Michael "Mikey" Blumberg is an overweight, mild mannered, and philosophical 10-year old. He is good at playing goalie in football due to his height and because he is really fat. He writes poetry, performs ballet, and believes in notions of peace that are often dismissed by the others. Though Mikey is known for being a "sweet-souled giant," there have been times where Mikey is revealed to have a dark side (particularly apparent when others take advantage of him or do not take him seriously).
