Kyubey (Japanese: キュウべえ) is a character in the Japanese animation "Puella Magi Madoka Magica". It is a mysterious creature with a cute appearance. It often encourages others to sign a contract with itself to become a magical girl. When the contract is signed, the girl's wish can be granted.
The real name is Incubator (インキュベーター), which means "incubator" and is a product of alien civilization. In order to prevent the increase in entropy of the universe and avoid the arrival of heat death, this civilization has developed technology to convert "emotions" into "energy". However, this civilization species itself has no emotions, so it looks at the most emotional human beings, girls, and uses their hopeful hearts to capture the huge energy generated by their hearts changing from "hope" to "despair" (falling from "magical girls" to "witches").
