History NightmareFuel / MegaManBattleNetwork

* Nebula Grey from ''5'', the ''literal embodiment'' of human sin, anger, hatred, and all of it's dark impulses. '''Holy fuck'''. Regal's plan for it is to basically have it corrupt the entirety of humanity into being as misanthropic as he is. Might be ''even worse'' in the manga, where we see it unleash much more devastation and almost destroy every character who tries to defeat it.
* [=CircusMan=] in ''Battle Network 6'', who is literally a life-stealing Monster Clown. He has an attack that the fanbase infamously nicknames as the "Tent Rape Attack". If that isn't bad enough, the first time you see him, you witness him opening his chest to reveal a vacuum, which he uses to absorb and capture one of the two Cybeasts. If that ''still'' isn't enough for you, [[spoiler:he also successfully uses it on [=MegaMan=] later]]! He's basically Franchise/{{Kirby}}, without the power transformation part and hundreds of times creepier.

* The game over screen can be a startling appearance the first time. When MegaMan's health is reduced to 0, he fades out of existence and the text "MEGAMAN DELETED" appears. Since there is no "extra lives" system in this series, it cuts to a screen with the text "GAME OVER" immediately afterwards. The screen in 4-6 is downright creepy, with a more solemn jingle playing over golden text with a pale red background and fast-moving blocks of data.

** It gets a whole lot creepier when [[spoiler:you're forced to break into the desolated area's vault in order for Mega to achieve Style Change, triggering the security system that keeps attacking you as you make your way to the exit. You're technically robbing the website of the last thing it had]].

* ''Battle Network 3'': the attack on Sci Lab. Frankly, it's one of the more realistic depictions of both hacking and terrorism in the series, which makes it particularly nasty, but the fact that [[spoiler: ''YOU'' enabled this]] is probably the worst part.

** Lan's father, grandfather, and [[spoiler: ''identical twin'']] all have the same ''genetic'' heart condition. It's never actually mentioned, but presumably Lan himself and [[spoiler:his son Patch from the epilogue]] have it, too.

* ''Battle Network 2'' features a fight against Chaud and Proto Man, with Chaud vowing to delete Mega Man. Note, Chaud was present when Lan and Mega Man activated the Hub.bat file and developed their link to each other and knows that is Mega Man is deleted then Lan dies. Your rival and sometimes friend is willing to kill you without hesitation.

* The scene where Mamoru nearly dies as a result of a WWW attack on a hospital to steal vital data is pretty nightmarish [[AdultFear in a mundane way]].

* In an AdultFear example, Lan and Mega Man get into all sorts of extremely life-threatening situations to save the world. simply because they're the only ones who can in a world of incompetent authorities who are unable to handle them. This includes taking thousands of times the normal amount of electromagnetic radiation, nearly having their souls sucked out, fighting a literal god, taking down the embodiment of human sin, and escaping half a dozen exploding bases when they should be hanging out with their friends and doing their homework. One can only imagine how their parents feel about the whole mess...

* Also in Battle Network 3, when Alpha is now in the hands of the WWW, for the rest of the game, until you've beaten Wily, you go all over the place with some really haunting music telling you the end is near.
* Battle Network 4: It's a small one, but seeing Dr. Regal destroy the platform Lan was on and Lan just barely escaping death as the platform he was on falls offscreen, coupled with the explosion sound is unsettling.
* Also from 4, the Hikaris' doghouse alarm finally goes off. Somebody's broken into their home. Lan rushes home, nobody's there. He runs upstairs to his room, and finds his mother, BoundAndGagged in the corner of his room. On his computer is a note taunting him about doing much worse. And then you realize there wasn't enough time for the intruder to act if you assume the alarm went off when he broke in, so the implication is that he broke in quietly, went after Haruka, left a note, and then ''deliberately triggered the alarm to get attention.''

* In an AdultFear example, Lan and Mega Man get into all sorts of extremely life-threatening situations to save the world. simply because they're the only ones who can in a world of adult NetBattlers who were supposed to be trained to handle them.

* Lan and Mega entering Yum Square. For reference, Yumland (read: [[FantasyCounterpartCulture Cyber-India]]) is supposed to have the world's largest population of [=NetNavis=]. As they travel through Yumland's Cyberworld, Lan and Mega are confronted by a notable lack of this population, which becomes painfully obvious when they come to the Square, which is [[NothingIsScarier desolate and silent]]. Mega must walk, alone, through the creepy emptiness, past unattended store counters, following the sound of clicking and clattering, where they find the sole surviving [=NetNavi=] who informs them that his entire population ''has just been murdered''.

He's basically VideoGame/{{Kirby}}, without the power transformation part and hundreds of times creepier.

** It should be noted that one of the first ones you meet [[SuspiciouslySpecificDenial denies being "altered"]], which suggests that some asshole ([=ElecMan=], most likely) has been tampering with them and has turned them into ''[[BrainwashedAndCrazy mind-broken suicide machines]]''. And the worst thing is, unless you have the ability to escape combat, you're going to need to destroy each one you come across, because broken programs are some of the most dangerous viruses in the dungeon, continually encroaching on your area and brandishing powerful electric shocks. These poor guys are essentially ''victims of MindRape that Mega has to MercyKill''. WhatDoYouMeanItsForKids!
