Whyman (ホワイマン Howaiman) is the name Ryusui gives to the source of powerful radio wave messages the Kingdom of Science receives after the creation of the antennae. The name is chosen as the messages consist only of the word "why" in Morse code.[1]

Whyman is the main antagonist of Dr. Stone.


The face and gender of the Whyman is unknown, but is normally shown in the manga as an extremely gaunt, skull-like face with hollow eye sockets and no nose. They've also got two layers of teeth, with the outer/top layer looking similar to a child's teeth x-ray.


The true nature and motives of the Whyman are currently unknown. However, their main goal seems to be to keep humanity petrified, as both with Treasure Island later on the Perseus, the Whyman attempted to petrify everyone using the petrification device.


Age of Exploration Arc

The Whyman is first heard communicating with the Kingdom of Science using Morse code on the motorboat, soon after the "crazy-strong" radio tower is turned on for the first time. The message that saturated the radio frequency the Kingdom was using consisted of one word being repeated over and over: "Why?".[2]

This call shocks the members on the boat, with Senku responding via their radio by calling them out as the source of the petrification. The signal immediately stops, leaving the group to speculate on who or what the signal came from. The group chose to assume the Whyman is an enemy, as the worst that can happen is they over-prepare for someone who is in fact an ally.[3]

Determining the nature of the Whyman is a major goal of the Source of the Petrification Saga.

Treasure Island Arc

During the voyage to Treasure Island, Soyuz comes forward as a previous inhabitant of the island. Chrome speculates that the Whyman may be a member of the Treasure Island, as there can't be many other living humans in existence thanks to the petrification.[4]

After the conflict on Treasure Island is done and the cellphone is fixed, Ruri tells the team that they've been receiving a strange message. Their connection is then cut off by a second strong signal that takes over the radio waves in an attempt to activate the petrification device remotely, with the stated distance being Earth's diameter (12,800,000 metres) and the time as 1 second. This call has the Kingdom of Science confirm that the Whyman wants to see all of humanity petrified. However, the voice, as noted by Ukyo, is a synthetic voice matching Senku's.[5]

New America City Arc

The source of the Whyman's transmissions is apparently on the Moon.[6]

The Kingdom of Science decides to travel the world and gather supplies for space travel to confront the Whyman. Some members want answers while others, like Matsukaze, want revenge.[7]

South America Arc

Dr. Xeno reveals that he is also aware of the Whyman and the signal coming from the moon, which surprises everyone. Despite their enmity, he proposes an alliance to defeat Whyman with Senku who gets excited as Xeno hopes that they can work together to figure out the source of the Petrification and they proceed to exchange information.[8]

Following the Fall of the Science Kingdom personnel stationed at San Francisco, Joel exploits Whyman's regular interval radio to petrify everyone, including Senku, by using his modified watch that also serves as radio transmitter.
