This is just to give some history to the real Marinette the and other Marinette's and how they come across meeting you. Take note that I do not own any of the artwork shown below. They belong to their respective artists. Also, i will be giving the other three Marinette's short, but different variations of their names, just to make sure no one gets confused. With that set down, let's get on with this.

[Original Marinette]

Name: Marinette Dupain-Cheng

Age: 18

Looks:

Miraculous:

Kwami: Tikki

Miraculous Form: Ladybug.

Personality: sweet, outgoing, young, and joyful girl who loves fashion, her friends, family. known for catastrophizing and struggles deeply with self-confidence. She holds herself to very high standards and is deeply unsettled by failure.

[How she met you]
She was with Alya talking in class until Ms. Bustier has gotten everyone's attention. She was introducing a new student as everyone was confused as the teacher then called for the new student to enter. The moment she took one glance at you, she began to gain a blush on her face, which Alya joked at silently. It was kinda the same for Y/n, yet he managed to remain stotic as he say behind Marinette. The girl could help but blush internally as Y/n was near her. What she did not know was that Y/n was the Holder of the Cat Miraculous and their journey as Ladybug and Jaded Panther became much more exciting..or complicated.

[Second Marinette]

Name: Marinette Dupain-Cheng

Alternate Name: Mari

Age: 18

Looks:

Miraculous:

Kwami: Sealed Tikki

Miraculous Form: Shadybug.

Personality: Unlike her counterpart, Marinette was not able to make any friends. Because of that, she didn't have the support she needed to stand up against Chloé Bourgeois, whose heavy bullying caused her to develop a bit of depression that led to become cynical and unable to find any joy. The amount of loneliness and sadness in her heart turned her into an easy prey for Scar and The Supreme, who forced her to work for him as the holder of the Ladybug Miraculous. She acts all bitter and sass to everyone around her, but in reality.. she desperately wants to be free from The Supreme and Claw Noir.

After meeting and being with Y/n: Gains confidence in herself, learns to stand up for herself, turns against her captors. Feels joy being with people she can truly call her friends.

Traits: Afraid of Scar hurting her, Bitter, due to the bullying due received from her Chloé and abuse from Scar, very clingy towards the Main character in either a loving way.."Personal" way.

Likes: Being with Jaded Panther(You), being held by him, not being near Scar, helping the Miraculous Heroes do what's right.

Diskikes: Scar, The Supreme, being forced into doing bad things, getting mocked, seeing LadyNoire and Lady Blanc being too close to you.

[How she appears on your world]
She, alongside Claw Noir tracked down BetterFly at his base. Betterfly quickly kamikotizes Alya into Ubiquity, so he'll be able to get help from that dimensions Ladybug and Cat Noir.

However, the dimension travel began to take a turn for the worse as Claw Noir used threw a Cataclysm ball at the portal, disrupting her dimension travel power. While thankfully this dissent kill her, This cause her abilities to go haywire as the energy she is storing to keep the portal stable became too much as Ubiquity forcefully explodes throughout the multiverse.

Shadybug became separated from Claw Noir as she landed onto another world on where our Main Heroes Ladybug and Jaded Panther are at. Would she choose to go back to her home world? We'll see..

Personality: Opposite of Plagg..to an extent.

Akumatized Miraculous Form:

[How she appears in your world]
Marinette was still in despair after what happened to her world..by her own hands. Just like in Chat Blanc(but in similar terms to my version from my Parisian Spider story), this Marinette was once known as LadyNoire that went through losing her version of Y/n from a Akumatized Villain attack, which sadly took his life. HawkMoth, taking advantage of her depressed state, decided to Akumatize her into doing his bidding.

She resisted as much as she could, but her Cataclysm overloads due to her negative emotions of trying not, detonating in a massive explosion that thunderously wipes out Paris and everyone in it, including killing HawkMoth, as well as accidentally destroying the moon with the backblast.

Since then, the Akumatized Marinette of this world wallowed in her misery in the destroyed world, wishing that the nightmare she was in was not real. Just then, she was then pulled into a unstable portal and thrown onto the Canon universe.

And that's that for the Marinette Bios. I am in the work of making the prolouge chapter. Hope you like this.
