Martin is a one of the many minor character of LEGO Friends.
He is Mia's love interest, and he seems to return it. Martin and Mia have shown that they have feelings for each other. In "Camp Wild Hearts", Martin declines Mia's offer to go and play archery. She runs off crying, but they patch things up later. They also dance together at the Bell Fontaine Ball in "The Grateful Dud".
