Black Leg Sanji

This verse is a mix of the anime and live-action and follows the canonic timeline pre and post-time skip.

This is an AU verse in which Sanji never escaped his family. Instead of fully giving up on his 3rd son, Judge put him through additional experimentation and harder training until his body's latent abilities were forced to awaken.

Since he knew what it was like to have emotions, even as he began to lose his ability to feel them, he tried his best to maintain whatever he could. Knowing that his emotions were what his mother had tried to protect by drinking the poison in the first place. This caused them to not fully be erased but muted and suppressed. A fact that he hides from his family after the years of abuse that having them brought to him.
