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. The X Universe's own version of TailsTube. https://www.tumblr.com/cosmicheartzone/tagged/Xtra%20Miles Most sprites will not be my own.

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

for a list of questions that have already been answered. Go here)

This is just an index that'll list each game within the timeframe of this Alternate Universe starting with Sonic Adventure all 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.

Go here for the full index for all seasons of CHZ!

Also a reminder, don't be shy about your asks! Send as many as you wish, the more the merrier as Eggman might say. Not only does it give me more ideas to pick from, but it helps motivate me to make more CHZ posts sooner when genuine asks are sent to me. And also remember that we have both the CHZ Tails and Cosmo, and Xtra Miles for the Tails and Cosmo from the X Universe as options!

[cosmicheartzone]

Cosmo: …Oh! Before we forget, Tails… what about those alternate universe versions of you, Knuckles, and Amy. Nine, Dread, and Rusty Rose I mean?

Tails: Oh that’s right, we probably could at least try and give them a call but I don’t quite know them enough if they’d answer or not. It’ll all depend on the questions asked.

((This is a mixup to the guest formula that's kinda been made necessary by many factors outside of my control. One of example of which being that fresh asks have dried up for it feels like months now so it's necessary to change up how to approach other characters appearing other then Tails and Cosmo. With the likelihood of them being there to answer depending on how close they are with Tails and Cosmo and/or the character's availability (And for some, whether or not Tails and Cosmo would even allow them to speak on the show)

For what it's worth I have wanted for a while that at least Sonic, Knuckles, and/or Amy could appear at any time without technically being guest stars anyway. But never really got to make that clear. So may as well open the floodgates to a majority of the playable Sonic cast of Crossworlds while I'm at it))

Thought I'd let you know that I've updated the timeline index to go to a google doc. Turns out there is a hard limit of how many links you can put into a single Tumblr post. So having it all on a single doc and also separated by 'seasons' would be more convenient. As always the AO3 version of CHZ is best if you want to see all posts in the order that they came out in as I know going back to the first page of a tumblr page isn't the most convenient way of seeing things in order.

And I'll also put some further encouragement on the last part for more asks. I have an archive of most if not all unanswered questions but it'd be nice to have some more fresh asks sent my way every now and then that reflect more recent happenings in Sonic news and such. Or if you want a follow-up on previous CHZ posts. Anything to have a little more community input with the blog.

Tails: The younger Sonic has already seen friends and villains he wasn't supposed to yet. And there hasn’t been any strange repercussions from that alone. Maybe it’s a case where this younger Sonic is more like Blaze now in a way, just from a world where some of the major events in our timeline still have yet to pass but he can still crossover every now and then. Thus making him more so from a parallel timeline then the actual younger version of our timeline's Sonic.

If that's the case, I don’t know if there will be anything serious that comes of this Sonic knowing more about the future then he’s supposed to in his hypothetical timeline. But hopefully it turns out alright.

((Happy 35th anniversary week Sonic fans!))

[cosmicheartzone]

((Happy pride month everyone! Featuring the fan favorite lesbians. Most DLC characters still only get one interaction, but wanted to make a special exception for any bonus Sonic characters that make it in before the end of Crossworlds’ run. Maybe some day soon we’ll see Surge show up?

Also AiAi might look small, but he’s canonically married in the Monkey Ball series))

[cosmicheartzone]

Tails: Of course there was also the time our universe’s Eggman also somehow pulled out this sort of game. During a revisit to Chemical Plant when I was younger.

((The 2nd frame mostly alludes to a certain chapter of Cosmic Rush, where CHZ Tails faced Scratch, Grounder, and AOSTH's Robotnik in a game of Mean Bean Machine

But yes, the chapter also noted that Tails and Cosmo have played Puyo Puyo on handheld consoles before. So they'll certainly give a warm welcome Arle to the competition!))

[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.

((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]

((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))

((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.

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

((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))

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