I love the Guardian-dogs temple intro while Shin Akuma and Serious Takuma talk shit to each other there is a heartbeat. Presentation A+ SNK! Glad they bounced back from near bankruptcy
It has a long time, but, let's go: In the SvC Chaos, the Satsui no Hadou is mentioned as "Murderous Wave". In the Street Fighter series, in the US versions, it is mentioned as "Evil Intent". But the true term is "Satsui no Hadou"(Surge of the Murderous Intent). Of course, the story indicates that is very probably that Akuma could control Satsui no Hadou trough meditation, but, with Shin Akuma, Akuma is almost one with Satsui no Hadou. And when Akuma get to the last level of the Satsui no Hadou he become Oni, which I believe it is his last form, and most powerful as well.
