Though I've been silent for a while in this topic, I am still working on Akira. I have been refining his attacks and mechanics, giving him special features when up against my other UNIB and DBFC chars and making more sprites for him.
Ex Specials now work similar to how they do in Melty Blood and Under Night In-Birth. Also, Akira's damage and combo potential has been nerfed somewhat.
Also, here's a small video I made showing off some of Akira's combo potential.
