Fuzzy Force is a band of fuzzy superheroes who fight for freedom and justice.  Super Pup is the team's leader and physical powerhouse.  Flash Rabbit is the team's medic and caretaker.  He cooks, cleans and takes personal interest in the physical and emotional well being of his teammates.  Cosmo Cat is the team's pilot and mechanic.  Though he is awful at both jobs, he somehow manages to pull through.  Cosmo considers himself second in command of the team, but if forced to make a real decision, he would defer to the wise counsel of Flash Rabbit.  Supermouse is the team's loose cannon.  He is willing to fight the battles that none of the others would, and he is quick to rally the team against any challenge.
