Mortimer's name was originally meant for Mickey Mouse but Walt Disney's wife Lillian thought the name made Mickey seem pompous. Years later, the name would be used for a new character created to be a rival for Mickey. Mortimer only appeared in the cartoon "Mickey's Rival" and was never seen again until 2000 when Mortimer's popularity skyrocketed and landed him roles in several Mickey Mouse related material
He is said to be Minnie's ex-boyfriend and she possibly left him due to his nature. He is very arrogant and rude, the total opposite of his rival. While he claims he loves Minnie, he shows to be incredibly selfish as seen in the cartoon "Mickey's Rival" where he leaves Minnie to be attacked by a bull that he provoked. Not only that, he attempts to flirt with any female character on screen which might also indicate the reason the relationship between him and Minnie was abolished. Also, Mortimer can be rather sexist as seen in "Mickey's Rival Returns" where he feels that Minnie is only a prize to be won. It is unkown what he does but as well as being arrogant and sexist he acan also be rather annoying.
Mortimer is essentially a taller version of Mickey Mouse, and seems a bit more human-like. Unlike his rival, Mortimer has whiskers, perhaps referencing how he has a ratlike persona. He has feet the size of Goofy's. Unlike most of the other mouse characters, however, you can see two large teeth close together, like a rat. He is usually wearing jeans and a shirt, but sometimes he also wears a hat.
Mickey's Once A Upon a Christmas
Mortimer makes a brief appearance in the film Mickey's Once Upon a Christmas. Here, Mortimer is the snooty, profound and wealthy owner of Mortimer's Department Store, and he speaks with a profound tone. Minnie Mouse and Daisy Duck are notable employees of the store, and judging by Minnie's low-budget lifestyle, he does not pay well. In his scene, Minnie hopes to earn the Christmas bonus for her extra hard work, so that she may pay for a wonderful present for Mickey. However, Mortimer only gives her a fruitcake, leaving Minnie without money to buy the gift.
Mickey's Magical Christmas
In Mickey's Magical Christmas clips where Mickey went out on the street to ask what people want from Christmas was archive footage from the show but Mortimer's scenes were cut out for unknown reasons. However he is seen two times in the audience but he doesn't talk.
TV Show Appearnces
In his first appearance, Mortimer was driving by and notice Mickey and Minnie as they were having a picnic. Minnie is thrilled to see Mortimer once again. As soon as Mortimer walks up, Mickey already knows he is bad news just as Mortimer does not like Mickey at all so he attempts to humiliate Mickey and when Mickey shows Minnie how upset he is Minnie states that he is just jealous. Mortimer then tries to impress Minnie by annoying a bull that is over a fence. The plan works until the bull finds a way out. Mortimer rushes and drives away in his car and leaves Mickey to rescue Minnie who eventually remembers why she left Mortimer in the first place
Mickey Mouse Works
In this series, Mortimer is once again the main antagonist along with Pete. Here, Mortimer is Mickey's neighbor and is still competing with Mickey to win Minnie Mouse's heart. In the series, Mortimer is apparently wealthy having far more advanced technology than his rival. One of Mortimer's most villainous roles was in the cartoon Big House Mickey where he accused Mickey of robbing his house having Mickey sent to prison. Mortimer made a guest appearance in the Pluto segment; Pluto Gets the Paper.
Mortimer's first appearance in the series was the cartoon 'Mickey's Rival Returns. In this cartoon, Mortimer and Mickey compete with each other in volleyball. The winner gets to ask Minnie on a date. Originally, Mickey refused the idea being that it would be using Minnie as "some kind of trophy", but Mortimer's arrogance angers Mickey into competing. Mickey wins, but Mortimer reveals the competition prize to Minnie having her beleive Mickey thought of her as a prize. Minnie instead leaves with Mortimer but at the date, he begins to harass her for a kiss. Fortunately, she is saved by Mickey who she forgives and has a beach dinner with.
