* Yun and Yang are the same age in every game they appear in. Thankfully, their appearances in ''Street Fighter Alpha 3'' and ''Capcom vs. SNK 2'' are non-canon, but even in their ''SFIV'' cameo, they look the same as ever. It really makes you squirm sometimes...
* We don't know anything about Q, or if it's even a him, or if it's even human. He is a creepy looking figure in a trenchcoat with a seemingly metal expressionless face, he breaths heavily and grunts without talking in fights. Absolutely everything about him is unknown, and he could be [[ParanoiaFuel anywhere at any time.]]
** If he's not investigating the murders in his ending, he may very well BE the murderer. And considering the murder sights are the game's stages, it's very likely the people he murdered are [[HeroKiller the rest of the game's cast.]] This especially falls in line with his victory animations, where he either starts crushing their head ([[GoryDiscretionShot the animation is cut off to the results screen]]) or he [[TragicMonster sheds a tear and then moves on]].
* Twelve is overall quite creepy on his own, but what really takes the cake is the ''downright chilling voice'' he has while copying an opponent with the X-Copy Super Art... It must be heard to understand...
