Marty is a zebra which lived and was zoo borned at the Central Park Zoo, and a good friend of Alex. at a young age, he did not trusted Alex, but years later in adult form he befriended Alex, and the two were insepratable. In the beginning, Marty lived a life of comfort in the zoo, but comfort led to boredom and Marty soon saw that his tenth birthday came and went and with that, his life was halfway in. Marty decided, then, that he must travel to the wild, for at least a short time, never having seen the wild. At one point in the movie, Alex says he's black with white stripes, as he has 30 black, and only 29 white, but this was partly due to the fact that Alex had to give an explanation as to why he was licking Marty, as he thought he was the steak in his dream. their friendship was challaged alot at times, via being lost in Madagascar, saving it from a demonic cobra lord and his followers, and facing Alex's dark side, but was congured by a life long friendship (having a wise crecking female Hynia destroying Cobra's meddailian helps too)
Marty joins the shell louge squad cause he appeartly still has a taste for adventure. he is like a more adventureious brother to the louge.
