His normal moveset has plenty of attacks to fill a Smash moveset and no other VF character uses anything other than regular martial arts so I don't see them having an edge over Akira in that part.
His specials seem kinda obvious to be. Tetsuzankou has to be there and Renkantai would be his up special. Mouko Kouhazan and Byakko Soushouda and/or Kaiko can easily be the rest of his specials. Akira may be unlikely for a lot of reasons but a lack of moveset is not one of them.
Oh I don't mean to claim that Akira is unlikely. It's definitely an assumption due to a lack of context, prior decisions, and the fact that I got hit with "we're adding this other guy instead of the obvious choice (which is the character I actually wanted) because reasons*" three friken times in this pass.
That and I didn't find many moves on his move list that screamed "special move". For example, Tetsunzankou is just a shoulder check without any immediately observable special properties (and there's also a fairly standard looking combo with the same name I think). I think I assumed it would be his Dash Attack or something. I did get
some ideas as to how his special moves could work, but it looked like they were all combos off of normal moves so I wasn't really sure how they would handle them.
I suppose you could lean into this and just do the 8-way tilts thing with the Special Move button as well so he has 18 normals; some with special properties, and some without (like, his Special Up Tilt would also double as a recovery move when used in the air or something). Might be a bit overcomplicated though (which is probably why they didn't do it for Kazuya like people kept proposing before his reveal).
In conclusion: I dunno.
*I feel I should clarify that I don't have any animosity toward Kazuya as an inclusion, I just couldn't get excited for his reveal because I had absolutely no idea who he was, unlike Hehachi, who was "the Tekken guy" in my brain. To be fair, my knowledge of Tekken characters is probably kind of weird since I didn't recognize Kazuya, and would have had to get my memory jogged a bit on Jin, but I would have instantly recognized Bob.
