Starlight Glimmer also has a good chance. She has shown great aptitude for complex magic. After her reform, she could be on a journey of self - discovery and exploration. Time travel could be a part of that as she tries to understand the past mistakes and how to prevent similar things from happening in the future. And she has the determination to master such a difficult magic.
Midoriya would be a likely candidate. He's always looking for ways to improve and become a better hero. Time travel could give him the chance to learn from past heroes directly, like All Might in his prime. He could also go back to understand more about One for All's past users and how to master the quirk faster.
Well, it could be Twilight Sparkle and Spongebob. Twilight is the intelligent and studious one in My Little Pony. She would be intrigued by Spongebob, who is clearly a very different kind of creature from Equestria. Spongebob, on the other hand, would be in awe of Twilight's magic and knowledge. Their first meeting might happen when Spongebob is exploring the library in Ponyville that Twilight often frequents. She would start asking him questions about where he came from and what his world is like.
Probably Naruto and Twilight Sparkle. Twilight is the intelligent and curious one in the My Little Pony world, always eager to learn new things. Naruto, with his unique ninja abilities, would be something completely new for her. She would likely approach Naruto first to find out more about him.
Probably Spongebob and Twilight Sparkle. Spongebob is always curious and eager to explore new things, and Twilight is the most studious and open - minded of the ponies. So when Spongebob arrives in Equestria, Twilight would be the one most likely to approach him first, wanting to learn about this strange new creature. And Spongebob would be happy to talk to her because she seems friendly and intelligent.
I think Pikachu and Fluttershy would be likely to interact first. Pikachu is curious and friendly, and Fluttershy is gentle and kind - hearted. Their personalities would make them approach each other easily.
Eleven could be a likely candidate. Given her powerful psychic abilities, she might accidentally or purposefully time travel. Her powers have always been a bit unpredictable, and time travel could be an extension of that. She has a strong connection to the Upside Down, so she might be sent back in time to learn more about its origin or how to stop it.
Happy from Fairy Tail and Pinkie Pie from My Little Pony. Happy is a fun - loving and friendly cat - like creature, and Pinkie Pie is the life of the party. They would likely find each other immediately and start having a great time together, sharing jokes and treats. Pinkie Pie might even teach Happy some of her party - planning skills.
Probably Goku and Twilight Sparkle. Twilight is the smart and curious one. She would be the first to approach Goku out of scientific interest, wanting to understand where he came from and what his powers are all about.
Teresa could also be a likely one. She has a special connection to the whole situation, being part of the experiment in a different way. She might time travel to understand more about her own role and to try to make amends for some of the things she did under the control of WICKED. She could go back to change how she interacted with Thomas and the others in the early days, hoping to create a better outcome for everyone.
Definitely Deadpool and Pinkie Pie. Pinkie Pie's hyper - active and fun - loving nature would contrast so much with Deadpool's sarcastic and often dark humor. They could have some really wacky conversations and get into all sorts of crazy adventures together.
