If Incineroar is the final non-echo fighter, I will be disappointed. Not only because of my natural bias towards Rowlet/Decidueye (love you, Mom!), but I have always found its design to be unpleasant. It's also a Fire-type, and Smash has so. much. fire. (I mean, Simon's holy water generates fire! C'mon...) It may end up being great fun to play as (I had wanted Krystal, and I was disappointed when we got Wolf, but I ended up loving playing as Wolf), so I'll hold out hope for that, but yeah, disappointed.
It's kind of funny, back in Brawl speculation, there was only one video game character I rejected when other fans wanted him: Geno. I thought his fans were completely irrational, ignoring his very minor status in Nintendo and gaming history, and the complicating factor of his third party status ("He counts as a Mario character, not a third party!" Um... that's not how it works...). Now, with the potential of Incineroar being the final non-echo, one of my first thoughts was, Aw, no Geno?
