Please don't list this on a work's page as a trope. Examples can go on the work's YMMV tab.
Nightmare Fuel: Street Fighter
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.
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 spottingto keep from getting dizzy, and he's just doing it really fast.
Certain move animations of Akuma's are accompanied with the creepy, otherworldly sound of what appears to be children laughing. This is never explained, but a popular theory is that since Akuma has power over death, this is the sound of lost souls laughing as Akuma condemns his victim.
If anything, Oni may be even worse, considering it's Akuma, but 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 his game over animation, it's implied that he dies.
The defeated portraits in Street Fighter II show the characters suffering injuries ranging from bumps and bruises to bleeding wounds, along with expressions of pain on their faces. A notable example is Blanka, whose portrait made it appear as if his eyes were coming out of his head.
In Super Street Fighter II, take a good look at Zangief's defeated portrait's left eye. Not only it looks like it's about to pop out too, but the socket's bloody as well. O U C H.
The defeated characters' poses in Street Fighter III: Second Impact are also pretty freaky, especially Akuma's and Oro's. The former spits out green blood in a freaky way, while the latter's eyes sockets appear empty, making him look like a zombie.
Some characters, like Urien, look as if they were literally beaten to death. Ken, on the other hand, looks horrendously disfigured.
Imagine rejecting an interview from a pretty woman due to being busy. That's nothing outta the blue, right? Well, then imagine that said pretty woman is actually a Manipulative Bitch (with a Hidden Heart of Gold and her own agenda, but you won't learn anything about it for a long time) who then goes after your spouse, gives her an apparently innocent doll (which is rigged), and later kidnaps said spouse to manipulate you and your best friend, who also is dealing with a powerful Enemy Within of sorts and you cannot do a lot to help him. And also said woman ends up torturing another friend of yours and provoking your best friend into a Roaring Rampage of Revenge caused by said Enemy Within, which only another of your friends can stop though at great risk to herself.The Ties that Bind invokes quite the Adult Fear, and it proves to be quite the nightmare on Ken Masters; now, try putting yourself in his shoes, and you'll see how it's sheer HELL and massively fucked up.
One of the bad endings for one of the Street Fighter Alpha games has the face of a statue in the background of the Thailand stage opening up to reveal a Shadaloo superweapon. Quite a creepy surprise.