House of Mouse
In the television series House of Mouse, Mortimer gets a role as a recurring character. Mortimer appears many times as a guest and tries to trick Mickey or Minnie into breaking up. In the series pilot episode, Mortimer appears but is seen flirting with Donald Duck's girlfriend Daisy Duck instead. Mortimer proves to be hated by mostly all of the guest at the club ranging from heroes to princesses to villains despite being one himself. It is even indicated in the episode "Pete's Christmas Caper" that the cruel Pete might even have a disliking towards him.
Arguably Mortimer's most famous appearance is where he tricked Mickey and friends into believing he was the club's critic and forced everyone to treat him like a prince or he'll give them a negative review which could close the club. Mortimer is foiled when the real critic reveals himself to be Lumière from Beauty and the Beast.
Mickey Mouse Clubhouse
Mortimer's most recent appearance is in the CG animated series Mickey Mouse Clubhouse. He has a non-speaking role in Minnie's Birthday seen sitting beneath a tree, playing a guitar. In this appearance, Mortimer wears the orange shirt from Mouse Works with yellow polka dots, blue pants and yellow shoes. He was also seen sleeping and sunbathing on the ground.
Mortimer makes his only proper appearance on the series in the special "Super Adventure!" as the main antagonist. Here, he has a supervillain ego named Megamort, who plots to take control over the Clubhouse World by shrinking all the landmarks and storing them within his zeppelin lair. During some time of the plotting, Mortimer forced the humble Pete to act as his minion, ordering him to go around to proceed with his bidding. When the problem reaches Mickey and friends' attention, Ludwig Von Drake creates a machine that transforms the clubhouse gang into a team of superheroes.
Together, they head out and are able to defeat Pete. However, Pete reveals he was forced to fulfill such evil deeds, under the control of "the big boss", who threatened to shrink Pete should he refuse to follow orders. Just then, Megamort arrives and does just that, due to Pete's failure. And with Pete no longer serving him, Megamort goes ahead and wrecks havoc amongst the world himself, leading to everything, including Mickey himself being shrinked and imprisoned. Under their hero egos, Donald, Goofy, Minnie, Daisy, and Pluto travel to Megamort's zeppelin where a battle ensues.
Successfully, they retrieve the shrunken landmarks, but causes Megamort's blimp to go haywire in the process, putting Megamort in great peril. Mickey concocts a plan to successfully save the villainous Mouse, and Megamort, being eternally grateful, apologizes and redeems himself, revealing that his true name is Mortimer Mouse, and that he's the Clubhouse' newest neighbor. With his villainy in the past, Mortimer restores the peace in the Clubhouse world and is welcomed by Mickey and the gang into their circle of friends.
Strangely, Mortimer's appearance in "Minnie's Birthday" seems to have been forgotten here, as he was showcased in "Super Adventure" as the Clubhouse's new neighbor, as if Mickey and the gang had never known him prior to those events. It could be that "Superhero Adventure" chronologically takes place first, despite having been made years later.
Mickey Mouse (2013 TV Series
Mortimer returns in Paul Rudish's Mickey Mouse animated series, once again as Mickey's rival for Minnie's affections. Here, he retains his original design from Mickey's Rival, but has a white face and black button eyes like the other mouse characters. He appears in the episode "No", where Mickey's inability to say the word "no" is taken advantage of by Mortimer, who asks Mickey to borrow Minnie romantically. Though Mickey isn't able to refuse, Minnie stomps on Mortimer's foot and storms off. Later, a wounded and handicapped Mortimer angrily tells Mickey to keep his girl, believing she isn't worth the stress. In the final scene, Mortimer joins the others in asking Mickey permission to watch TV with him and Mickey responds "yes".
- Walt was originally going to name Mickey Mortimer, but his wife insisted on a new name. Mrs. Disney felt that the name was not good enough and suggested a name which was more suitable with Walt’s home in Midwestern: Mickey.
- The name itself derives from the name of Disney's former pet mouse, Mortimer.
- Mortimer only has one small cameo appearance in Mickey Mouse Clubhouse and was possibly denied a major role due to his nature. He was quiet and was seen under a tree playing the guitar.
