Canon
Mikey and Donnie are one of the closest pairs among the brothers, often being teamed up for missions.

Season 1
REPO MANTIS

Donnie is having Mikey help him at the junkyard, easily distracted by everything he finds. Mikey however sees a car about to drop on them and tries to get Donnie's attention, before he is forced to pull him away. The car drops and Donnie says he would have appreciated a heads up next time. Mikey is annoyed but points out when he sees a replica of a car from their favorite sci-fi series "Jupiter Jim". Donnie decides that they need it, but Mikey asks how they're supposed to get it without talking to humans. They're then met by Repo Mantis, the guy who owns the place and is actually a mutant. Mikey starts to beg for the car, but Donnie pulls him aside. He tells him that this is a negotiation and they need to play it smooth. Repo offers to the car for them in exchange for them doing a job. Mikey wants to take it, but Donnie decides they need a sidebar. He tells Mikey that Repo Men need to be mean, and Mikey's kind of a softie. Mikey says that hurts his feelings, which makes him see Donnie point, but Mikey insists that he can do this.

They take the job and head into the woods, where Donnie explains everything he learned on the guy while Mikey grips onto his arm. They reach where the RV is and see the guy walk out cloaked in shadow, the two immediately getting scared. Donnie suggests they call Raph and Leo, but Mikey stops him. He reminds him of the moon buggy, and Donnie says if they do this they have to be stealthy. The guy ends up behind them and they freak out, but he reveals himself to be a friendly mutant who owns a puppy rescue named Todd.

Upon realizing that Todd is the nicest guy in the world, Donnie pulls Mikey for another sidebar. Donnie insists that they're going to need to be touch and Mikey forces himself to agree. Mikey tries to be touch, but is continually distracted by the puppies, and end up getting roped into helping out. Mikey asks why they just did that, and Donnie has no idea. They then end up feeling guilty about having to take the RV and leave the puppies in the cold, and end up building Todd a new sanctuary.

They take the RV back, but Repo ends up negging on their deal, and they have to fight him. They then hop in the buggy and excitedly find that it works, racing off. Donnie comments on how slow it is, and Mikey points out that it was made for the gravity of the moon. Repo chases after them, and Mikey tries to unleash the weapons but nothing happens. Donnie points out that it's a movie vehicle and nothing is gonna happen, but Mikey says that if it's from a very specific film it might. He then finds the hidden compartment and sees that it has a turbo boost and other functions. Donnie still can't shake him, and Mikey unleashes an oil spill, but it doesn't help much. Mikey thinks to try the bug zapper, and Donnie asks why he didn't think of that first. Mikey says that it didn't have a 3000 after it and Donnie writes one after the name. He asks if Mikey is happy, and Mikey is, pressing the button and throwing off Repo. They then high five and drive off back to the lair.

Fanon
Like all relationships between the turtles, TMNT fans love Donnie and Mikey's dynamic. While it may vary slightly from media to media, Donnie and Mikey are often two of the closer turtles. As typically while Raph and Leo are fighting the two will have a sub-plot together, where they're just getting along and not fighting.

2003 fans often appreciate how much of a big brother Donnie is to Mikey. Specifically whenever he goes out of the way to make Mikey feel better, or does something that would inconvenience him for Mikey.

The alternate name "B Team" comes from the 2012 series, where Leo and Raph referred to the two as the B Team.

Rise fans often note how Mikey is the only turtle Donnie allows to show him physical affection. As Donnie is often adverse to affections from his other brothers, but is okay whenever Mikey gives him hugs.

On AO3, the gen version of MikeyDonnie is the second most written ship for Mikey and the third most written for Donnie. It is also the fifth most written ship in the Teenage Mutant Ninja Turtles - All Media Types tag.
