The King of EX Panda governs his planet and confronts a crisis when the Heart Plasma—a vital energy source that once spread universal happiness—is shattered by an unknown hostile force. This destruction directly endangers EX Panda's peace and stability. In response, the King dispatches his son, Prince Go Expanda, as the planet's representative on a critical mission to Earth, tasking him with recovering the scattered fragments. This decision initiates the primary narrative, positioning the Prince's journey as essential for restoring balance to their homeworld. The King's background establishes him as an authority figure invested in interstellar welfare, though specific details about his physical appearance, personality, or governance beyond this crisis remain undocumented across available sources. The character functions solely as the initiator of the central quest, without appearing in subsequent events or expanded media narratives.
