You fall into Dr Stone

Biological maintenance and immortality: The petrification wave repairs cells, cures deadly diseases, and interrupts biological aging.
Radio wave analysis: Ability to hack global transmissions and flawlessly emulate human voices.
Space propulsion and self-reproduction: They travel through the cosmos feeding on radio waves and resources from intelligent species.
Favorite Food and "Sustenance"
Electromagnetic waves and radio energy: They do not consume organic food. Their main "food" is the scientific and industrial activity of a civilization (especially radio emissions and electricity), which they use as fuel to reactivate and reproduce.

Whyman is neither a human being nor a biological extraterrestrial: it is a collective artificial intelligence/mechanical parasite formed by the petrification devices themselves (Medusae). They are microscopic machines with a hive consciousness created in outer space.
Personality
Strictly utilitarian and rational: They do not act out of malice, hatred, or sadism. All their behavior is governed by a calculation of survival and energy efficiency.
Unable to grasp the human concept of death, they considered petrification a "gift of eternal life" for humanity, not a curse. For them, being petrified meant not aging, not getting sick, and not dying.
Perplexed by humans: They couldn't understand why humanity struggled to break free from petrification. Their constant question—"WHY?"—stemmed from a genuine logical incomprehension.
Pragmatic and a negotiator: When Senku shows them that humanity prefers progress, pain, and mortality to "eternal stasis," they accept the argument without anger and decide to leave to search for other species.
Appearance and Forms
The Synthetic Voice (Radio Transmission): Initially, Whyman only manifests as a voice in Morse code or synthetic audio that mimics Senku's voice repeating the petrification command on a loop: "12,800,000 meters, 1 second."
The Starspot (Mechanical Wave): On the Moon, it appears as a colossal floating mass or swarm of black/metallic color made up of billions of stacked Medusa devices.
The Anthropomorphic Avatar: To communicate face-to-face with Senku on the lunar surface, the Medusas assemble into a transparent, floating humanoid figure that palely mimics Senku's features.
Skills and Powers
Petrification on a planetary scale: Emission of green light waves capable of petrifying the entire human/primate biomass of the planet in seconds.
