Zack <\ The Promised Neverland /

Zack is a tall young man with dark skin and a scar on his face. He has short, spiky black hair and wears a bandana that covers his entire forehead. He also wears a coat that occasionally covers the lower part of his face.

Zack is athletic, excellent with weapons and at escaping, and as such, never flinches when facing death. That's why he's called the most experienced veteran among the Goldy Pond children, and he's always the one who risks his neck during hunts. He has saved Nigel and the other children countless times, demonstrating his selflessness and loyalty.

He also knows the dangers of Goldy Pond and doesn't hesitate to take on the most difficult tasks for the sake of his comrades, as demonstrated by the scene where he volunteered to take on Bayon despite the danger. He didn't want anyone else to die in his place and felt he was the only one who could handle Bayon.

He also has complete trust in Oliver, as demonstrated by the fact that he deliberately changed the plan and handled Bayon alone, while Pepe took charge of delivering the weapon to Oliver.

Zack was born in 2028 and grew up in Grand Valley, one of the Premium Farms. At some point, he was sent to Goldy Pond as a live game.

Finally, Lucas recruited him into the Goldy Pond Resistance, making him their doctor.

Nigel says he's the most experienced veteran in the Goldy Pond Resistance.
He/She is in charge of the battle squadron.
They put him in charge of the first-aid because he was always getting injured.
Zack's favorite food is hard-boiled eggs.
Besides medical care, another of Zack's specialties is windmill repair.
