* Ayane begins ''Razor's Edge'' by slaughtering a soldier and his mates wheh he tries to to rape her. Ayane is a ChildByRape and not only was she shunned for this her father was such a bastard [[BewareTheNiceOnes her sister]] set out to murder him.
* In case you haven't noticed, in the infamous continue screen for the [[VideoGames Arcade]] game, just before the screen fades to red, if you pay attention you can see, as a FreezeFrameBonus, that [[GettingCrapPastTheRadar the circular saw has started moving]]. Yeah. One can only wonder [[NightmareFuel what the fade-to-red stands for.]]
* One cannot fathom how many innocent people were slaughtered during the widespread fiend attacks in the second Xbox game.
* The recent FlipFlopOfGod regarding the chronological order of the games leads to this. He beginning of the first Xbox game features Ryu in traditional ninja apparel, but after Hayabusa village is attacked, he switches to his modern gear and sticks to it whenever he needs to go on a mission or save the world. Yet in the NES games and the OVA, which have been confirmed by WordOfGod to take place ''after'' the Xbox games, he's back to wearing more traditional armor again.
** Not sure about the other 2 NES games, but the first does have an explanation. Ryu didn't expect to need his black outfit when he went to visit Walter Smith, because he had no reason to expect he'd be attacked. By the time Ryu's fighting off the forces of evil, he doesn't have time to head back to the village to change clothes.
