When G was first revealed in the reflection of Menat’s orb, there was some speculation that he would be related somehow to Street Fighter III: 3rd Strike‘s Q — and only because they both share a single letter name. We now know both men are canonically international phenomenons in their own ways and have eerily similar outfits (well, G’s Story Mode outfit, at least, shares design elements with Q’s main outfit). As Pombear demonstrates, they also share an awful lot in the way of attacks:
Whether they are the same person, members of the same organization, or something else entirely remains to be seen. Of course, “remains to be seen” could be said about most aspects of these intentionally mysterious characters — but we know, if nothing else, that the similarities are far beyond coincidence.
