Who could be the villain to akumatize Gabriel Agreste in a fanfiction?

Maybe the guide is a time - traveler. Someone from the future who has seen the consequences of Gabriel's actions and comes back to try and change the course of events. This time - traveler would know all the ins and outs of what's going to happen and could guide Gabriel towards making better choices. They could show him the destruction his actions as Hawk Moth will cause and offer him an alternative path to achieve his goals in a more positive way.

Well, perhaps Gabriel discovers that Adrien has been secretly helping Ladybug and Chat Noir. This betrayal, in his eyes, could lead to his akumatization. As an akumatized villain, he might have the ability to create dark illusions of everyone's worst fears. He uses these illusions to try and break the will of the superheroes and force them to reveal their identities. He could also use his power to turn the citizens of Paris against Ladybug and Chat Noir, making it even more difficult for them to operate.

A time - traveler from the future could also be an interesting main villain. This character could have seen a dark future where the Miraculouses were misused and has come back to the present to destroy them all. But in his quest, he doesn't care who gets hurt, and Emma has to stop him from changing the past and future in a bad way.

One possible plot could be that Gabriel Agreste, in his search for a way to achieve his goals (maybe related to his fashion empire or his secret identity as Hawk Moth), gets help from an unexpected guide. This guide might be a character who has unique knowledge of the Miraculous or the hidden aspects of Paris. For example, the guide could be an old acquaintance who has connections to the magic that surrounds the Miraculous. They might lead Gabriel to discover new powers or secrets that could change his approach to his plans.

One great fanfiction is 'The Secrets of Gabriel Agreste'. It delves deep into his motives and the backstory that we don't often see in the show. It gives a more complex view of his character.

The fanfiction should also fit well within the world of Miraculous Ladybug. It should respect the existing lore and character relationships. If it can add new elements to the story while still feeling like it belongs in the same universe, that's a great sign of a good Gabriel Agreste fanfiction.

In the 'Chat Noir Confronts Gabriel Agreste' fanfic, Chat Noir might finally expose Gabriel as Hawkmoth. He could use his cataclysm to threaten Gabriel into revealing his true identity and his motives for being Hawkmoth. This would be a huge turning point in the story as it would end the mystery that has been building up throughout the series.

Well, a fanfic about them falling in love might also focus on the internal struggles they face. Gabriel is so focused on his goals related to the Miraculous that he might initially resist his feelings for Nathalie. Nathalie, on the other hand, might be hesitant because of her position as his assistant and the power imbalance. But as the story progresses, these barriers could be broken down, leading to a beautiful and perhaps bittersweet love story.

I'm not sure. Maybe some die-hard fans of the show or those who are really into creating fanfiction.

Plagg, Chat Noir's kwami, would surely be important. He could offer advice to Chat Noir on how to deal with Gabriel. Maybe he has some knowledge about Gabriel that he hasn't shared before. Also, Adrien could be a significant character in the background. Since he is Gabriel's son, his presence or the threat to his well - being could influence the confrontation. And don't forget Nooroo, the kwami of the Butterfly Miraculous that Gabriel uses. He could be a wildcard in the confrontation, perhaps trying to break free from Gabriel's control.
