Miguel Diaz is the one of the main characters of the Netflix series, Cobra Kai. He is portrayed by Xolo Maridueña. Miguel is the neighbour of former karate champion Johnny Lawrence, who convinces Johnny to train him. Miguel helps him to reopen and establish a student base at Cobra Kai Dojo, though he quickly falls into the Cobra Kai mentality of "no mercy". As his attitude shifts, his relationship with Samantha LaRusso falls apart, leading to a dangerous rivalry of his own with Johnny's estranged son, Robby Keene. Their rivalry reaches a boiling point, resulting in Miguel suffering a spinal injury, after getting sent over a balcony and hitting the stairs. When he does awaken from his coma, he is ready to rebuild his life in a healthier mindset. He recruits Johnny's help once again, this time, forming a new dojo away from the merciless teachings of John Kreese. Miguel is caught in the middle of his sensei’s long-standing rivalry with Daniel LaRusso. Despite learning of the rivalry, Miguel gains some respect for and accepts the teachings of Sensei Daniel, as well as repairing his relationship with Sam. He later befriends Robby and Tory (his ex-girlfriend) and helps them and Miyagi-Fangs in exposing Silver to his students.
