Ace, Sabo, Luffy(ASL Brothers)

As a child, Ace is shown to have often worn t-shirts with two-kanji phrases on the front (such as "innocence" and "violence"). On some occasions they are linked to the scene in which they were worn, like "independence" when the three brothers built their own tree house to live in. He often wore knee-length shorts and a black elbow guard on his left arm. Ace was always seen wearing dark brown, flat, slipper-like shoes, and in the winter, he wore a green cardigan over his normal clothes. At age 7, Luffy accidentally ate the Gomu Gomu no Mi, which turned his body into rubber. Shanks also gave Luffy the very straw hat that has become Luffy's signature accessory, having gifted it to the boy as part of a promise for them to meet again someday after he became a great pirate.[35] Growing up on Dawn Island under the care of Curly Dadan, Luffy befriended and became sworn brothers of the late "Fire Fist" Portgas D. Ace and Revolutionary Chief-of-Staff Sabo. Sabo was a ten-year-old boy at the time of Luffy's flashback, the same age as Ace at that time. He had round eyes, a missing tooth, and short curly blond hair. He wore a large black top hat with a pair of blue goggles wrapped around it, a blue jacket with the sleeves rolled up, a cravat and a pair of light blue cyan shorts held up by a belt with an elaborate flower-design buckle.

Before he entered into the Gray Terminal, he was seen with a gentle outfit with a white colored short-sleeved shirt and wearing blue colored shorts as usual.

Curly Dadan is a friend of Monkey D. Garp and the foster mother of Portgas D. Ace and Monkey D. Luffy. Garp entrusted her to take care of Ace shortly after the boy's birth. Later, Garp also left Luffy in Dadan's care. She took care of Sabo too when he moved in.

Dadan lives on Mt. Colubo near Foosha Village. She is the mountain bandit boss of the Dadan Family and a wanted criminal. Garp also threatens her freedom if she doesn't take care of the kids he brings
