Who could be the new villains in a Code Lyoko Future Fanfic?

A new artificial intelligence created by an evil corporation. This AI could be modeled after XANA but with more malicious intentions and a greater understanding of human emotions, which it uses to manipulate people.

Another plot could be that in the future, the boundaries between the real world and Lyoko start to blur. The Lyoko Warriors have to find a way to stop this from causing chaos. They might encounter old enemies in new forms and have to use their past experiences combined with new knowledge to save both worlds.

Well, it could be about Ulrich finally getting over his past mistakes in the Lyoko battles. Maybe he has a moment of self - realization and decides to change his combat strategies. He might start to focus more on teamwork rather than his solo heroics.

One possible plot could be that Ulrich discovers a new sector in Lyoko that is filled with dangerous energy fields. These fields can only be traversed by 'cutting' through them with a special virtual weapon. So, Ulrich has to go on a solo mission to find this weapon. Along the way, he faces various challenges and X.A.N.A. - controlled monsters. This plot would focus on Ulrich's determination and his ability to adapt to new and difficult situations in Lyoko.

Another potential villain could be a character who was once a friend or ally of Toki but has been corrupted by the power of code - breaking. This character now wants to use their skills to gain absolute power and will do anything to achieve that, even if it means going against Toki and everything they stand for.

Well, it could be about their adventures together in the virtual world of Lyoko. Maybe they team up to fight against XANA's threats more often than in the original show. They might have some deep conversations about their feelings for each other while hiding from the monsters.

A new villain could be a former Miraculous holder who turned evil due to some misfortune. Maybe they felt betrayed by the Order of the Miraculous and now seek revenge. Another possibility is an alien entity that is attracted to the power of the Miraculouses and wants to use them to conquer Earth.

There could be a new villain who is a master of illusions on a whole new level. This villain could create entire cities within illusions, trapping Spider - Man and making him question what is real and what is not. Another potential new villain could be a symbiotic - like being that attaches itself to other people and turns them into powerful minions. Spider - Man would have to not only fight these minions but also find a way to destroy the main symbiotic - like villain at the source.

One idea could be a story where William, after being rescued from XANA's control, has trouble fitting back into normal life at Kadic. Yumi could be the one to help him through it, and during this process, they discover new feelings for each other. Maybe they have to face some remnants of XANA's influence together, which makes their bond stronger.

The fanfic could explore the emotional aftermath among Hiroki's friends. Yumi might struggle with guilt, wondering if she could have done something to prevent his death. Aelita could be in shock, as she has already lost so much and now another friend is gone. This could lead to some tense and poignant moments between the characters.
