Mark aka Marshmallow Markey

As the younger brother of "Johnny Marshmallow," young Markey has a lot to live up to. On the one hand, there are expectations that he is the town's next great athlete. On the other hand, he's the only brother of the town's most beloved fallen hero. Driven to clear his brother's name, he has now secretly joined the struggle against the Marshans, where Professor Fluffernutter feels his highly developed skateboarding skills, confidence, and the chip on his shoulder will be great weapons against the Marshans. Together, Mark, Seymour, and Kristina make up The M-Force, defenders of Marshmallowville, who use the inventions of Professor Fluffernutter against the dreaded Marshans. Though not the oldest, he is looked to by other members of M-Force as the leader. He is fearless to a fault, often acting before he thinks his actions through, which sometimes puts him, and M-Force, in some rather compromising positions. Only eight years old, he lives by the motto "Play Hard. Eat Soft."
