Cosmic Heart Zone

(Sonic Alternate Universe Ask Blog) A look at a What if scenario where Tails and Cosmo first met in the main series/canon games as far back as the first Sonic Adventure! Chris Thorndyke and the Metarex do not exist in this AU's events. Though other characters and/or locations of Sonic X may be adapted in. However you can direct Sonic X related comments or questions to Extra Miles.

COSMIC HEART ZONE TIMELINE INDEX

(If you'd like to view the blog in order of which posts came first. I recommend viewing on Archive Of Our Own)

This is just an index that'll list each game within the timeframe of this Alternate Universe starting with Sonic Adventure all to the way to the most recent Sonic game. This will be updated as more asks that refer to what happened in each game's story and/or appearance by Cosmo are included. Note that this isn't 100% a checklist, as a game can be covered multiple times depending on the ask.

Sonic Adventure - How They Met, Confusmo, Big Friendly Neighbor, Cosmo's Tree Form, Asking the Frog

Sonic Adventure 2 - Cosmo the Hero, Cosmo's Hero, The Asteroideae, Shadow's Visit, Maria Robotnik

(Note: Although Smash is listed, this does not mean Cosmo somehow got playable in the CHZ timeline. It's staying Sonic only as it is for us in official Smash games. This is more so for crossover references. If you want to hear about Cosmo in a fighting game. Ask about Sonic Battle instead!)

(Updates that don't necessarily have any category they belong to, whether by game or short series) - Pilot, Cosmo's Playlist, Manic the Hedgehog, Crying Gushers, Cosmo's Bloom Day, Cosmic the Hedgehog, Tails' Birthday Traditions, Utensils & Favorite Colors, Boom Cosmo & Coral the Sea Dryad, Tails, I Want You To Shoot Me...

MISC. CATEGORIES

Chao - (Tagged posts related to Chao and/or the Chao garden)

CHZ Seedrian lore - (Tagged posts that either expand on what little lore there was from Sonic X, and/or entirely original to CHZ)

A Royal Call - (Tagged posts related to a voice call with Cosmo's Sister, Galaxina!)

Team Rose Takeover - (Tagged posts where Amy, Cream, and Cosmo answered questions together as a team!)

Cosmic Rush - (A cross-dimensional story celebrating the 20th anniversary of Cosmo!)

Mom, Did Dad Want To...? - (CHZ Cosmo has a serious talk with her mother as an immediate aftermath of what she heard from the X Universe while she was stuck there in Cosmic Rush)

Xtra Miles - (Spinoff of the CHZ TailsTube style, but in the Sonic X Universe! Ask the original Tails and Cosmo we knew and loved from Sonic X!)

These games below can still be asked about but may be difficult for one reason or another

Sonic Shuffle - Lumina Flowlight and Void (Cosmo would likely be at most an extra character ala Big and Gamma and not in the story. As amusing it may be to point out that Lumina and Void have similar design similarities to Cosmo) Sonic Pinball Party - (Can... we really expect much from a Pinball game for Cosmo to be involved in?) Sonic 06 - (The game retconned itself, even if we did cover what she might have done in the game. She won't remember it) Sonic Rivals - (I guess maybe at most a minor role in the 2nd game since Tails gets involved? Otherwise I'm not sure Cosmo would fit a game about rivals necessarily) Sonic Chronicles - (Had a cliffhanger ending that will never ever be resolved. And I'm sure as heck not going to be able to resolve it myself! Cosmo's existence as a canon character isn't just going to create a Sonic Chronicles 2 out of nowhere) Most games set before Sonic Adventure 1* - Tails Bullies, Kuku Empire and the Witchcarters (That includes Sonic 4, Mania, and Superstars)

*Though it just could cover what Tails said when telling Cosmo of his past adventures

[cosmicheartzone]

Tails: Now to buff up security of the show to make sure nothing like that happens ever again. The rogues are one thing, but imagine if Eggman tried something like that as well...

Oh and apologies for people who actually had legit questions for the Rogues while they were here. Maybe some point later we can answer what we know about the rogues. But we may be in the dark about them as you all are. Jet and Wave aren't exactly well known for sharing stories other then race victories or about their extreme gear... and they'd probably make fun of you for caring about anything else too.

