Or is he related to Ryu at all?
Stop giving Ono ideas.
No, Akuma was the brother of the man who trained Ken and Ryu and Akuma killed his own brother.
This is because of that Street Fighter Alpha Generations OVA storyline, is it?
"If there's one thing worse than good men doing nothing, it is they're doing something bad."
At best, you could say that Akuma is Ryu's uncle, seeing as Gouken is Ryu's adopted father.
Hmmm. I'll kill him. I'll kill him dead. Like with, with a, rock or something. Like a, like a stone. -Master Pain/Betty00
Street Fighter Alpha Generations OVA seems to suggest that Akuma is Ryu's father.
But the OVA is not canon though.
well .. gouki is ryu father
Alpha Generations isn't canon. It's not even related to the first Alpha movie. It wasn't even released in Japan!

I wouldn't be surprised if they revealed that Akuma was Ryu's father though.
Apparently Bison is the clone of Ryu's father as well as Chun li being his mother from the future....
