God

God is an enigmatic entity who appears before Homeless Emperor.

Appearance
In its first appearance, it looked like a swirling gust of wind with flesh floating along with it. When it made its second appearance, it looked like a giant humanoid figure made entirely of flesh and bones with no face. It is unknown whether its physical form is the same, or they 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, only with its appearance being changed into a colossal giant of flesh and fractured bones. 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 communicated with him. It was also able to freely change the appearance of its projection in Homeless Emperor's mind.