[cosmicheartzone]

((Been playing quite a bit of the new Tomodachi Life. Which conveniently also includes rejections and miis being angry at eachother ha

Though on another note, I definitely underestimated how long this one would take. Remember when I said this might be shorter then the Sage one? Yeah that didn't turn out to be the case, oof. Apologies if maybe the Arle Nadja festival response gets delayed cause of this))

[cosmicheartzone]

((Jet sprites by Gabriel Frag, Wave sprites by Zig Sonar, and Storm sprites by Cylent Nite))

((What started as a bit of Storm fearing Amy's rage and/or hammer after Zero Gravity seems like in Crossworlds it has developed a bit. Amy noticing Storm staring at her, as well as Storm maybe having a slip of the tongue there when he said admiring, the other interaction showing that he doesn't want to hurt Amy with the 'I have to hurt you, cause I'm... like... strong and stuff' sounding like a a poor attempt at a flirt. At least that's my interpretation of their interactions in Crossworlds))

[cosmicheartzone]

((Jet sprites by Gabriel Frag, Wave sprites by Zig Sonar, and Storm sprites by Cylent Nite))

((Told ya at least someone was going to get here fast!))

[cosmicheartzone]

((Jet sprites by Gabriel Frag, Wave sprites by Zig Sonar, and Storm sprites by Cylent Nite))

Cosmo: *whispering to Tails* Well… as much as I hate they took over our show… I’m at least curious who Storm has a crush on…

Tails: *whispering to Cosmo* That’s exactly how they get you… it’s like clickbait… but… I would be lying if I said I wasn’t interested in finding out too…

[cosmicheartzone]

((Jet sprites by Gabriel Frag, Wave sprites by Zig Sonar, and Storm sprites by Cylent Nite))

Jet: Nice of you to even pick a nice green screen just for my arrival!

Cosmo: …That’s because it happens to be MY screen.

((Another guest appearance... although very much uninvited. And unlike Sage's, there's no ambiguity of intentions here. The Babylons are jerks and bullies, and Crossworlds indicate they haven't changed much from that depiction. So Tails and Cosmo are far from pleased by them forcing their way into the show.

This does mean you might want to be quick again with any asks for the Babylon Rogues, as there's a chance this ends up even shorter then the Sage one. You know at least SOMEONE is on their way to help Tails and Cosmo at this very moment. And you know how fast most characters can run in this franchise. They may not be the angry birds, but they're birds that make Tails and Cosmo angry...))

[cosmicheartzone]

((Entirely Pac-Man themed due to the inclusion of the Ghost Gang! Had help for writing this one from a friendly Pac-Man fan who goes by SuperTheDuper. Thanks for the help, Super!

Most of the ghost interactions refer to their behavior in the maze, although for Inky's it's a reference to the Wormwood boss in Pac Man World 2 and Re-Pac 2))

[cosmicheartzone]

Cosmo: This took place before the Crossworlds Grand Prix started, as it was the first time Sage met the Chaotix. Which while I'm on the subject... I did try to have a talk with Sage during this to learn of her intentions sooner, but Infinite's sudden return and attack got in the way.

[cosmicheartzone]

((Next time on Xtra Miles, Chris Thorndyke's response to the letter!))

[cosmicheartzone]

((Water gun sprite is slightly edited from a custom Splatoon Inklings sprite sheet made by Toni/Bot-Chan))

((Silly thing for April Fools! Turning words that haunt many Tailsmo fans who've watched the Japanese Sub of the final episodes of Sonic X and recontextualizing it into something more wholesome.

Important note I must mention is I think timeline-wise this could have only happened somewhere between Sonic Adventure 2 and before the events of Shadow 05. With Cosmo experiencing summer in the Mystic Ruins for the first time. I'm not even sure Tails and Cosmo are a couple at this point yet, as I think it could work if they were only friends at this point just as well as if they were dating.

If this were after Cosmic Rush, they'd be aware how er... of bad taste this conversation would be haha))

[cosmicheartzone]

((Megaman 9 lab background ripped by Rabbid4240, Plant Man and Wily's castle ripped by MisterMike, Megaman sprites, and the custom Tails and Cosmo sprites kindly provided with permission by KeiyuStyleKai! Thank you so much Keiyu!))

