>>35319831If Incineroar is in Smash Bros, it could explain why the Asian Mist is absent from Incineroar's concept artwork. Sakurai could have felt that such a move wouldn't fit Smash Bros well gameplay-wise, and have reason to ask GF if they would redesign Incineroar's signature move to something that could fit Smash Bros better (or maybe even design Incineroar's signature move himself, but that seems unlikely). That would explain two things.
1) Why Darkest Lariat don't show up on Incineroar's concept art, and why the Asian Mist move is absent from the concept art that's officially released to the public.
2) Why Darkest Lariat animation simply just has Incineroar spin around it in its generic T-bone form, suggesting that it was a rushed last minute addition.
