Polymice

Polymice is the poly ship between Mickey Mouse, Minnie Mouse, and Mortimer Mouse from the Mickey Mouse and Friends fandom.

Canon
Mickey and Minnie are usually dating in most media featuring both characters. Meanwhile, Minnie and Mortimer are stated to be exes. When exactly this would have taken place is generally not clear as Mickey and Minnie are usually depicted as having been together since middle school or high school. Though Minnie usually prefers Mickey's company, she is shown to still have an amiable relationship with Mortimer in his introduction. While in some more recent cartoons featuring the two interacting will depict Minnie as not particularly fond of Mortimer, some Topolino comics show the two as still being friends and may hang out with each other when Mickey is not around. Mortimer is Mickey's rival for Minnie's affections, even though she usually prefers Mickey over Mortimer in most appearances. Usually, this dynamic will be portrayed as vitriolic in nature with the two at odds with each other such as in Mickey Mouse Works.

Mortimer made his first appearance in animation in the 1936 short film Mickey's Rival. Mortimer is presented as Minnie's old friend, and he arrives in the middle of Mickey and Minnie sharing a picnic together. Minnie seems glad to see him, but Mickey is immediately jealous. Minnie introduces Mortimer as an "absolute dream", then Mortimer introduces himself to Mickey by means of a prank. Despite Mickey's feelings towards Mortimer, he joins the couple on their picnic. Mortimer spots a bull in a nearby pen, and offers to fight it for Minnie. She watches on excitedly, telling Mickey about just how good Mortimer is. Mickey storms off in a jealous huff. When the bull tries to charge through the gate in the fence, Mortimer panics and runs off. Mickey, realizing that Minnie is in danger from the wild animal, comes to her rescue. He saves her and they ride off together in Mickey's car, their relationship reconciled.

In House of Mouse, their rivalry is portrayed as being more one-sided, with Mortimer eager to one-up an apathetic Mickey. He is constantly vying for the affection of not only Minnie, but Daisy Duck as well. In one episode, Mortimer pretends to be a restaurant critic so that the employees of the club will wait on him. He demands that Minnie and Daisy sit with him in his booth, but they both eventually run away in disgust. In another episode, Mortimer tries to break Mickey and Minnie apart by spreading rumours that they are each on the look out for a new partner.

In the 2013 Mickey Mouse cartoons, Mortimer appears again as Mickey's rival for Minnie's affection. He approaches Mickey and asks if he can take Minnie out on a date. Mickey, who is unable to say "no" to any request cannot refuse. Minnie, however, can refuse, and stomps on Mortimer's foot. Mortimer is seen latter with a foot injury, and he tells Mickey that Minnie isn't worth the stress.

In some media, such as Mickey Mouse Clubhouse or Mickey Mouse Funhouse, Mickey and Mortimer are good friends. In the latter show, Minnie is shown to be concerned by their friendship. As Mickey is far too eager to impress Mortimer, she finds Mortimer to be a bad influence on Mickey.

Fanon
Most work depicting the three as a polycule features all three mice dating each other. However, some feel that Minnie and Mortimer are not likely to get back together, instead seeing the two of them as both dating Mickey but not dating each other.

Polymice is considered a rarepair in the fandom, as most fans tend to either ship MickMinn or MortiMick. There are very few fan works that revolve around MortiMinn.
