drop some EPIC ideas if you were the new butterfly miraculous holder!! 😆
*disclaimer: when I use the Butterfly miraculous, my name is Nova*
First of all, I'd trap Ladybug in such a way that she has no one to get help from, leaving her with no choice but to surrender...
I'd akumatize myself into Timestalker to unveil the whole French miraculous team's identities, including Ladybug and Cat Noir's. But, I won't rush and work according to a bulletproof plan.
I'd use this information to sabotage and break the whole team, turning everyone against each other, while stealing their miraculouses.
Once I get my hands on all the miraculouses, I'd fuse the Mouse, Horse, Bee and the Rooster miraculouses, then I'd akumatize myself into Omniquity(evil version of Ubiquity).I'd use the power of Sublimation to give myself the power of invisibility, then use the power of Multitude to travel to all the existing universes simultaneously, and use the power of Venom to paralyze the contenders. Then I'd return to the quantic universe and deakumatize myself. Then, I'd use the power of Voyage to travel to New York and Shanghai and follow the same procedure. I'd return to my lair, and divide Kaalki to fuse the Rabbit miraculous(because I can only fuse five miraculouses at a time).
Once the coast of external threats is cleared, I'd use the Rabbit miraculous to travel into the Burrow at such a time when adult and granny Bunnyxs are present together and paralyze them to prevent further intervention.
Then, I'd expose Ladybug's lies to Adrien(just like how Ladybug did with Lila in Volpina), while also revealing their identities to each other.
I'd take advantage of the crisis Adrien is stuck in and reakumatize him into Cat Blanc, restraining the Resistance or anyone from intervening, while holding Ladybug at mercy.
Ladybug, vulnerable and having no one to help her would have no choice but to surrender. bwahahahahhahahahahahaa!!!!
*note: I could have used the Ladybug and Black Cat miraculous from the other universes but I wouldn't know how the wish works there or what is the process of making the wish in those universes(just like we saw in Miraculous Paris) so I have to use the miraculouses from the quantic universe because I know how the wish works here.*
