Fanfic / Sonic Holograph

"May the bonds you’ve formed become your power, and let the Light of Hope shine forth!"

Sonic crosses over with Hololive.

A Crossover story creating a brand new Alternate Dimension to line the Sonic video game universe, populated by the re-imagined cast of hololive.

The story is being summarized via a Masterpost Document by AU's creator Juddy, also containing bonus material such as written concept pieces, a timeline, a character sheet and a link to the Sonic Holograph Discord server.

Artwork and character bios can also be found on the Holograph Moment on Twitter.

The series currently has 5 stories that make up a larger first 'Saga', with more planned for the next.

On the 25th of May, 2022, a public Discord server was made for the creators of the AU to engage with the community. Starting on the 27th of that same month, daily character bios were posted in order of character appearance. These contain trivia both pertaining to the characters in-universe or facts relating to the project's development.

Saga 1: Light of Hope

1. Sonic Holograph
2. Sonic Holograph: Myth
3. Sonic Holograph: Blazy Mix -Plasmagic Seasons!-
4. Sonic Holograph: Episode Shadow -Stardust Song-

---

Tropes:

• Action Girl: Given the Improbably Female Cast, almost every important girl in the story shows shades of this.
• Adaptational Context Change: A particular favourite of this AU, taking advantage of the various Hololive media streams such as music, animations and of course livestreams to weave in references that either serve as cute nods to the source material all the way to the occasional One-Liner. Sonic examples are also present, though due to the nature of these stories taking place after Sonic Forces, there is currently no arc dedicated to adapting certain parts of the Sonic lore. Examples include:
  • During Kiara's speech to Calliope in Myth, she mentions that Calli always tries to present herself as the 'big-headed bad guy' so that everyone else can rally against her and feel unified. This specific wording is taken from 'guh', a real song by Calliope's virtual idol counterpart Calliope Mori.
• Adaptation Deviation: Hololive's lore and tone is already wildly different depending on the continuity, with Holograph's story borrowing from all facets of the group's various depictions to make them fit the world and tone of Sonic.
• All There in the Manual: The character bios for each story were first written and posted daily in the public Discord server and were later reformatted into images to go up on the creator's Twitter page. These bios contain all sorts of details about the cast, their personalities and little details about them.
  • The original Discord versions also have a Trivia section that was omitted from the Twitter versions due to lack of space, providing additional out-of-universe facts about the development of the characters or other information pertaining to the world.
• Artistic License – Physics: Juddy has confirmed on the official Discord that Planet Taotao is shaped like a peach. Nothing seems to be all too weird from what is shown, but in reality, such an awkward shape would make its gravitational pull a total mess, as the gravity would be rather uneven and make people naturally slide into the crease if near it.
• Bad Future: Multiple are discussed, shown or hinted at:
  • Plasmagic Seasons!! has it's bad ending, an alternative scenario in which Blaze refuses to give back the power of the seasons she gained across her adventure yet still wishes to have her original pyrokinesis restored. After skipping over the implied events of ''Resistance'' for spoiler reasons, we see Blaze return home and a montage depicts her gaining incredible power thanks to her pyrokinesis, season powers and the power of the Sol Emeralds. Unfortunately due to the nature of the Sol Emeralds requiring a proper Guardian to keep them in check lest they cause worldwide natural disasters, Blaze's newfound power has the effect of making the maintenance of her planet much more stressful than before on account of her mind and body now being a tricky balancing act to control properly. Sure, now she can control the weather and natural forces of her whole world actively rather than just preventing them from falling into disaster, but control is an addictive thing... One which Fauna, the Anthropomorphic Personification of Nature is in opposition of. After failing to convince Blaze to return the power of the seasons as it does not belong to her, the two fight and Blaze wins thanks to Fauna losing much of her power due to being in a world that is not her own, only able to draw a small bit from the wormhole she was sent through. After Fauna retreats, we see a shot of Blaze swirling with the power of the Sol Emeralds, filling them with Plasmagic and transforming into Blaze of the Equinox: A nigh-godly figure that commands all of nature.
• Bizarre Seasons: Blaze's first adventure in the Holo Dimension sees her dealing with these at every turn, on a quest to right the energy of the seasons being used and abused on a multidimensional scale. Humid, dinosaur-populated jungles have become winter wonderlands, cities have become engrossed in endless summer fun and despite what you might think, the Demon Realm is supposed to be having a lovely and temperate springtime right now.
• Cool Gate: Rabbitholes, also known as the Rabbithole Phenomena. These spatial anomalies act as gateways to other dimensions and are the root cause of most arcs in the first Saga.
• Cute Bruiser: Kanata the Hamster, a literal angel who goes to a supernatural school to learn healing magic... Is introduced by her punching through hordes of robot invaders with her bare hands. Despite her size, role and powers, Kanata wields noteworthy physical strength that often surprises her opponents and allies alike.
