Swordlord P: Peanut Otter's alter ego. He is a sword-wielding child wearing a cowboy hat, a black belt, and a star badge. He battles opponents with his trusty sword. He can also throw katanas and chakrams.
G.I. Jelly: Jelly Otter's alter ego. She is dressed in a hi-tech armor suit that protects her body (except for her head) from strong blows along with a ninja headband. She fires a variety of projectiles from her rather bulky arm cannon.
Kick-Butter: Baby Butter's alter ego. She wears a red hair-bow (which gives her more stamina and distinguishes her from male characters), grey boxing gloves, and a black belt just like her brother Peanut. She can use a variety of boxing moves and generally relies on unarmed combat, making her tougher than her normal ego. She still speaks in only simple words and sometimes phrases.
