You know what I just thought of? Not only does mikey not have human (or mutant) buddy of his own but he doesn't have a female to crush on/have a connection with eighther. Don has April who he crushes on and shares his techno geek love with. Leo has the angsty dynamic of respect/distrust with Karia since they where both honorable. And Raph has Joi that fighter gal from season five. It may have been slight but they where paired off with each other and hung out and it appeared that Raph had a thing for her. But not Mikey
I wonder if Mikey's lack of personal relationships are due to time constrainst to get a story told or if the creators just don't feel his character would fit having such heavy relationship dynamics because he is supposed to be the funny kiddy character, and instead gave his brothers those deep personal relationships.
