Another possibility is a group of scientists who were working on some dangerous experiments before the apocalypse. Now, they see Clementine and Rick's group as perfect test subjects. They try to capture them using their advanced, albeit somewhat makeshift, technology. They pose a different kind of threat compared to the usual post - apocalyptic marauders, as they are more calculating and have some knowledge that could be used against Rick and Clementine.
It could be a new group of survivors who are extremely territorial. They see Rick's group and Clementine as threats to their resources. This group might be led by a power - hungry man who is willing to do anything to protect what he thinks is his, including attacking Rick's group and trying to capture Clementine.
A cult - like group could be the antagonist. They believe in some strange post - apocalyptic ideology and think that Clementine has some special power or is a sign from their so - called 'god'. They try to kidnap her from Rick's group and force her to be part of their cult. Rick and his group have to fight against this cult to save Clementine and themselves.
One possible plot could be that Clementine is on a journey and stumbles upon Rick's group. At first, there's some mistrust as Rick is cautious of this new young girl. But Clementine shows her survival skills, like being able to track and find food. Eventually, they start to work together to fight off a common enemy, like a large horde of walkers. Clementine also bonds with Carl, sharing her experiences of growing up in a post - apocalyptic world from a young age.
In fanfiction, when pregnant Clementine meets Rick Grimes, it could lead to a very emotional encounter. Rick might be reminded of his own family and be more empathetic towards Clementine. He could offer her his wisdom and guidance. Clementine could share her own tales of survival. Their relationship could develop into a strong friendship or even more, and they could face the challenges of the world together.
Maybe it's a new character created specifically for this fanfiction. A powerful alien scientist who sees Morty and young Rick as a threat to his plans for universal domination. He would constantly be trying to stop their adventures and capture them.
Well, one possibility is that they form a strong alliance. Clementine, with her survival skills, and Rick, being a natural leader, could team up to face the many threats in the post - apocalyptic world. They might share their different experiences and knowledge, which could lead to new strategies for survival. For example, Clementine could teach Rick some of her more stealth - based techniques, while Rick could show Clementine how to better organize a group of survivors.

It could be a powerful dark wizard from Harry's world who has escaped into Wednesday's world to hide and cause chaos.

Maybe a rogue ninja who has somehow tapped into dark powers related to Kami's domain. This ninja wants to use these powers to take over the ninja world, and Naruto, with Kami's help, has to stop him.

There's a possibility that an evil scientist from another planet could be the main antagonist. This scientist wants to use Bulma's knowledge and Cell's power for his own evil experiments.