• Cute Little Fangs: From both sides of the crossover. Examples include Blaze, Towa and Nene.
• Department of Redundancy Department: 'Galactic Starlight Corps', Nene's name for Shadow's space crew in Stardust Song is a little bit of this. It ends up sticking, however.
• Difficult, but Awesome: Not only does the Shining form require the user to be in a world with ambient Aura Energy and have a means of focusing it through themselves, but they also require an emotional resonance to amplify its positive charge. While this - along with the fact that the transformation takes a bit of time - makes it an absolute pain in the neck to access on the spot, it is more than worth it, as the result is a Super-tier form that is also entirely self-sustaining if kept within a dimension with ambient Aura due to acting as a perpetual motion machine.
• Distaff Counterpart: Sora and Nene are loosely this to Sonic and Shadow, respectively.
  • Sora is:
    • Associated with the colour blue, with red accents.
    • A heroic presence many look up to.
    • Surprisingly adept with a sword (remember, none of Sonic's friends know for sure he went on an Arthurian adventure and picked up swordplay, and Sora is an Idol Singer who has never actually had to fight a day in her life, so it's equally surprising when either whips this skill out).
    • And her name starts with an S. For bonus points, 'Sora' means 'sky' in Japanese, and Sonic is often metaphorically compared to the wind.
  • On the other hand, there's Nene:
    • An alien who heavily resembles a normal anthropomorphic animal (she hails from Planet Taotao, with the only hint at her origins being her incredibly long tongue, inspired by real Sun Bears and taken to an even wilder level).
    • A fan of driving fast vehicles, comparable to Shadow's use of motorcycles, buggies and various military machines in Shadow the Hedgehog and Sonic the Hedgehog (2006).
    • Though she is silly, optimistic and hard to put down, when push comes to shove she shows just as much grit and determination as Shadow against seemingly impossible odds. When he asks her and the rest of his team to turn back on their quest and leave him to go it alone, she stalwartly refuses.
    • In relation to the whole trope, she and Sora are both female bears paired up with male hedgehogs.
  • Nene and Sora also act as Foils to their narrative counterparts. Sora is a famous idol with little experience while Sonic is a seasoned adventurer with little taste for unwanted attention. In contrast, Nene is a bright ball of optimism that balances Shadow's often juxtaposing stoicism and seriousness when he's acting as the Only Sane Man in his space crew during the events of Stardust Song.
• Gemstone Assault: Aura Energy in physical form is depicted as crystal, meaning those juiced up on said power such as Shining Sonic gain the ability to expel Aura projectiles as physical crystal missiles rather than some form of energy blast.
• Hair-Contrast Duo: Shadow and Nene, with Shadow's dark quills and Nene's bright fur. While Shadow is the Only Sane Man aboard the MoonRabbit at times and is always the most level-headed of the group, he also has a troubled past and occasionally still wrestles with deep-rooted anger issues that have caused him to lapse into violent episode. Nene, on the other hand, has led a pretty comfortable life and her dream is as simple as seeing the galaxy and making lots of friends - she's always uplifting others with her bright positivity and is willing to entertain even the most outlandish of plans when not offering up some of her own.
• Healing Hands: Kanata's healing magic.
• Hopping Machine: The aptly-named 'Hopper' Badniks, a sort of rabbit-shaped lump with a spring mounted to it's underside and a very angry face. One of them falling through a Rabbithole while transporting a small Aura Crystal is the inciting incident that leads Sonic on his first adventure in the Holo Dimension. They're based on the Pekomon, small rabbit-like orb creatures that represent Pekora's fanbase.
• Human Cannonball: Sonic is no stranger to making one of himself and readily does so in Minato Landing Zone to navigate Marine's pirate fleet. Later, when Ninjin Village is attacked by a giant shadowy dragon, he once again fires himself out of a cannon while spinning with Anya to saw right through the beast and out the other side.
• Idol Singer: Despite the reinterpreted Hololive characters not all being idols in this universe, Hololive as an organization still exists and employs those who's original lore was about them being idols from the get-go. Sora the Bear, AZKi the A.I (who is quite literally a virtual idol in this sense), Suisei the Hedgehog and later Roboco the Android are genuine idols even in this continuity.
• "I Know You're in There Somewhere" Fight:
  • Sonic discovers that the lava monster in the Obsidian Cavern Zone actually Bibi, Towa's beloved guardian sprite after being experimented on by Doctor Eggman, only needs someone strong enough to best him in combat to make him stop long enough to calm down. It becomes peaceful after resting and later returns to assist the other characters during the final battle.
  • In Myth, however it takes poor Gura almost the whole adventure and multiple fights before Sonic and Anya can finally cut her free from the control of Entropy. The entire time, Gura's friends are watching on and hoping beyond hope that Sonic can bring their loved one back to them without killing her. Once she's free, Gura immediately tries to set things right by recovering her trident and using it in the ritual to unlock Sonic and Anya's Sacred forms.
