Sind

Sind is a boy who was being held captive in the Biscuits Room, on Punk Hazard.

Appearance
Sind became much larger than an average boy due to the experiments done on him at Punk Hazard. His head is rather big and not very proportionate to his body. He has light colored hair, that is unkempt and goes over his ears, he also has light colored eyebrows. He wore a sleeveless shirt with shorts, until Kinemon gave all the kids jackets. His jacket was light colored, with a dark colored hood, and fur at the end of the sleeves.

Personality
When he first met the Straw Hats, he thought Franky was very cool, and sang a song about how cool he was. He was desperate to get out of the Biscuits Room.

When deprived of the drug NHC10, Sind became very aggressive, brutally punching Luffy into part of the building. Otherwise, he is a normal timid child, as he was scared of Kinemon's severed head.

Abilities and Powers
Due to the experiments, Sind has become larger and therefore stronger than average children; strong enough to send Luffy crashing into a wall with one punch.

Punk Hazard Arc
At some point, he was taken from his family after being told he was sick and would be made healthy again. He stayed with the other children in Biscuits Room on Punk Hazard until the Straw Hats broke them out. Later, he succumbed to the withdrawal symptoms of NHC10, which he and the other children were fed regularly in candy form. Eventually, Sind became very aggressive, punching Luffy through some pipes until Usopp knocked the children all out with sleeping gas, and then the Straw Hats chained the children up for their own safety.
