One of the top warriors on Nonpareil, StarFire is known not only for his loyalty to the Diamond Princess and Dark Jewel in protecting The Diamond Kingdom of Nonpareil, but is commonly referred to as the "mute warrior" as he hasn't spoken a word since stepping foot on the planet. No one knows why, nor asks questions, considering he is one of the fiercest warriors The Diamond Kingdom has seen.

Some rumors around The Seven Planets of Zero state StarFire's strange suit symbols and patterns date back to ancient hieroglyphics, but they have yet to reveal the true origin.
