For the Metroid Page, we have this little treat.

◊
Reason: Infamy. Probably the most triumphant example in the series.
As for Mega Man, this.

Since Mega Man has its own page, we can assume that any pic candidates are something you would have to be a fan in order to comprehend the horror. As for non-fans, I'm sure the lighting giving Omega a demonic looking (evil glowing eyes, helmet looking like horns, general murderous blood thirsty expression) appearance should give the general idea. Omega fits as one of the rare examples of Fridge Horror turning into full blown HONF.
Context: Through either people he has personally slaughtered or driven to Ax-Crazy blood lust via his Hate Plague powers (he's so blood thirsty and psychotic that he can turn other normally sane Reploids into murderous psychopaths), he killed 75% of all sentient life on the planet (60% of humans and 90% of reploids). Where the Fridge Horror comes in is that Omega is EXACTLY what Dr. Wily intended the original Zero to be (and in fact he was indeed an Ax-Crazy, blood thirsty Robotic Psycho Path before Sigma cleansed him). As a result, the ensuing fight is symbolic of Zero confronting his personal demons.
this one
looks good to me

He who fights bronies should see to itthat he himself does not become a brony. And if you gaze for long into an abyss, Pinkie Pie gazes Also
From a webcomic. It's already on Monster Clown anyway.
Of the ones suggested so far, Alone in the Dark, from the previous thread.
Edit: ..ah, that was an odd coincidence. Still.

Bumping again after weeks untouched. (Was reminded of my series of High Octane Nightmare Fuel threads by the recent Star Wars one.)
On a sidenote, here is another suggestion; the character-select skeleton from Golden Axe.
For what it's worth, here's the Alone In The Dark one resized and cropped to within the TV Tropes width limit.
One problem with the image (though it isn't necessarily a bad thing) is the logo in the bottom-left corner. Should we look for a version without the logo, or is the current one good enough?
I think we should use a different picture instead for the main page, cause the current picture is just...eh in my opinion.

Crown Description:
Nominations for replacement images:

Since people in the High Octane Nightmare Fuel thread were suggesting to have a thread per subsection rather than one for all of them, I figured I would start separate threads for a few of the subsections.
Anyway, yes I am the user who put up the Ecco one in the first place, despite that Ecco had its own section, but at the time I figured that it was such a clear case of High Octane Nightmare Fuel that it was worth it. However, in the HONF main thread, some have expressed doubts that it was even that scary to begin with: https://tvtropes.org/pmwiki/posts.php?discussion=1294842216073477100&page=5#116
In any case, here are some suggestions for alternatives from the HONF main page: https://tvtropes.org/pmwiki/posts.php?discussion=1294842216073477100&page=6#126
Of those suggestions, I would be partial to Alone In The Dark.
EDIT: By the way, look at the HONF page images for Pans Labyrinth, The Legend Of Zelda, or Web Animation, and a pattern seems apparent that unconventional, unique HONF tends to be more impactful, or at least make for a better image.
