Sonia pours out her distress to Mindy

Info dump ahead.

Okay! So after the Council of the Four defeat Robotnik and take back the land, Sonic disappears. Sonia and Manic try to find him, while their mother tries to rebuild her kingdom. (Sonic is just chasing down Eggman, but they never seem to catch up.)

Over two weeks ago I made this post

And here it is.

Sonic gets attacked by new eggman robots that he cannot damage in any way, and he gets separated from all his friends.

His only leads are:

The robots are similar to the ones from Starfall Islands

A gut feeling that Sage might be involved

A mysterious medallion he found after nearly drowning to death appears to reveal a map to a location he's never been in

Creative process beneath the "read more"

So, Sonic Underground came out in between the JP and US releases of Sonic Adventure, meaning it is completely divorced from moder Sonic media.

I always wanted to make a post-frontiers story that didn't involve some form of Evil Sonic or dead/missing Sonic.

I also noticed how few appearances Sonic makes in my usual stories, so I thought him as a focus would have been fun and a change of pace.

I watched Sonic Underground a lot as a kid, and I have held to this day that the most interesting thing that show did was giving Sonic two siblings to bounce off of that are the same age as him.

Now for the actual fic:

Most of my fics are LARP'd / music daydreamed before I write them down, which is why most of them are based on songs, and this one is... Actually an exception.

The post linked at the top is essentially how I came up with if this one. "What if Sonic Underground comes after Frontiers", and that's it.

That means that Sonic, Manic and Sonia have been apart for many years after their childhoods and that influenced how I wrote them.

I wrote Manic as a sort of community pillar vibe because of his scrappy upbringing evolving into a sense of community and activism. It also complemented with the decision to make a cymbal shield his main weapon of choice which does appear on the show. Him always breaking silences will be a running gag, don't you worry.

Sonia is a little more stick in the mud, mostly because right now she's in "business" mode, and I do plan to have her relax a bit as they make progress in saving the world. Also, the keyboard gun is not my invention, it's in the show, and that influenced her personality in this first chapter for sure.

Sonic is Sonic. Self explanatory in my opinion. The main changes from canon I suppose is that he's a lot more awkward around the other triplets, which just came about naturally, the fact that he's careful now (I imagine because Tails eventually gave him an earful about his attitude in Starfall Islands). Changing the laser guitar into a guitar sword is my firm belief that's how they'd do it if Underground had come out after Sonic and the Black Knight. It also helps him stand out from Sonia who also shoots lasers.

The most important thing I avoided was making the triplets eager to call eachother siblings. There's no way they get there quickly, they've lived their own lives for far too long. Manic being excited about it probably says something about his character.

The ending of this chapter comes from me realizing the seven chaos emeralds aren't a thing in Sonic Underground, and wanting to incorporate that in some way.

Also Infinite! What's he doing here? Not too sure.

And that's the gist of it

Who wants a Sonic Underground Swapped AU

I’ve been a huge fan of Undertale for a pretty long time. And one of my favorite things about it was the concept of “different timelines/universes” that so many fans started to make. I know AUs have been around for a long time, longer than Undertale, but it was because of Undertale that I started thinking of AU ideas. 

Case in point: A Sonic Underground AU where all the characters' roles and personalities are swapped. 

A…Sonic Underswap, if you will. (I am going to hell)

The idea smacked me last night when I thought “...hmm. Wouldn’t it be funny to imagine a Manic who grew up in Sonia’s shoes?” It then formed into wondering “Who would switch with who?” So… I will jot down what I think a Sonic Underground Swap would be like.

And, while I would pull the whole “the triplets are evil” idea…but where’s the fun in that?! (...aside from a lot of fun to begin with). This is playing with the idea that MOST of the characters are still the same when it comes to their placement in the story. 

There is one HUGE exception:

Obviously, Aleena and Robotnik would HAVE to swap places. This would mean Aleena becomes the “tyrant ruining Mobius” while Robotnik is hiding away, hoping to one day take Aleena down. 

So the story would go like this:

Fearful over the thought that her newborn children could overthrow her, Aleena abandons them shortly after birth in hopes of ruling. Even if she is a really bad leader. Brushing off the struggles of her people as she feels they aren’t worth her time. Only those who pay the outrageous tax have her attention, and they never really have any struggles, to begin with.

Robotnik, being an outsider notices just how horrible she is running Mobius and plots to take her down. With the help of Athair’s future visions and elderly wisdom, he realizes that her children are alive and are destined to fix what their mother has caused.

However, Aleena didn’t deal with her children as well as she had expected, and they were raised by three different families.

As mentioned, Manic would be raised in the higher class, with Sir Farrell as his father. Raised to use and abuse the lower class and how much they need to rely on the upper class to stay safe, and he isn’t afraid to admit that. But, hey, at least he has a close friendship with [_____], though even that is stripped away when he was exiled due to Aleena realizing her children were a risk. Now he feels like an outcast when he joins up with Sonia and Sonic, both lower class and slightly spiteful over Manic’s upbringing. 

But he does know how the upper class works, and what makes them tick.

Sonia, meanwhile, takes Sonic’s role. 

After all, if she didn’t fill this tier, Sonic wouldn’t have changed. And, honestly, I feel the idea that Manic being raised high class and Sonia fighting with the Rebels (the Resistance) gives better story ideas over Sonic being raised high class and Sonia being poor.

