History VideoGame / IdolShowdown

** The alternate palettes of the available characters are based some of their colleagues they've done collabs with. Some of the unlockable palettes are also based on some of the talents' own alternate outfits.

*** In the Collection, Ollie has a poster of Ina and portraits of the [=Holoh3roes=] (A.K.A. [=HoloID=] 3rd Gen) on the wall.

** The starting items for Virtual Frontier are items owned by TEMPUS HQ: Regis's Light Armor, Magni's Glove Cloak, Vesper's Plastic Ball, and Axel's Gladiator Chains.

** Coco's "Next Meme" attack turns her opponent into a meme for a moment. The meme is based on actual memes for each opponent, including (but not limited to) "[[VideoGame/Doom2016 DOOG]]" for Korone, Aki's visible disapproval of pineapple on pizza with an emphatic "[[NoJustNoReaction NO]]", and Fubuki's "[[ThisIsGonnaSuck Ya be]]" face while playing ''VideoGame/{{Phantasmaphobia}}''.

'''Shigure Ui ch.:''' it's maggin time

* FunnyBackgroundEvent: At the end of a player battle and the subsequent RevealShot of the livestream, there's a variety of comments in the live chat of this nature,

'''Eating M. Dyson's a**''': Are you winning, my oshi?

*** In Reine's Virtual Frontier event, Fauna can be seen in the background.

** In a similar fashion, both Mio and Miko can be seen sitting on top of the gate in the Moonlit Shrine stage. If either is being used as a collab partner, they won't be present in the background. Same with Amelia in Gang City

** The Pedas Manja item can be used to instantly win a battle, at the cost of not receiving any rewards at all. A player can strategically use these to skip over fights such as ERROR battles if they are low on HP in hopes of getting to the next rest spot. For obvious reasons, the item is disabled against the final boss to make sure the player actually earns their victory.

* DevelopersForesight: The "Midnight Rose" stage will change who is performing in the background depending on what track is playing, with one of the possible tracks being a version Aki's "Shallys", in which case she and Ashino will be performing it in the background. However, if it plays while one of the players is playing Aki, only Ashino will be in the background.

'''Hakos Baelz''': Bruh\\
My dog just died LETS GOOO

* {{LOL69}}: As you adjust the announcer volume they will constantly speak to let you know how loud they are. Hit "69%" and they'll just say "Nice!"

* HardModePerks: Axel's Gladiator Chains makes enemies hit harder, but increases money gain, allowing skilled players to get loads of cash quickly.

*** In the Collection, Ollie has a poster of Ina on the wall.

*** In her Virtual Frontier event, Reine has a Fauna doll on top of the chair next to her.

** Some Holomems who don't appear as playable characters, assists, NPCs or in Virtual Frontier events still have some form of appearance in the game.

* TheCameo: Independent [=vTuber=] Ashino appears sometimes on the "Midnight Rose" stage, referencing one of Aki's streams where she performed several songs with him providing guitar accompaniment.

** Given that Virtual Frontier ends with [[spoiler: a corrupted Sora as the FinalBoss, the fight taking place in front of a dead tree, and the pre-fight description being an ERROR code]], it's safe to say that the ''WebAnimation/HololiveERROR'' is what's being referenced.
