Radio Wave is not known for precision. Today he accidentally teleports into the castle, and in a split second decision transforms into a royal guard. Neither is he known for good things happening to him, on that same day all four princesses were to make an appearance, Shining Armor and Flash are in need of advice, and a mysterious being is thought to be plaguing the castle. Fortunately Radio Wave is known for overcoming impossible situations.
