God

The following section contains Webcomic spoilers. You have been warned manga-only readers.

An enigmatic entity referred to as "God" by Homeless Emperor.

Appearance
In its first appearance, it looked like a swirling gust of wind with flesh floating along with it. With its second appearance, it looked like a giant humanoid figure made entirely of flesh and bones with no face. It is unknown, if its physical form is the same, as those were just imaginary projections in Homeless Emperor's mind.

Personality
It appears to be extremely evil, wanting the eradication of all humanity. It also seems to dislike failures, as it mercilessly killed Homeless Emperor after his defeat.

Supernatural Abilities
Power Bestowal: The enigmatic entity is capable of granting supernatural powers to individuals. It gave Homeless Emperor the incredible power of summoning energy spheres similar to little suns which explode at the first contact and create huge and flaming bursts. It is possible that it is also behind Garou's "monster transformations" and increase in power, as Garou showed up just after Homeless Emperor's death, and Saitama noticed "something in the wind" as Garou increased in power and changed his form. It is also capable of taking back the granted powers along with the life of the wielders.

Telepathy: It was able to get inside Homeless Emperor's mind and telepathically communicated with him. It was also able to freely change the appearance of its projection in Homeless Emperor's mind.
