What new characters you want to see in Mario Kart 9?

Since Goomba now appears playable in Mario spinoffs, just make him playable.

Hammer Bro is a character I always wanted to become playable; being one of the iconic Mario enemies.

Charging Chuck; really cool enemy. Want to see them not only in Mario Kart, but in the mainline Mario games as well.

We have Petey Piranha and King Boo playable, I would like to see another Mario Boss playable, that being King Bomb-omb.
