It's Nintendo, they basically never use AI (I think they asked that company to take down the Galaxy Time marketing site for the Mario Galaxy Movie because it previously used AI for example)
This could definitely be a cool direction. Would really fit WarioWare's running bag of Wario being a greedy jerk and getting punished for it. As long as the assets of the microgames aren't actually AI.
One Wario-like Pokemon that came to my mind was Diggersby, seeing as it's stated to be as strong as a excavator and has a similar-ish build. Skuntank is kind of perfect though, it even shares the color of his overalls.
Nintendo was okay with making Daisy playable in Wonder, so it looks like they are easing up on the idea of letting certain characters appear in the platformers.
Mona is the one I most want playable. Maybe Captain Syrup can be an unlockable...
First thought is making that Crazy Galaxy April Fools thing real.
There's also Pyoro. Even though his games are unlockable in WarioWare, they ported his first game separately to the DSi shop as "Bird & Beans." So maybe a Pyoro collection.
i like skuntank, its face is a butt, its mouth is a butthole, its cry in the games is a fart sound... its perfect
its also underrated as hell with huge underdog energy, same as octillery which is why he is there
