The only REAL streetfighter in pure game context would probably be Zangief or Blanka. Others have been professionally trained. For instance: Ken, Ryu, and Sean all are of the same Dojo.
I have not forgotten about our match though, although I lean towards Akuma now too, I can even kick ass with Ryu now. (his Super with the punch, punch, than into a dragonpunch very slowly is just too cool!)
but, yes, my Ken will smash your Ryu!!!
