[3] Max is one of the few Disney characters, aside from his best friend PJ and Huey, Dewey, and Louie, child or otherwise, who has actually aged in subsequent appearances.

While Goofy is still clumsy, he works hard to be a good father towards Max, at one time reprimanding him to take personal responsibility by telling him about his (Max's) great-uncle, Eliot Goof, an FBI agent with a never-give-up attitude (and a parody of Eliot Ness).

The Goof Troop series shows some of his relatives – an older cousin named Debbie was featured in the episode "Leader of the Pack".

In one episode of Goof Troop, Goofy says that Max was scared of the witch in Snow White and the Seven Dwarfs when he was younger.

[11][12] Max, like in all of his appearances, loves his father but wishes he would be a bit more normal, and dislikes the idea of sharing similarities with him.

In this movie, Max has grown to find his father's goofy antics embarrassing, and is likewise viewed by his peers as a geek and a goof himself; a view he seeks to change at the school assembly when he dresses up like the musician rock star Powerline and interrupts the principal's speech to dance and perform to Powerline's hit song "Stand Out" before the entire student body.

Though Max ends up in detention for hijacking the assembly, he succeeds in not only impressing the other students but also winning the affections of Roxanne, who shyly yet delightedly agrees to go with him to a party that is to be held the next Saturday.

By the end of the film, when the two arrive back home, Max reveals to Roxanne that he lied, admitting that he just wanted her to like him.

and Bobby to join them, Max makes a bet against the Gammas' leader, Bradley Uppercrust III, to see who will be towel boy to the other should either win the X-Games.

He attends the same college as his son, much to Max's dismay as he had hoped to finally get away from his father's overbearing doting.

When Goofy inadvertently beats Max at the qualifying rounds for the College X-Games (thanks in part to some sneaky cheating by Bradley), Max ends up blowing up at his father, revealing his desires to get away from his father and estranges him completely by telling him to "leave him alone and get his own life", sending Goofy into depression.

During the final stretch of the triathlon, Bradley activates a rocket hidden in Max's skateboard, causing an explosion that ends up trapping fellow Gamma member Tank underneath some fallen fiery debris.

The two part ways amicably, with Goofy - now cured of his empty nest syndrome - leaves Max to live his own life at college and heads on another date with Sylvia.

While all the main Disney cast (Mickey, Minnie, Donald and Daisy) attempted to keep Goofy away from the two so as to not embarrass Max in front of Roxanne, they ended up embarrassing him themselves until Goofy finally cuts in to give Max and Roxanne some privacy for the night.

However, after staying up all night with no luck, Goofy is filled with disappointment, leaving it to Max to cheer his father.

He brings his lady friend Mona (whom Max hopes to make his girlfriend) home for Christmas to meet his father.

In the end, as Mona finds Goofy's quirks to be endearing, Max decides to forget his embarrassment and join in the fun.

During the end credits sequence, a pop-up book version of Max and Mona are seen sliding close to each other (presumably to share a kiss) before a pop-up version of Goofy covers them both from view with a picture frame containing credits specific to the "Christmas Maximus" segment.

[14] In the 2022 film Chip 'n Dale: Rescue Rangers, he makes a cameo appearance in his original Goof Troop look during the credits scene.

In a promotional video in honor of Disney Channel's fortieth anniversary, a chibi version of Max appears on his skateboard swiping and drinking the milk bucket from the Greens before throwing it into the cake mix.