• Improbably Female Cast: A holdover from one of the source medias involved in the crossover is the overwhelming amount of ladies featured in major roles, which is especially noticeable when the girls of Sonic are fewer and often restricted to far more supporting positions in any given narrative.
• Interesting Situation Duel: For his final battle against the Planet-Eater in Stardust Song, Shadow asks Sana to send him and the great monster to the farthest reaches of the universe, so that nobody can get caught in the calamity that might arise from their clash. He then proceeds to fight a ravenous monster the size of a celestial body itself on the very borders of known existence within that dimension.
• Lesbian Vampire: After being corrupted by the essence of Autumn and turning into a drama-drunk vampire-witch embodying the spirit of Halloween, Choco acts more openly flirtatious with Mel to spice up her kidnapping. Mel isn't exactly bothered by this, and the relationship between the two Hololive idols these two characters are based on is known for being tinged with heavy flirting. Somewhat inverted from the usual application of the trope however, as Choco (temporarily given vampiric traits via a transformation) is the one capturing and 'preying' upon Mel (a natural born vampire who is nonetheless at her mercy).
• Move in the Frozen Time: Eggman to Sonic after he first reveals his Aura Armour. Now that he's running on the same energy as Sonic's powered bracelet, he's become something of a Time Master (see below).
• Necromancy: A study of magic taught at the Demonic Realm Academy is necromancy, the art of death. While it is capable of traditional feats such as raising undead minions, it is also shown to be applicable as raw magical attacks with a spooky, unholy flair.
  • Rushia is a necromancer who was studying at the Academy, but was scouted by Calliope to act as one of her inner circle of generals some-time before Myth alongside actual reanimated zombie Ollie.
  • Calliope the Reaper, as her name would suggest, is something of a master of this art and is capable of summoning hordes of her skeletal soldiers: The Dead Beats.
• One-Steve Limit: Averted. Marine the Jellyfish, a reinterpreted Hololive idol, has no relation to Sonic the Hedgehog's Marine the Raccoon. They're even both pirate wannabes, which makes Sonic initially nervous when he hears that a 'Captain Marine' is causing trouble during the events of Myth.
• Pirate Girl: The aforementioned Marine the Jellyfish, who appears as a minor antagonist in Myth.
• Rescue Introduction: Comes up quite frequently across the series as a means by which to get acquainted with the large cast.
  • The first outing has Sonic rescue Watame and Sora from Eggman's robots;
  • Plasmagic Seasons sees Blaze saving Mel from the clutches of an overly dramatic witch and Matsuri from a curse of endless partying;
  • The trope is actually inverted with Haato and Fubuki (Haato is just waiting for her sister to come back and Fubuki is an active combatant trying to do essentially what Blaze is doing with less success thanks to her decidedly not being the protagonist);
  • Various members of Shadow's crew in Stardust Song are people he rescued from the planets visited along his journey.
• Ridiculously Cute Critter: The Creatures of Aur, magical beings created as a result of ambient 'Aura' energy affecting their evolution from normal animals and objects over time. Their name is derived from the Sonic series Chao, another example of this trope named after their home franchise's power system of 'Chaos Energy' with the final letter chopped off.
• Rooftop Confrontation: In Myth, Sonic faces off with Calliope at the top of her stronghold's tallest tower, the heights of which separate it so far from the other areas that it's classed as it's own stage: Memento Mori Zone.
• Signature Team Transport: The MoonRabbit, a spacecraft built by Usaken and the vessel of the Galactic Starlight Corps during Stardust Song.
• Space Master: Sana the Speaker, Anthropomorphic Personification of Space and known for performing all kinds of feats using her complete dominion over such a powerful universal concept (such as sending the sealed container housing the essence of the Time Eater into an unreachable void).
• Space Pirates: The secondary antagonistic faction of Stardust Song is a group of these, in particular a crew of dim-witted rusty scrap robots that are barely able to hold themselves together thanks to their shoddy self-maintence skills. They're also Canon Foreigners, being original to this continuity (though their visual design was inspired somewhat by Captain Metal Sonic and his crew).
• Spoiled Brat: Luna the Honeybee, whom Sonic meets during his first outing in the Holo Dimension. Due to her small size, lack of stamina and genuine laziness, she refuses to walk after he rescues her from Eggman's robots and demands to be carried. When Sonic offers her a piggyback ride, she outright refuses and insists she be 'carried like a princess' ^note this is admittedly somewhat justified though, when one considers Sonic's species . Although she's making Sonic wait on her, she does at least lend a hand by slowing his fall at each jump by flapping her wings, lightly inspired by a different insect princess from another platformer.
• Star-Spangled Spandex: Hoshinova, the Goddess of the Moon, seems to turn those she makes her hosts purple, this purple being decorated with actual twinkling stars. Applies to Moona the Rabbit (though the stars don't always show) and Shadow the Hedgehog when in his Nova Shadow form.
• Theme Music Power-Up: Inverted against Sonic in Myth, when he breaks Calliope's mask and her battle theme suddenly starts being a lot less instrumental.

