Project UnDiva: Vocaloid Battle Royale (or perhaps Vocaloid Kinetic Effects?) is a fictitious video game incorporating elements of the arcade games Elevator Action Returns[1] and The Outfoxies[2]. In each level, the player character fights his/her way through a building with many elevators (à la Elevator Action Returns) to find the enemy and then duke it out (à la The Outfoxies).
(Why "Project UnDiva"? It has to do with a real video game based on Vocaloid[3]. Note that the content of this idea is completely unrelated to that Project Diva, though.)
(How do we reconcile this with Joe9320's idea of "love androids"? Mention something about yandere[4] tendencies perhaps?)
Don't worry; I'm not asking anyone to actually develop such a game. Mockup screenshots are fine — ask for help on UN:PIC if needed.
Image editing notes
To enlarge emulator screenshots of a real 8- or 16-bit video game, it is recommended that you use a Scale*x or hq*x filter. Make sure that any Vocaloid images you photoshop in are of a resolution appropriate to the video game system in question. This means, avoid unnecessary anti-aliasing, and do anything necessary to make sure the result of resizing isn't too blurry.
Likewise, if you will be using a screenshot from a more modern video game (or, better yet, an original 3-D rendering), you should enlarge any pixel-art sprites to match. This can be done by
alternating between Scale2x and manual editing. To ensure that Scale2x works as intended, do not apply any anti-aliasing until you are finished with this editing cycle.
Compare Danny and Demi from The Outfoxies[5].
Further discussion
According to the intro text of The Outfoxies, Danny and Demi are conjoined twins who were separated following a train accident. (They are of opposite genders, which is impossible in real life; conjoined fraternal twins would reject each other and fail to be viable, except possibly in certain cases of chimerism.) They are always holding hands, and they still seem to have at least one hand free with which to use weapons. Their appearance seems to be based on that of Chang and Eng Bunker, who were classified as xiphopagus and had four functional arms in total.
How do we reconcile this with the fact that canonically, Kagamime Rin and Len each have both arms intact? Did they suffer an accident shortly before the events of this game? (One possibility: they were riding in a train or bus, holding hands, when the vehicle crashed and caught fire, causing the hands they were holding to be burned and fused together.)
Chang and Eng's names were chosen to mean "left" and "right" in some dialect of Chinese[6]. (Which is which - that is, whose definition of left/right? Also, what dialect?) Likewise, some YouTube commenters have suggested that Rin and Len were named to suggest right and left[7].
Danny and Demi are the youngest characters in The Outfoxies. Similarly, Rin and Len are, in-universe, the youngest (out of which Vocaloids?).
Sourcing issues
The aforementioned Hardcore Gaming 101 website gives the spelling "Dani" and "Debi." Are these transliterations of the Japanese names? (No; see gameplay video excerpt, in which ミ (mi) is clearly shown at the end of one name. Perhaps the names were given differently in the operator's manual and/or cabinet artwork? The latter as shown on MAWSclick on "artwork" is not of a sufficiently high resolution for me to make out the writing in question.)
What does the commonly accepted backstory for Kagamime Rin and Len say about their history of teamwork? (Why do they sometimes work together and sometimes separately? To what extent do they prefer each?)
Edie Burret from Elevator Action Returns looks a bit like Megurine Luka.
See the intro screenshots from Hardcore Gaming 101[1], and also this oneclick on "wallpaper".
Visual similarities categorized
- Hair length and straightness
- Hair color (marginal, only due to lighting in the intro scene shown on Hardcore Gaming 101)
- Headbands
- Bare upper arms and clothed lower arms (although the same can be said of several other Vocaloids. NB: Megurine Luka appears to be wearing gauntlets or bracers, which bear a passing resemblance to ... the control panel of the Power Glove?)
- Bare midriffs (TODO: example, preferably not a YouTube video)
The "Master" represents a user of the Vocaloid software. He is the final boss of this game. His appearance should perhaps resemble that of Professor Ching or Bernard White from The Outfoxies. (Neither of those characters is the final boss of The Outfoxies, but the real final boss doesn't look so cool.)
In the game's intro, the playable characters receive letters from the Master, stating essentially, "I have kidnapped Hatsune Miku. Oh BTW, your friends are now out to kill you. Let's see you solve both problems. Good luck." (Obviously, this means that Hatsune Miku is not a playable character. Perhaps this plot is a desperate attempt to salvage the reputation of the "New Miku" characters or to sabotage the upcoming official English Miku?)
One well-known reference to the Master is in KAITO ga UNINSTALL. TODO: Kaito should also be a playable character — make a section for him here.
