Mikhailo Aleksandr Milkovich ‘Mickey’ Milkovich is the often serious and violent older brother of Mandy Milkovich and son of Terry Milkovich. He is known as one of the most aggressive neighborhood thugs; having stolen several items from stores, being sent to juvie at an early age, and having several weapons in his household.
He was first introduced on the show as a greasy thug who terrorized Ian because Mandy accused Ian of assaulting her. Mickey was closet gay and he and Ian start a relationship. At the start, it seems that Ian is the boy most affected by their relationship. Eventually, there were signs that he cared more about Ian than he was willing to let on.
But at the end of Season 4, after having been raped by a Russian prostitute (Svetlana Milkovich), he comes out in front of a crowd where Yevgeny’s baptism after-party is being held. Subsequently, Mickey allowed Ian to live in the Milkovich home before Ian broke up with him. He is seen to have a developing relationship with Fiona and Lip.
Mickey is still betrothed to Svetlana and is the presumed father of Yevgeny, in which he has agreed to take care of. Struggling with Ian’s spontaneous behavioral problems, Mickey is seen to slowly come to terms with the effect that bipolar disorder has on Ian, and realizes that he needs medical attention.
After escaping prison at the end of season 7, Mickey went across the Mexico border alone.
