A group of dark elves could be the antagonists. They are seeking a powerful artifact that Donald Blake has unknowingly in his possession. Thor gets involved when he realizes the elves' plan could not only harm Blake but also have far - reaching consequences for Asgard. The elves use their dark magic and cunning to try and outwit Thor and Blake throughout the fanfiction.
The plot might involve Thor being banished to a dimension similar to Earth where Donald Blake lives. At first, Thor's brash Asgardian ways clash with Blake's more reserved and scientific approach. But as they get to know each other, they find common ground. For example, they both care about the innocent. They then discover that a dark entity is trying to open portals between their two worlds to cause chaos. So, they must combine Thor's strength and Blake's intellect to stop this threat and in the process, become great friends.
One can anticipate some epic battles or challenges. Maybe they have to rescue a group of people trapped by a powerful sorcerer. During this, Thor would use his hammer and lightning powers, while Donald would use his wits and whatever resources he can find in his rather strange world. Their combined efforts would be a sight to behold.
It could be an amazing story where Thor's Asgardian strength and power meet Donald's rather comical and often bumbling nature. Maybe they team up to face a common enemy, like a villain who has invaded both their worlds.
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.
It could be a powerful dark wizard from Harry's world who has escaped into Wednesday's world to hide and cause chaos. This wizard might be attracted to the darker and more accepting atmosphere of Wednesday's world and use it as a base to plan his evil deeds. He could try to use the strange and spooky elements in Wednesday's world to create powerful dark magic, and Harry and Wednesday would have to join forces to stop him.
It could be a new Sith Lord. This Sith Lord has been secretly amassing power in the shadows and now aims to destroy the last remnants of the Jedi. His dark powers pose a great threat to Rey and Ahsoka, and they must use all their skills and the Force to defeat him.
A powerful dark wizard or sorcerer could be the antagonist. He might be after the Saiyan's life - force or some special energy that Gohan and Bardock possess. This wizard could use dark magic to create all sorts of obstacles for them, like illusions, cursed landscapes, and powerful minions.
It's really hard to say. Thor has his mighty hammer and control over lightning, which is extremely powerful. But Percy has his own set of skills, like his ability to control water and his combat training as a demigod. In a direct fight, Thor's raw power might seem greater, but Percy's strategic thinking could give him an edge.
A possible main antagonist could be a powerful dark wizard who has somehow learned about the existence of the demigod world and wants to harness the power of the demigods for his own evil plans. He could be jealous of the unique abilities that Percy and Annabeth possess and see them as a threat to his rule in the wizarding world.
It could be the Red Queen. She might see Alice's presence in Mirana's world as a threat to her own power and try to stop their friendship.
