What is Sanji’s life experience?

The prince is also an artificial human being.

He is the third son of the Vinsmoke family. His father, Gaji, is the king of Germa 66. Chapter 840 of the One Piece manga proves that Sanji is not a human, but an artificial human.

Gaji was originally a colleague of Vegapunk, an outstanding scientist, and they engaged in scientific research together. Later, Vegapunk was captured by the World Government and imprisoned, so Gaji began to research artificial humans on his own. Technology, completed research on replicating and transforming life, and created 5 children.

Except for Sanji, the other dead people have abilities far beyond ordinary people. Sanji has an ordinary body, so Gaji puts Sanji in a dungeon and lets him fend for himself. Extended information

Sanji's childhood

Although Sanji looked no different from his other brothers when he was a child, there was a huge difference in physique. He couldn't keep up with his father's rigorous training and was often bullied and teased by his other brothers.

Kaji asked researcher Sanji about his situation, and the researcher said that compared to other brothers, Sanji was a "failure" and just an ordinary person. This conclusion also made Kaji consider giving up Sanji.

Although Sanji's sister makes fun of Sanji in front of everyone, she still cares about her brother very much in private. Because she knew that if she didn't smile, she would be bullied.

At this time, Kaji finally made up his mind to obliterate Sanji's existence. The young Sanji was put on an iron mask and thrown into the dungeon to die: leaving Sanji alone in a dark cell deep underground. Here, the soldiers left.
