Senku, a slim and average-height young man, stands out with his spiked white brush-like hair and sharp red eyes. Two locks of hair drape over his face, adding to his distinct appearance. His stone markings, two symmetrical diagonal lines above his inner eyebrows, serve as reminders of his petrification. However, after being revived in the rocket, Senku's petrification scars have fully healed, allowing him to continue his scientific endeavors without physical reminders of the past.
