Max is unusual in that he is Goofy's son, as opposed to a nephew akin to Huey, Dewey, and Louie's relationship with Donald. Some Goofy cartoon's during his Everyman years depicted Goofy as being a father to a red-nosed Goofy Jr.. Many fans believe that this character served as the inspiration for Max. In the poster for cartoons with Goofy Jr., Jr. would look exactly like Max in his Goof Troop era.
One notable aspect is that Max has appreciatively aged, in a fashion, during the course of his appearances, which is uncommon among most characters in the Mickey Mouse franchise. At the time of his introduction, he was around 11 years old, but is usually presented as a teenager/young-adult in his more recent appearances.
One of Max Goof's most notable traits in the Disney franchise is that not only is he the only child in a single parent family, but that parent is a single father. This is made especially obvious by the fact that Max's best friend in Goof Troop does have a mother with a noticeable presence in the show. Max's mother is mentioned only very briefly in one episode, where it is said that she 'is up there amongst the stars'. This implies that she is dead, making Goofy a widower.
By the time of A Goofy Movie, Max is approximately 14. As a teenager, he is very embarrassed of Goofy, and his greatest fear is that he will end up being like his father. He seems to be especially ashamed of his laugh, which is exactly like Goofy's.
The film features Max's love interest, Roxanne, and his attempts to impress her. Alongside P.J. and another friend, Bobby, he is able to put on a concert in the school auditorium, meant to be a way of shedding his "Goof" image. However, he is caught by the principal. While awaiting punishment, Roxanne comes by to talk to him, and he is able to ask her to the end of school year party. When she says yes, his excited antics lead the principal to call Goofy. The angry principal gives the false impression that Max is a juvenile delinquent. The worried Goofy decides to take Max on a father-son fishing trip, forcing Max to cancel on Roxanne. In order to impress her, he lies and says that he is going to see the rock star Powerline in California, and that he will be on stage with him for the final number.
The rest of the film revolves around Goofy's attempts to bond with Max during the trip. At one point, unknown to Goofy, a distraught Max changes the route on the map to lead to California. Coincidentally, Goofy hands over navigating duties to Max. With more freedom, Goofy and Max bond, but their relationship is stunted when Goofy discovers that Max changed the map route. Their arguing leads to their car falling into a river. However two begin to make up and have a frank discussion over recent events. Max finally tells Goofy about his crush on Roxanne, and how he lied. Goofy begins to understand that Max is growing up, and admits that it happened so fast that he missed it. Goofy offers to help Max get on stage. Max shrugs off the offer, but is unable to elaborate as the car is about to head over a waterfall. Max is able to get to safety, and is able to save Goofy from death using a fishing technique that Goofy taught him, called "The Perfect Cast".
The two somehow manage to make it to California, and are able to sneak onstage with Powerline. When they return home, Max goes to Roxanne and apologizes for lying, as he just wanted her to like him. To his shock, Roxanne reveals that she had already liked him, because of his unusual laugh. Roxanne forgives Max, and offers to go out with him that night. Max already has plans to spend time with Goofy, but arranges to go out with her the following day. Max then takes the opportunity to introduce Roxanne to Goofy, who at that moment had fallen through the roof as a result of their car exploding.
In the direct-to-video sequel to A Goofy Movie, An Extremely Goofy Movie, Max, now 18, leaves for college with P.J. and Bobby Zimmeruski. Roxanne is not shown in this movie (though it is the sequel) and there is absolutely no mention of her, hinting that she and Max have either broken up or that she is at a different college and is in a long distance relationship with him. Max joins the elite X-Games champion team, the Gammas. However, because the Gammas invited Max but not his pals P.J. and Bobby, he decides to compete against the Gammas in the upcoming X games.
Meanwhile, Goofy loses his job and must go back to college and get a degree, as it's the only way to get a new job. Since Goofy is suffering from loneliness due to Max's absence, he chooses to attend the same college as his "Maxie". At one point in the movie, Max manages to distract his father with Mrs. Marpole, the librarian, while he sneaks off to practice skateboarding. When Goofy gets a date with her, he rushes off to tell Max only to interfere with Max's practice; the result is Bradley Uppercrust III, leader of The Gammas, perceiving Goofy's clumsy antics on Max's skateboard for skill and offers him membership to the Gammas.
Max encourages his father to join, viewing it as an opportunity to escape Goofy for a while. When this fails to work, Max reveals his desires to get away from his father, sending Goofy into depression. When Goofy overhears the Gammas' plan to fix the games, Goofy tries to warn his son, who doesn't believe him. Once it becomes clear the Gammas are cheating, however, Max asks his dad to fill in for the incapacitated P.J. During the final stretch of the triathlon, Bradley detonates an explosion in the X games balloon, trapping fellow Gamma member Tank underneath. With help from Goofy, Max rescues Tank and beats Bradley to the finish line. In the end, both father and son make amends by Goofy's graduation.
