CLxJames wants to help you understand why, in Super Street Fighter 4 Arcade Edition, Akuma’s ultra 2 can be a good choice. This video shows you quite a few situations in which you might be able to land the move. On the downside, while it doesn’t show the entire ultra animation every time, it does show enough of it in repetition to grate on you a bit. Hopefully the information found within is worth it for you.
Included below you’ll find a 2nd video, by paolomiragli that shows off more Demon Armageddon stuff, but has some of the same follies.
