Finn. He's the main hero, so it's very likely for him to be in such a situation. His adventurous spirit makes it a great plot point for him to be transported somewhere new and exciting. Jake is also a likely candidate. His shape - shifting abilities could play an interesting role if he were transported. And the Ice King, because he often gets into strange situations already. His craziness could lead to him being accidentally transported.
One popular storyline could be a character from our world getting transported into the Adventure Time universe and having to adapt to its wacky rules. For example, they might struggle with the magic and strange creatures. Another could be a main Adventure Time character being transported to an unknown realm and trying to find their way back home while facing new challenges. And there could also be a story where multiple characters are transported to a parallel Adventure Time world with a different set of power dynamics.
Klaus Mikaelson is definitely an interesting character to write about. His complex personality, being both a villain and a character with a troubled past, offers a lot of room for exploration. When a new character is transported into the story, their interactions with Klaus can be full of drama and tension.
Obviously, Jake would be one of the main characters Si, reborn as Finn, would interact with. They would go on all sorts of wacky adventures together. Also, Princess Bubblegum. Since Finn often helps her with various problems in Ooo, Si would also be involved in those situations, like dealing with the Candy Kingdom's threats.
There are often the brave and resourceful protagonists. They are the ones who get transported with the aincard and have to find their way in the new world. They usually have some kind of special ability related to the aincard.
Definitely Thor. His god - like powers and his Asgardian charm are really fascinating. I'd love to hear his stories about Asgard and his adventures in the nine realms.
I think a scientist would be really interesting. They could potentially use their knowledge to find a cure for the zombie virus within the game world. They might start by analyzing the infected and trying to figure out how the virus works.
They can start by observing the new world's culture. Just like when we travel to a new place in our world, the OC can watch how the people interact, what their values are. For example, if the new world values honor above all else, the OC can try to uphold that in their actions.
First, make friends with the friendly characters. They can help you understand the rules of that world. For example, if you befriend Simba in 'The Lion King' world, he can protect you from the hyenas. Second, learn the magic or special skills there. In 'Frozen', learning how to control ice magic could be useful for self - defense.
First, learn about the magic rules. Then, make friends with Merlin as he can protect you with his magic.
Frodo Baggins from 'The Lord of the Rings' is a well - known character. He's transported into a world full of danger and magic as he has to carry the One Ring to Mordor. Harry Potter is also very famous. He discovers the wizarding world when he's invited to Hogwarts. He then has to battle the dark wizard Voldemort. Also, Percy Jackson from the 'Percy Jackson & the Olympians' series. He finds out he's a demigod and enters a world of Greek mythology which is like a fantasy world in modern times.