Tails: I'll go talk to Dr. Light and see if we can create 'Plant Girl' together!

((The comic's punchline based on the How It Should Have Ended channel's Star Wars running gag of every time Anakin/Darth Vader finds out he has a child or he's going to be a father))

[cosmicheartzone]

((Some Fanart of the CHZ Chao courteously drawn by Tipsyra1d3n! Who himself has quite the interesting Tailsmo AU of his very own called Chaos Bloom. Most of Tipsy's finished works can currently only be found sporadically in either or both the Tails and Cosmo reddits (Probably just type in Chaos Bloom in the search bar for either of the reddit pages)

Thank you so much Tipsy for the cuteness overload!))

[cosmicheartzone]

((Some notes on this one I wanted to cover. I don't know too much about Persona outside of what I could see in Super Smash Bros. Ultimate or in any osmosis with friends who have played Persona 5. So Joker's was going to be a little difficult without help, but luckily the Chaotix Casefiles came out at a good time (And thanks to the Sage episode, confirming it took place before Crossworlds) to reference here.

And if I didn't know much about Persona, I know even less about Yakuza. But Ichiban's obsession with Dragon Quest provided a quirk I could cover. The Rose Princess is from Dragon Quest X, which seemed to be a Japan only MMO. In other words only a die hard Dragon Quest fan would even be aware of in all likelihood.

Spongebob and NiGHTS were certainly a little easier though based on seeing much of the earlier seasons of the show and how NiGHTS have met Cosmo in previous racing occasions))

[cosmicheartzone]

Cosmo: There’s also some things Espio said while he and Vector recapped to us about what happened prior to our involvement in the battle with Infinite during a case prior to the Crossworlds Grand Prix. It sounded like Rouge flirted with Espio many times over the course of those events.

Tails: Either Rouge has given up on Knuckles, exploring other options in case she can’t steal Knuckles’ heart any more than she could the Master Emerald, or she’s purposefully hitting on some of his friends in hopes of baiting him into jealousy…

Cosmo: I hope she hasn’t given up. I kinda liked the thought of that triple date idea Amy brought up during our Team Rose Takeover

[cosmicheartzone]

Cosmo: I've heard the Babylon Rogues complained that their AI Racers weren't using Extreme Gears. They do probably have a point though, since that's what they're practically known for. If I ever saw say Jet driving a car for a race, I'd wonder if that's even Jet! Mimic's gone, but who knows if maybe there's others like him

Happy 21st, Cosmo fans! (Bonus for Steam/PC Crossworlds players below)

Hey guys, today is March 12th. Thus it's the 21st anniversary of the first time Cosmo ever debuted on television (Specifically in France). While I don't have as much of a big thing for CHZ for it compared to starting Cosmic Rush. This should still be special enough since it just happened to get complete at around this time.

Months back I made a request for Sonic X music over any DLC Album tracks in the game and a kind modder named Elfy/FriedYams was nice enough to fulfill it. Even going the extra mile of giving players full choice of what DLC albums they want to replace the songs with.

(Click the image or this sentence to go to the GameBanana download page!)

The collection includes:

Sonic Drive

Gotta Go Fast (NateWantsToBattle cover for the Final Lap)

Mi-Ra-Ai

T.O.P.

The Shining Road

As well as a bonus collection that includes

Kotoba Ni Dekinai

Midori No Hibi

Natsu No Hi

There's also an optional choice to include a Shining Road snippet over Sage's Grand Prix victory theme that's meant to complement MurfyDaMurfi's Cosmo alpha build mod (Keep in mind two things however: This also replaces regular Sage's victory theme and if you have any other victory theme mods, menu, or monster truck sound mods it will likely conflict. Unless you can manually mod in the victory theme to be packed in with those, you'll have to mind that this the only thing it changes is the victory theme for Sage)

Honestly this whole thing was sort of meant to complement the currently still in development Cosmo mod. It's still not finished (Alpha build's still playable though) but the hope is that by the end of the year it will be in a state that Murfy is comfortable letting it be showed off on Youtube and other places. At least whenever that time comes, the music will be there to go with it!
