This ability can be obtained by whoever uses both the Ladybug and Cat Miraculouses at the same time. This power is described by Wang Fu as "the ultimate power, the one that shapes reality", and is capable of granting any one wish when an unknown incantation is spoken by the user.
However, the power comes with one known drawback: due to the universe needing to maintain a state of balance, there is a reaction to every wish granted. If someone wishes for something, then that thing will be lost from another person.
- Due to the Power having a description in the Miraculous spellbook, and with Master Fu having knowledge of its effects, it is implied it has been used before as well as the results were probably not as expected.
- Gabriel Agreste's primary goal is to steal both the Ladybug and Cat Miraculouses through his akumatized villains to use their ultimate power to bring his wife Emilie back from her deep sleep.
- If he were to succeed, it could very well end up putting another person into a deep sleep.
- It is possible that if Emilie's sleep becomes permanent, in that she dies, the power could be used to bring her back to life, but likely at the cost of someone else's life.
- It's unknown what will happen to Plagg, Tikki, or either of the jewels after the power is used.
