Background / History

Saint Marcus Mars is one of the Five Elders and the Warrior God of Environment. He answers directly to Saint Nerona Imu alongside Saint Jaygarcia Saturn, Saint Topman Warcury, Saint Shepherd Ju Peter, and Saint Ethanbaron V. Nusjuro 2.

When Saint Germain Sumer revealed his knowledge of the world's future, Mars initially regarded him with suspicion and contempt. Sumer's awareness of Mars's Itsumade transformation particularly unsettled him 3 11. Imu later assigned Mars to verify Sumer's claims by retrieving Monkey D. Luffy, Golden City Shandora, and the Poseidon Poneglyph from Sky Island; Sumer was permitted to accompany him 5.

Mars flew Sumer from Mary Geoise to Mock Town and Sky Island in his full beast form. Though cold and impatient, he advised Sumer to master the powers Imu had already granted him rather than pursue Armament Haki with an ordinary physique 7 8. Upon reaching Sky Island, Imu possessed Mars's body to investigate Shandora and confront Enel 8 9.

After regaining control, Mars was deeply shaken by the confirmation that he and the other rulers may be manga characters. He nevertheless acted immediately, ordering the Navy to seize Sky Island and deploying a Buster Call against Jaya Island 11. The resulting bombardment destroyed Jaya and killed its inhabitants 16 17.

Appearance

In human form, Mars is a tall, thin man with a goat-like beard. He typically wears a black suit beneath a blue coat 3 7.

• Thin, imposing facial features and a goat-like beard 3 24
• Usually dresses in a black suit with a blue coat 7
• His full beast form resembles the legendary Itsumade: a huge monstrous bird with a fanged, spiked head, brightly colored wings, sharp talons, a serpentine body, and black flames 6 7
• His avian form grants bird-of-prey vision capable of seeing details far beyond Sumer's sight 8

Personality

Mars is authoritative, proud, and intensely loyal to Imu. He treats orders as absolute priorities, refusing to delay the Sky Island mission even when Sumer asks for rest or food 8. His status as a Five Elder has made him accustomed to command; he expects immediate compliance from the Navy and dismisses objections to his demands 11 17.

He can be unexpectedly patient when dealing with Sumer, offering practical advice about Haki training and protecting him from human traffickers with Conqueror's Haki 7. However, he is also dismissive of Sumer's strategic warnings, particularly concerning Luffy and the possible consequences of altering the original plot 13 32.

Mars displays extreme indifference toward civilian lives. He ordered Jaya Island's destruction and later commanded the execution of the Franky Family and their relatives, only accepting Franky's reprieve because Sumer intervened 16 43. When Sumer was abducted by Dragon, Mars became visibly anxious, fearing both Sumer's importance to Imu and the consequences of his own failure 47 48.
