Who I think Sonic Characters would main in Genshin Impact:
(Except I don't actually know that much about the Sonic franchise and haven't played Genshin in over a year.)
Amy: Sweet and kind, always willing yo help others, but has a surprising amount of determination and stubbornness. She would main Noelle. (Also, they both have giant, smashy things that like no one else can use. They also both have short hair, which I just noticed.)
Tails: I think he'd main Mika both are intelligent at a very young age ,but need to have more confidence in themselves. Plus, they look alike and Tails with a crossbow is always funny.
Cream - For this one, I was torn between Klee and Yaoyao. I like Yaoyao's plushie more, but I think Cream having Klee's gameplay makes more sense. I eventually decided on Klee for a number of reasons. Such as allowing her mom to be Alice and for her to be close with Amy. Also, I just like the idea of Cream bombing Mondsadt. It's very funny.
