Mars

マーズ

Mars made her debut in Losing Its Lustrous!. Together with Saturn, she tried to steal the Lustrous Orb from the Celestic Town museum. She also appeared in Double Team Turnover!, where she told Cyrus that the Red Chain project was nearing completion.
Mars appeared again in Steeling Peace of Mind! alongside her Purugly. She brought the Spear Key to Iron Island, where she activated the ruins to pinpoint the exact location of the Spear Pillar on Mt. Coronet. After failing to complete the task in Saving the World From Ruins!, she attempted to blow up the island on Cyrus's orders, but failed because of Riley and his Lucario.
She later appeared in The Needs of the Three! and The Battle Finale of Legend!. Following Cyrus's disappearance, she became distraught and even tried to follow him, but Saturn stopped her. The pair, along with Jupiter, were later arrested.
