First appearing in Dr. Stone Chapter 95 and Episode 38, Why-man is introduced as a cryptic being that transmits a single repeated word – “Why?” – via Morse code. This eerie presence picked up shortly after the Kingdom of Science activated a powerful radio tower, which is soon suspected to be the source of the global petrification event.

With no clear origin and visual form at the time, Why-man becomes the focus of intense speculation as Senku and his allies try to determine whether this unknown entity is a friend or foe. Keep reading to find out everything you need to know about the enigmatic figure, but keep in mind that there are spoilers ahead.

Originally, Why-man’s unsettling image – a gaunt, skull-like face – served only as a symbolic representation rather than its true form. The reality, however, is even more extraordinary: Why-man is not a person in Dr. Stone but a collective consciousness of alien devices known as Medusa.

These artificial, sentient machines travel across space in search of intelligent life capable of understanding and reproducing them. Their goal is survival and reproduction through parasitic cooperation with advanced species.

The Medusa units mistakenly concluded that humanity lacked sufficient intelligence based on the species' delayed recovery after global petrification in Dr. Stone. Why-man remained on the Moon for thousands of years, perplexed by the lack of response and unsure whether humans rejected the “gift” of eternal life.

Eventually, it began sending messages and even attempted to assist humanity using petrification devices, but its efforts were often misunderstood or rejected. Why-man's aggressive actions, including repeated attempts to petrify Earth, confirmed it as a dangerous adversary.

Yet, as the story progresses, the Kingdom of Science discovers Why-man's true nature and intentions. While most devices choose to abandon Earth and seek new hosts elsewhere, one Medusa, driven by curiosity and a willingness to coexist, stays behind.

This device, retaining the Why-man title, becomes a bridge between humanity and its extraterrestrial creators. By the end of Dr. Stone, Why-man's identity transforms from a cryptic threat into a mirror of human progress, echoing the series' core theme – science as both a survival tool and a path to mutual understanding.
