark's mansion to the airport, where James Rhodes is waiting for their arrival to take Stark in Afghanistan for the promotion of the new Stark Industries' weapons. He stays with his boss during all of his adventures, but he only acknowledges his secret identity of Iron Man during Tony's communicate to press after the incident with the Iron Monger.
IRON MAN 2 Happy Hogan is still at Tony's employment and has added to his routine duties even the assistance to his superhero identity. He's initially seen sparring with Tony inside his mansion, in a boxing ring built in one of the many rooms. During their training, Pepper introduces one of the candidates for the role of Stark's personal assistant, Natasha Rushman. Impressed by the girl's curriculum, Tony asks Natasha to spare with Happy, but the bodyguard is quite humiliated when she annihilates him with a single, quite acrobatic move. Happy accompanies Tony to Montecarlo (Monaco), where the playboy enjoys himself in racing in the Grand Prix. During the race, Whiplash attacks him, and Happy, along with Pepper, intervenes, bringing the new armor to Tony. Happy too is attacked by the villain, but, once dressed up with the armor, Iron Man saves him and Pepper by defeating Whiplash. When Whiplash's connection with Justin Hammer is revealed and Hammer Drones go on rampage during the Stark Expo, Happy follows Natasha Rushman, aka the S.H.I.E.L.D. agent Black Widow, to Hammer's base in which Whiplash is hiding, controlling the drones. Happy engages a fight with one of Hammer's guards, managing to defeat him after as long battle, only to realize that Black Widow has defeated all the others by herself in no time. Along with her, Happy manages to interfere with Whiplash' plans, even if he already fled away, and assists Iron Man and War Machine in their battle against the Russian villain.
IRON MAN 3 Happy was promoted to Head of Security at Stark Industries, but he got a lot of negative feedback (about 300% rise!!) from other staff members almost immediately after his new appointment. When Aldrich Killian came to visit Pepper, Happy suspected Eric Savin and decided to follow him to the Chinese Theatre where Eric met Jack Taggart to deliver a batch of Extremis. Hogan later bumped into Taggart causing him to drop his case. Eric overpowered Hogan but Taggart exploded from the Extremis, causing Hogan to be severely injured and hospitalized, while vaporizing 4 innocent bystanders. Hogan was able to point to a vital piece of evidence before he lapsed into unconsciousness, an act that gave Tony a valuable clue into cause of the explosion. Tony later visited Happy in hospital and told the nurse not to turn the TV off because Downton Abbey was Happy's favorite show. After seeing what had happened to Hogan, Tony decided to get revenge on The Mandarin. Hogan later woke up from the coma sometime after the defeat of Killian and the Extremist soldiers.
