Free Step Dodge

Probably because I am annoyed that he shares his first name with the protaganist of Street Fighter.

You're not the only one. After all he has always been more associated with falcons than with dragons (not always of course), afaik.

Is that a problem? He's labeled in-game as Hayabusa. That's what I call him.

Hayabusa is fine.

Just thought it was strange that some characters are referred to their surname rather than their first name.

Put some respect on his name, Reju Hayebusiness.

All jokes aside, I always call him Ryu Hayabusa or just plain Hayabusa. Busa seems like the lazy way of typing, or maybe I respect the name too much.
