History NightmareFuel / PumpItUp

** ''Pro'' introduced the song "!" [[LuckyCharmsTitle (pronounced "bang")]], a big beat song with elements from HardcoreTechno. What makes this song more unnerving is the BGA, which tells a story from the perspective of a person suffering from anxiety or depression, having mental breakdowns and being detached from reality as well as his family and friends. [[DiagnosedByTheAudience There's a reason why many ''[=Pump=]'' players say that this BGA needs to seek a therapist.]]
** ''Pro 2'''s [=BGAs=] is a reference to ''VideoGame/InTheGroove'' [=BGAs=], meaning that they would use a sequence of background videos titled "Jump Backs" synced to the music. One of those Jump Backs, labeled as number 628 in the files, depict a blue background and falling binary numbers... accompanied with a [=3D=] face that sticks out of a plane [[EmptyEyes with blank yellow eyes]]. The face moves slowly, to various directions, and even sometimes looks at the player [[ThousandYardStare as if it's staring into the player's souls]]. This Jump Back is present in the current BGA for [[SoundtrackDissonance "Rave Until The Night Is Over (Cyber Trance Mix)"]] as well as "Take Me Back" from ''Pro''/''Fiesta 2'', albeit an edited version.

** The song is also stated to be ported over to ''Phoenix'' in update 1.04.0. If the title card is already creepy, one can only imagine what its BGA will look like...

%% ** The song is also slated to be ported over to ''XX'' in the near future. If the title card is already creepy, one can only imagine what its BGA will look like...

* Any [=BGA=] with a StylisticSuck art style will more often than not turn out creepy. Notable examples include "Jump", "Hate", "Fire Game", "Ugly Dee" and "Hello William" by [=BanYa=], "We Are" by Deux, "Go Away" by BMK and "Typhoon" by D.O., among others.

* ''Infinity'' also gives Doin’s "Says", which uses a generic [=BGA=] in the main series, its own scary background animation. Among all the strange animations, what stands out best is the [[SurpriseCreepy oddly creepy doodled face]] that appears right after the title opening.

* ''XX'' crosses over possibly the greatest contender for creepiest background animation - none other than '''[[VideoGame/{{Phigros}} [=LeaF=] and Optie's [="MopeMope"=]]]'''. Sure, the video was altered to appeal to a more general audience, but both the song and its accompanying SurpriseCreepy animation remain as terrifying as ever.

** Just as the [=BanYa=] songs above, some of the harder charts for this song contained EpilepticFlashingLights that matched those in the original video. Thankfully, they were patched away due to the risk of seizures they posed to players.

* ''XX'' brings possibly the greatest contender for creepiest background animation - none other than '''[=LeaF=] and Optie's [="MopeMope"=]''', originally from ''[[VideoGame/{{Phigros}} Phigros]]''. Sure, the video was altered to appeal to a more general audience, but both the song and its accompanying SurpriseCreepy animation remain as terrifying as ever.

* The title card and [=BGA=] for "Dignity" from ''Exceed'', in both its classic version and the new version made by Lyrebird Ferdinant for ''XX''. The death metal music is already scary enough, but the [=BGA=] is somehow even ''more'' disturbing. The video shows a fanatically crazed man and woman with MindControlEyes staring at a disembodied eyeball, and their eyes are rolling randomly. From time to time, one can see the figures' skeletons flashing by. And while there is a reprieve in seeing the cute bat-winged sheep that became the video's mascot, it's quickly crushed when the aforementioned eyeballs begin chasing it. Terrifying doesn't even begin to describe this video.
* ''Achluoias'' by [=D_AAN=], at the end of the [=BGA=], a figure of woman CreepyDoll appears after the graveyard-induced themes throughout this [=BGA=].
* ''Extravaganza'' and ''Will O’ The Wisp'' by [=BanYa=], has lots of EpilepticFlashingLights.
** ''Jump'' by [=BanYa=] is kinda StylisticSuck, yet the design and animation is creepy somehow...
* Doin’s ''Says'' MV in ''Infinity'' (not in main series until now). There’s a [[SurpriseCreepy oddly creepy doodle face figure appeared]] after the title opening in the MV.
* Prime 2 brought ''[[Music/DreamCatcher Chase Me and Good Night]]'', complete with their already freakish music videos. XX continued the trend by bringing ''Fly High'' and ''You and I'', which complement the videos' story.
* '''''Black Maria'' from Infinity'''. Despite the song having no proper BGA, [[https://youtu.be/ysWJ3IqubHQ?t=79 a distorted female figure]] [[JumpScare pops out of the blue to scare unknowing players,]] [[InterfaceScrew obscuring the game's interface for a few seconds.]]
