Marco Oshiro

Marco Oshiro (マルコ Maruko) is a professional Ranked player of the Ink Sports League and a major anti-hero of the Inkling Ascension AU series. He is the older brother of Lucas Oshiro and Annie Oshiro. Though he works almost exclusively alone, he aided the New Squidbeak Splatoon temporarily during Great Turf War II.

Marco came from the Calamari County, living in unknown rural area. He moved to Inkopolis at age 14 to pursue the Turf War sports and has excelled since. As he is typically a "lone wolf", Marco has never been part of a registered team. He specializes in numerous classes of weapons with no favored class, but mains the N-ZAP '89. He also owns a katana and is well-trained with it. This makes Marco unique from other characters of Inkling Uprising in this regard, as he is the only character to officially wield and specialize in a non-ink-based weapon.

Despite numerous attempts to discover it, Marco's true intentions and motivation are unknown. Very little is known about Marco's childhood beyond his birthplace, but it is hinted he may have some history with Hera Braun, as the two recognized each other during their first encounter.
