This idea came to me out of complete random because I was bored. This is of Megaman's dog Rush doing the Hadoken. And well, I guess... Why not? I mean after all, if there's one thing that Megaman and Street Fighter have in common is that they're both Capcom franchises. And besides, the Hadoken was accessible even in the first Megaman X from 1994. And of course, in Megaman X4, the Maverick boss Magma Dragoon referenced Street Fighter by his "Hadoken" and "Shoryuken" moves. The only move he didn't do was the "Tatsumaki Senpuu Kyaku". Also known as the Hurricane Kick. But think of this as a little homage to that.
