who do u think is most compatible with ash from pokemon?

I guess misty.

Neither, they all yell at each other all the time. If i had to choose i say a tie between Misty and May.

Misty:They are nice to each other most of the time.
May:She doesnt attack Ash as much as Misty/Dawn

No one.

Misty. They got along some-what, and they seemed to have the best chemistry working together.
