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.

Your power, your life...I am taking them all.

Monster Association Arc
After Homeless Emperor's defeat, it appears in his mind. It then expresses its frustration at Homeless Emperor and takes away his power and his life.

Abilities & Powers
Not much is known about the full extent of its abilities, but it can be assumed that it is possibly one of the most powerful characters in the entire series, due to its ability to bestow powers to individuals.

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 also capable of taking back the granted powers along with the life of the wielders. It is unknown if there is a limit to how many people it can give powers to at once.

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

Trivia

 * Due to its enigmatic appearance and ability to turn an ordinary person into a Dragon level monster, many people assume it's the God level threat from Shibabawa's prophecy, but this has yet to be confirmed.
