Author's Notes:
Okay, so this fanfic will be different from my normal ones. This story takes place in a different timeline from the first story in which Marinette is demonised to the point where she is antagonistic to the other characters and if you aren't a big fan of Marinette being a villain then i suggest you skip this one out. As for Goku Black, let's just say he has a legit excuse for being in this world.
Chapter 1: Bargain
The story begins in Zeno's Palace where we see both Zenos watching Miraculous on their Godpads being bored. "This show is kinda boring now" The Zenos complain as the Grand Priest hears them and says "Anything wrong My Lords?" The Grand Priest said as the Zenos complained "This tv show is getting repetitive and boring". The Grand Priest then said "You can just erase everything but then again you won't have anything to watch". The two Zenos then pondered until one of them said "I know" the other Zeno said "What". "How about we send someone crazy strong to get rid of everyone". "If that's what you wish then pick someone you want to send" The Grand Priest said as he pulled out another Godpad with various fighters. "I wanna pick Goku." Present Zeno said as the other one said "Me too, but i think he went to train with Uub i think" Future Zeno said. "Oh right, i forgot" Both Zenos were then disappointed when suddenly they found a worthy candidate. The Grand Priest looked over and said with a worried face "Are you sure you wanna pick this one?". "Yes, this one is almost as strong as Goku, if not even more crazy strong". The Grand Priest then summoned the guards and ordered them to release their candidate from their dungeon. The Guards then entered the dungeon, passing through each cell until they found who they were looking for. He was a male Saiyan who looks like Goku except he was wearing Clothing similar to a Supreme Kai's but with a black and red color scheme and had a yellow halo hovering over his head. This man was Goku Black. The Guards opened Black's jail cell when Black lunged forward and rammed into one of the guards and attempted to flip him over when the other guard karate chopped Black which knocked him out. The two Guards then carried Black over to the Grand Priest who ordered "Wake up". Black suddenly woke up and saw both the Grand Priest and the two Zenos. "Why have you brought me here" Black growled when he suddenly eyed the two Zenos "Are those two really the Omni Kings, why are these children even gods to begin with?" Black then turned his attention over to the Grand Priest who said "The two Omni-Kings have decided to send you to destroy the inhabitants of this world which they have created". Black said "And if I refuse?" "Then you would offend them both and have your soul destroyed". The two Zenos eyed Black forcing Black to say "Fine, but is there anything in it for me?". "If you will destroy everyone in the Miraculous tv show, then i will grant you freedom and you will be able to do whatever you please afterwards". Black then thought to himself "If i annihilate everyone in this "TV Show" then i will be able to get revenge on those miserable Saiyans, especially that bastard Trunks". Black then chuckled and said "I'm in". "Good, but you only have about 3 days to do this task". Black then said "Trust me, it will only take an hour just to destroy one little city, i should know". Black was then zapped into the Miraculous dimension where he was then contacted by the Grand Priest that he can use everybit of his power to entertain the Zenos while he Black destroys everbeing in this dimension. Black then agrees and charges up a Black Power Ball and launches it at the Eiffel Tower which crashed below on several hundred civilians. Goku Black then laughed maniacally as he flew around Paris blasting everyone he saw. Meanwhile at the highschool, a blue haired girl was secretly stalking her crush when her friend beside her said "Don't you think this is getting a little bit creepy?". "Like I care Alya, someday me and Adrien will be married, besides aren't my best friends supposed to support me". "Yea but not like this Marinette, i'm starting to think you're even worse than Chloe, at least she has boundaries". "Don't you compare me to CHLOE!" Marinette roared as everyone suddenly heard this and Nino said "Chill out, Marinette". "Nino's right Marinette, you need to either come down or i will call my lawyer to get a restraining order on you". Marinette growled and said "We will get married Adrien, don't you dare forget it". Marinette rushed off with Nino saying "What's with her recently". Adrien said "I don't know Nino, but something tells me she is gonna do something stupid sooner or later". Marinette then pushed both Mylene and Rose out of her way and they both said "The hell's your problem Marinette" "Oh I'm sorry, i had no idea you were a bunch of complainers" Marinette sneered with both of them getting really angry enough so that Hawk moth starts sensing their rage and sends several Akumas to akumatized them and they start turning into Horrificator and Princess Fragrance. Meanwhile, Goku Black was still killing every civilian he saw when suddenly he sensed a negative signature not too far off "What is with this energy, it feels like Anger and Rage, hmph such a primitive power, i will erase this being with this energy from this world" Goku Black flew towards this energy until he finds Hawk moth. "Who are you" Hawk moth ordered before Black grabbed Hawk Moth by the neck and said "So you're the heretic with this spiteful power". Goku Black then ripped off Hawk moth's head and blood started gushing out everywhere when Natalie walked in and screamed at the top of her lungs. Goku Black then created a massive Ki-Blade and rushed forward to chop her in half.
