*kicks down door* DID SOMEBODY SAY, FIXING KINGDOM HEARTS!?
I am totally down for this! It sounds pretty interesting!
In fact, I have three ideas for this!:
1) A toy that was heading to the Hundred Acre Wood(either having been bought by Christopher Robin or his daughter, idrk if the Christopher Robin movie is canon here or not), but ended up stumbling/falling through a universe crack and ending up in another world. Whoever the toy's linked to will depend on their personality, but the D-Linked person will probably have an opposite personality to the toy.
2) A vain suitor from Agrabah, who ends up falling into a universe crack entirely on accident and wanting to go home immediately after so he essentially can be treated like a god again and get the chance to "win Princess Jasmine's heart"(basically, he's not the nicest character at the beginning, but if he's my character in the RP, I hope to change that!). The suitor also gets D-Linked to a Disney villain(who's possibly Maleficent), so yeah, that's fun! :D
3) A young person from Thebes(or wherever Hercules is from) who idolizes Hercules and wants to become exactly like him, but unfortunately doesn't have the confidence or physical strength to do that. They(they can be any gender, btw)'ll probably be D-Linked to Merida, tbh.
