Personally, I sort of see things going either way. Either Nintendo brings back Leslie Swan for Mona or they decide to "capitalize" on WarioWare Gold being the first WarioWare game with EXTENSIVE voice acting, and go with someone more "established" in the voice acting industry.
As for Mona herself, I almost forgot that her mom is a runway model. IMO, it certainly explains Mona's good looks. Maybe she's decided to follow in her mom's footsteps?
That's even why I also support Mona too. I get that Ashley's a witch, and she's got the whole dark magic thing, but Mona feels like she has a bit more freedom to work with a moveset, you know?
BTW, I'd like to thank
@MoonlitIllusion for these Mona for Smash signatures! Honestly, all I really asked for was one that used her Smooth Moves artwork, so it was really sweet of them to do sigs that used her Touched AND Game and Wario art too!
