- About the only thing anybody knows about the original arcade machine is the continue screen which has Ryu is bound to a platform, struggling as a circular saw descends to his stomach while being surrounded by demons. What makes it worse is that the screen turns red at the end of the countdown if you don't decide to continue.
- This isn't helped by the fact that while the rest of the game is fairly tongue-in-cheek and against humans (or at least cultists that are Ambiguously Human), this is the only time in the game you get to see the demons that will take over the world if Ryu fails. It's a nasty Surprisingly Creepy Moment.
- The shadow of Ryu behind a window at the start of every stage, with creepy red eyes before he bursts through the screen and starts the level.
- Jaquio's Nightmare Face in the first NES game and the Baron Spider's White Mask of Doom in The Dark Sword of Chaos.
- How about the Masked Devil
◊ from the first NES game? - Professor Bucky-Wise's One-Winged Angel transformation in the OVA: his skin peels off and he grows a second backbone as his human features fall off (his ears and eyes can be seen falling off and ''melting'', respectively) as he becomes a green skinned Humanoid Abomination. The apperance itself is incredibly sadistic, stabbing Ryu in the arm and crushing Irene Lew's arm when she tries to save Ryu, all the while it's smiling.
