Power Bestowal

You are correct; humans are foolish. But you have no need to die, I will grant you power. What to do with this power, you should know.Power Bestowal is the ability to bestow strength, new abilities and powers upon others.

Overview
The user can give new abilities, strength or superpowers to others. So far, the only characters that shown to have this ability are Monster King Orochi, but especially "God", with the latter being able to bestow superpowers upon Homeless Emperor, originally an ordinary human, giving him the ability to summon energy spheres which are capable of causing great destruction similar to that of the Dragon-level threat Vaccine Man. Homeless Emperor's newfound power from "God" also makes him become a powerful Dragon-level Mysterious Being and capable of easily dominating the S-Class hero Zombieman during their battle. "God" has also shown to grant Psykos a massive power boost during her fusion with Orochi, increasing their potency to such devastating levels that a single energy attack from the newborn fusion is able to cut through the Earth's surface, lifting the oceanic crust and creating tsunamis over a portion of the planet's hemisphere, and even able to contend with Tatsumaki, an extremely powerful S-Class hero that is regarded as the Hero Association's ultimate weapon.

Thanks to the powers received from "God", Garou awakened to the flow of energy and behaviour of all forces in the cosmos; the Hero Hunter also having become capable of fighting against even a serious Saitama, albeit losing in the end.

The Monster Cells generated by Orochi; can also bestow significant increases in power on a human when consumed willingly, by transforming the affected individual into a Mysterious Being. The stronger the human, the stronger the monster transformation will be.

A human touching one of the mysterious cubes is able to contact with "God" and be offered power by it, which transforms them into a Mysterious being if they are worthy enough. But if not, they will face "forfeiture" and presumably die. "God" has attempted to manipulate others into accepting its power by personally appearing before them (or rather, on their minds) while disguising itself as the person whom they seem to respect. It has been shown that the person must at least touch God's hand in order to to receive its power. "God" is also capable of taking back the granted powers along with the lives of the wielders if it so wishes.

Trivia

 * Although God has granted Homeless Emperor the ability to summon and control energy spheres at will, it is unclear if his superhuman speed and reflexes are also from the same source.
