In " Robostus", Markov betrayed Hawk Moth and tried to steal the Ladybug and Cat Miraculouses for himself to make himself human.Meaning, Gabriel whether he knew it or not in a way he already had the answer to his problem.If so, the same thing could've happened to Emilie but it led to her being put in a coma meaning if taking her energy/life force put her to sleep then, giving it back should wake her up. And yet, it's revealed that when working with adult holders, kwamis "feed" off their holders to sustain themselves but when their Miraculous is damaged they likely take more than they need to sustain themselves in the case of Nathalie when she first used the Peacock Miraculous in "Mayura".Or it could be that he wants the power of all the jewels so no one would oppose him after his wish was made, but in using it like that way somewhere along the endless possibilities Hawk Moth would give rise to his own uprising or the power he had accumulated would destroy him.It is unknown fully what type of power he wants, if it's wealth and riches then, he'd be taking it from someone else who already has it or since he already has it wouldn't work.It is possible that this is another aspect of his wish, in that he has become addicted to power in the course of misusing his Miraculous and would wish for his wife to be returned to him as rulers of the world. However, in Season 1 and in his theme song, his goal was to rule the world.If he were to succeed, in the terms of using the power to stop Emilie's condition from happening, it could cause a paradox where the events that caused Gabriel to use the Ultimate Power were negated, leading to said paradox.In seeing the examples above so far it sounds like the power only moves the problem rather than getting rid of it entirely.If it's 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.If he were to succeed, it is likely that someone else would be placed in a deep sleep in Emilie's place, per the law of maintaining balance in the universe.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.Which is also understandable because wishing magic along with most other forms of magic has a way of being unpredictable and dangerous if the user isn't careful or specific enough.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 and the results were probably not as expected." Ladybug & Cat Noir (Origins - Part 1)": Miraculous: Tales of Ladybug & Cat Noir Theme Song:ΔΆ2. If someone wishes for something, then that thing will be lost from another person. However, the power comes with one known drawback: due to the Quantic Universe needing to maintain a state of balance, there is a reaction to every wish granted. 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. This ability can be obtained by whoever uses both the Ladybug and Cat Miraculouses at the same time. The Ultimate Miraculous Absolute Power is a superpower granted to whoever unifies the Ladybug Miraculous and the Cat Miraculous. According to legend, whoever controls both these jewels at the same time, will achieve absolute power.
