- Seth is completely naked, but his cybernetic implants manage to hide his unmentionables. Full-Frontal Assault, indeed.
- Subverted just slightly in one of his downloadable alternate costumes: it gives him pants and boots, which eliminate the first part, but contribute more to the second part due to the pants being extremely tight.
- His Ultra Combo from IV. If he can do that, imagine what else he could do to you.
- The BLECE weapon Seth is working on is a pretty gruesome thing. It releases an energy that causes cells to boil and explode.
- In his Big Bang Tornado, Rufus starts to spin on the place really, really fast. While doing so, however, it looks like his head is standing perfectly still, watching at the player with scary, evil eyes. If you look closely when the game goes into slow motion though, you can see him spinning his head. He's just spotting to keep from getting dizzy, and he's just doing it really fast.
- This game's version of Evil Ryu. Remember in Alpha when he was just tanned with a black gi instead of a white one? A rather badass palette swap. Here? He's got Shin Akuma's torn purple gi instead (ala Super Saiyan Goku vs Frieza), spiky red devil hair, glowing red eyes, elongated canines, and a huge hole burned in his chest with Akuma's flaming symbol burned into his back, both of which spout lava . He looks like a zombie straight out of Resident Evil or like Akuma merged with or hijacking Ryu's body Xehanort style.
- One has to wonder what happened to Juri to make her the really crazy way she is. She's plenty of this already in game canon, considering the way she hits on her victims before she beats the tar out of them.
- The deal with the Dolls is already scary, but Decapre's side of it is even worse. Not only she's the only of the non-Cammy Dolls who wasn't kidnapped and brainwashed, but she's a *clone* of Cammy, meaning that unlike the other girls, she doesn't have a past life or anything outside of constant experimentation by Shadaloo. And this is made worse because after the deals in Alpha and the beatdown from Juri, her body is decaying and she's about to die. The effects on her body and mind are terrifying.
- Although SFIV's Ultra attacks often contain Visual Effects of Awesome, some of them are executed so brutally that you have the instinctive urge to wince every time your chosen character is subjected to an Ultra.
- Oni. He's basically a blue-skinned, demonic version of Akuma, except this time there are No. Holds. Barred. Even worse are his victory and game over animations. If he wins against a character, you'll get to see the lighthearted depiction of Oni slamming your character into the ground as they have a near-dying expression on their faces. In the losing character's game over animation, it's implied that he/she dies.
- The fate of the Dolls in IV. In Alpha III they had a Hope Spot in E. Honda's ending, where he gives them a place to stay and teaches them sumo wrestling. Here, they are stored in capsules while unconscious, subjected to a brutal Curb-Stomp Battle by Juri (who also uses Juni as a human shield in a fight against Cammy), and presumably subjected to experiments by Seth until they expire. Juli and Juni manage to escape their fates, but Juli is near-catatonic and completely unable to respond to external stimuli, while Juni, who got off lucky by comparison, is so traumatized by her past ordeals that she can't remember anything.
