To this day, the best one is 3rd Strike’s for adding the fires of Hell. Nothing more beautiful than having a demon’s power emphasized by its native element.
One important contribution of extra style points in the later 2d games was keeping Akuma in the same pose and with the symbol on his back. In the early forms of the super, he just reset to the normal standing pose as the symbol fades out. But since the ps3 gen the part about the finishing pose became inconsistent depending on the game.
in Megaman X Street Fighter (an oficial fangame) exits a secret fight against Akuma (he kills Bison there too) he can does the Raging Demon and it's a insta kill attack In the first Capcom vs SNK exist too a special fight in that he kill Bison but without Raging demon
Since June 2012, this channel had the Art of the Raging Demon. ...but I still wonder where is volume 5 that was teased forever ago with the Street Fighter Alpha Anthology with Sakura's version?
What if Morrigan's Darkness Illusion super is a Raging Demon but just a little slower and with the lights still on? The input is the same style. Demitri also has a super with a similar input style and that could count as a Raging Demon forgetting to turn the lights off. And the same logic for Skullomania's trademark and iconic super.
