Mag

Mag is a young giant boy with short, pale hair that sticks up from his crown. Even among his Walrus School classmates he is unusually huge, dwarfing the other children. He goes shirtless beneath a fur cloak and keeps a pair of goggles on.

In keeping with his school's teachings, Mag rejects both violence and coarse language. He has no enthusiasm for studying and deliberately skips his homework, yet he is sure of his own physical strength. His one true terror is Loki, and he carries a streak of superstition, taking his abduction as karmic payback for some past misdeed.

When the Straw Hat Pirates stopped by the Walrus School, Mag explained to Luffy, Zoro, and Usopp that rough talk and warrior training were no longer permitted there. He and his classmates were annoyed when Colon later turned up and picked a fight with Luffy, and after the crew departed Mag sat in Ange's class, drawing Loki when asked to depict his greatest fear.

Mag and eight other pupils were then seized as hostages so the Knights of God could pressure Elbaph's adult giants into a coming war. Put to sleep and drawn along by controlling arrows, the children were marched through the forest, spared from a fire only by Jinbe's intervention. Once awake they found themselves unable to move under Gunko's arrow control, and a burst of Imu's Supreme King Haki knocked them out again. As they were herded toward the coast for shipment to Mary Geoise, their guardians arrived to help, and a clash with a Nika MMA ended with a stray blow capsizing the waiting ship.

The damage tore open a hole down to Elbaph's Underworld, and with Gunko no longer in control her arrow forced the children toward a fatal drop. Rather than let them fall alone, each guardian embraced their child through the thorns and plunged with them, landing safely on Loki's back below. In the Western Village the children bravely stood between the sadistic Sommers and their guardians until Zoro, Luffy, and Loki put him down and the binding thorns fell away. Even so, Killingham later summoned a flood, recaptured the children, and readied them once more for extraction.
