It would be awesome to have:
Repunzel and Pascal as a duo, just like Sully and Boo. They could do damage with the frying pan, could heal by singing, and pull people forward with her hair like Woody.
Flynn Rider could do damage with the two random guys that he’s always with. They could do a stampede just like Felix. He could do other things, but let’s get to the next one.
Maximus could do damage by spitting out apples, hitting people with his hoof, etc.
Bulls-Eye could do some of the same stuff as Maximus, not all of them though.
Please give Stitch some company!
Ariel
Simba
Cruella DeVille
Lightning McQueen and friends
Jasmine
Elsa
I could go on, but I’m too tired.