Can't turn back time
I'll always be a prisoner to my ambition

— Red, Calliope Mori

• The Artifact: The career of an idol does not last forever, and while Sonic Holograph has thus far refrained from introducing any characters based on idols that no longer work with Hololive Productions, there are some examples of talents who have left the company for varying reasons since the story's conception. These characters, who's roles were already decided in the story, have not been removed out of respect for the time and effort they spent working as idols for the benefit of their fans - even if it lowers the chances of gaining official recognition from the real idol agency in some regards.
  • Coco the Dragon is based on Kiryu Coco, who graduated in 2021.
  • Rushia the Butterfly is based on Uruha Rushia, who prematurely left following her termination in 2022.
  • Sana the Speaker is based on Tsukumo Sana, who graduated in 2022.
• The Ghost: Several characters are mentioned in bios or in passing, but don't yet appear in person.
  • The CEO of Hololive Productions is referred to as simply 'The CEO' in full, yet doesn't ever seem to show his face. It is implied that he is Holograph's counterpart of real life CEO of COVER Corperation: YAGOO.
  • Luna's butler, who is apparently the only adult figure in her life providing her guidance besides her friends, does not appear in person.
• The Stinger: Myth, Plasmagic Seasons and Stardust Song all end with a teaser hinting at the events of Resistance, a feat made possible by the fact that all three arcs happen chronologically around the same time as eachother.
• The Power of Friendship: Come on now. Sonic is absolutely no stranger to this theme even to the point of it being the main focus of some games' plots, and Hololive is all about spreading love, happiness and all that good stuff around the world. In-universe, Aura Energy multiplies by the power of bonds and gains a positive charge, while isolation and hate does the same while pushing it towards a negative charge - effectively turning friendship and loneliness into exploitable weapons for good and evil both (See The Power of Hate below).
  We took our hands towards our brightest dreams
  Giving all, we are now a team!
  I’ll blow your mind! Now take my hand!
  Let’s show this world our dreamland!
  — Shiny Smily Story, Kiryu Coco ver.
• Time Master: When using his Aura-powered golden bracelet or his Shining Sonic transformation, Sonic gains the ability to control time to a certain degree. He can pause, rewind or slow time for a precious few seconds using his bracelet whereas his Shining Form is limited only by Sonic's imagination and energy reserves. Also applies to:
  • Amelia the Dog, a time traveler who also uses an Aura-based artifact in the form of her pocket watch which allows her to properly travel through time as far as she likes.
  • Entropy, a cosmic monster born from the straightforwardly-named Time Eater of the Sonic series regenerating from death by snacking on local Hololive void monsters The Ancient Ones.
• Weird Crossover: No but, really. Sonic the Hedgehog, a shounen-inspired video game series about anthropomorphic animals fighting a mad scientist and Hololive, a collective of virtual idol live-streamers? The longer this AU has been in production however, the less outlandish the premise has become. SEGA and Hololive have collaborated multiple times now, Korone Inugami has started her journey into the Sonic series and been contacted by Sonic^note 's voice actor using a Live2D model himself live on stream! With Korone and Sonic getting chummier by the day, it's become something of a recurring gag behind the scenes that Sonic Holograph is Canon.
  • In August of 2022, it was announced that the upcoming Sonic Frontiers would have a (currently) Japan-exclusive DLC pack themed around Korone, complete with: A replacement set of sound-effects made from her voice, swapping out NPCs for the Koronesuki (representative creatures of her fanbase) and even a new outfit for Sonic themed after Korone's own clothes. The trope edges further and further towards being averted.
