Contrarians want to feel special in my opinion.
"oh no, it's a character i don't care about, so im gonna call it boring because a lot of people like them!"
Most of the unexpected characters have always been my least favorites. Wii Fit Trainer in 4, Joker in FP1, R.O.B in Brawl (although i warmed up to him) and so on.
The most anticipated characters for me are the most obvious, Ridley, K.Rool, Mega Man, Little Mac. Those bring the hype to me. I guess there's also a "they were inevitable anyway" deal when it comes to characters i don't like. I didn't care for Duck Hunt in Smash 4, but the ESRB leak made me entertain the idea so i wasn't mad, as opposed to see PP for the first time and to this day is still my least favorite character reveal in Smash History. Hell, one of my least favorite gaming reveals as a whole.
Im boring, and im proud of it.
Wasn't Nester in Pilotwings if i remember correctly?
Also wasn't Pilotwings Restort with Miis? At least Mii Costume based on the Pilotwings outfit for those games would be nice.
