Capcom just revealed the last fighter in the SFV launch roster, F.A.N.G!
I don’t know any more details about him besides this video now, but I will update this page as they become available.
Update: Capcom has revealed that he is a member of Shadoloo, second in command (replacing Sagat according to the status in his background).
He has a (v-skill) projectile that poisons his opponent, dealing damage for an account of time after it hits you, unless you hit him to end it.
He also has a move (v-trigger) that surrounds him with a poison cloud that damages you just to be in it.
You may have also noticed they announce at the very end of the video who will be released next as DLC in 2016:
He looks so much like Alucard from Hellsing. And then the name, like vampire fangs…
