CDR Mike "Viper" Metcalf is an instructor at TOPGUN & a old friend of Maverick's father "Duke Mitchell". A Vietnam war vet who flew a McDonnell Douglas F-4 Phantom II along side Duke. When he first meets Maverick he is not impressed about him being below the hard deck nor him buzzing the tower which got Air Boss Johnson upset. He is impressed with his skills even after he broke away from Hollywood in training. He even visits Maverick in the hospital after Goose's death & tells him the story about how many pilots were lost during the war. One day as Maverick pays a visit to Viper's house he tells him about knowing his father & the truth about what really happened to him despite the information about the incident being classified. He also tells him that he has earned enough points to graduate or that he could quit. At the graduation he tells Maverick, Iceman, Slider, Hollywood, & Wolfman that they are needed aboard the Enterprise. He also tells Maverick that he would get his R.I.O. when he got there and in case he didn't he tells him to that he would fly with him if needed.