Anywho, Sonia was raised by Windemere, a high-status member of the Anti-Royal Movement, better known as the Rebels. She was adopted by Windermere after her “original” family was killed during a raid. Since then she has been fighting for what she felt was right. She is heartbroken during a raid when she finds out that Windermere was caught and, later, was found out to have been hiding one of Aleena’s children. 

She is well known by the Rebels. 

Sonic was found by Chuck, who’s been struggling hard since Aleena’s rules made it harder and harder for the lower class to survive. Everything has gotten so expensive (mood), and he wasn’t going to rescue the infant, but he couldn’t abandon a life in need. Sonic grew up knowing that life is harsh and mean. Don’t trust anyone but yourself, ESPECIALLY the higher class. That makes him and Manic not get along really…at all. 

Sonic is still the fastest, and his speed helps with snatching up food and money. But mostly food. 

Aleena is warned by Athiar about her eventual demise, causing her to stress out and hire Dingo and Sleet, famous mercenaries who can easily find and…silence almost any targets. For the right price, of course.  (...I think you are seeing where this is going)

Though he relies more on his brawn than his brain, Dingo is still the leader of the duo, always more focused on his work, and less focused on anything else. However, he has to always remind himself to keep a close eye on his absent-minded partner, Sleet, and he is starting to wonder if the wolf would even notice if he left him mesmerized by something. It doesn’t help that Aleena’s influence is beginning to rub off on him. Why worry about a mobian that causes him more trouble than he’s worth?

Sleet’s mind’s in the right place. He’s smart, and when he’s able to focus on the job, he can be a real threat. Too bad he’s easily distracted and is amazed by everything and anything and will often leave Dingo to do most of the heavy lifting. It doesn’t help that Sleet thinks that Manic is super cool and admires being JUST like him one day. He never realizes that his constant admiring is getting on Dingo’s nerves, though. It’s always work work work with that canine. Can’t he stop and enjoy the moment once in a while?

All his life, Cyrus was raised to believe that everything Queen Aleena said was law and that those below him were just obstacles in his way. But when his long-time friend, Manic, was found to be the Queen’s son and she wanted him gone before he and his siblings could overthrow her, Cyrus finds himself in a pickle. Maybe, if Manic accepts that Aleena is the true Queen and promises to not try and defy her, he’d get his friend back. Why even worry about the others when he had everything he needed if he just behaved? 

Knowing Sonia from the Rebels Group made Bartleby a target for manipulation for Aleena, trying to trick the mink into luring the Rebels out and punishing them for all their wrongdoings, all to protect what remains of his family’s history. But once he realizes that the lives of innocent mobians would be at stake, he quickly breaks away from her control and vows to help the Rebels in any way he can. His love for the arts helps him create things, though they seem to be more dangerous than helpful. It’s the thought that counts, right?

The other prevalent member of the Rebels is Knuckles. Cunning and decently strong to boot, he makes good support for the group. He also knows a bit about nature, so that’s a plus. Early on, he was captured by Aleena, who attempted to learn a thing or two about the growing Rebels, but the triplets quickly saved him when Sonia realized he was in danger, as the two knew each other from childhood. 

Under the watchful eyes of “Delphius” (The Oracle isn’t “the Oracle”, but is replacing Athiar), Trevor is destined to watch over the Chaos Emerald resting within the Floating Islands. Good with the few mechanical items he can find littering the Island, he became quite a handyman, making small weapons and other things to keep the Emerald, and the Island, safe.

If it isn’t obvious, Cyrus and Bartleby swap while Knuckles and Trevor swap. 

It was…hard trying to figure out who would take Knuckles’ place, as he is kind of…REALLY strongly tied to the Emeralds. But, Trevor has as much character as Knuckles does in the show, so it fits. 

I also find it funny that the two characters that have some sort of relationship with Sonia…STILL have relations with Sonia, just differently. (Seeing as Bartleby and Knuckles take Cyrus and Trevor’s place, who were friends of Sonic originally).

The Oracle (or just “Delphius”) and Athiar also switch places. The Oracle was a strong contender for the one switching with Robotnik, but…Athiar makes more sense in the long term. Both are old. Most likely DEAD already. One is cryptic while the other is a bit of a fearful hermit. 

So, yeah. There we go. There are other characters in Underground, and they’d all switch around as well, but I’m gonna leave this here for now with the more important characters.

A small collection of my Sonic Underground AU u//v//u hweehee

[wardaykgerblin]

AU where Shadow and Silver get swapped with Sonia and Manic. They all mostly keep their personalities with a few altered things because of their new pasts.

Sonic and everyone else stay the same.

"don't even get me started with Tails not being in Sonic Underground!"

get started, the relationship between sonics blood siblings and tails would have been so interesting, especially if he knew tails first. they could've done so much with his manic being envious of tails and sonics bond and tails feeling like sonic doesn't need him anymore.

I have honestly thought about this kind of thing A LOT. From what I know, Sonic had another adopted family before being taken in by Chuck. What if they were Tails' parents, and had him a few years after taking in Sonic. Then Chuck would raise both of them until the triplets met up, and Tails joins them.

With your scenario, I actually thought of something like that, but the other way around. Manic and Tails getting into an argument one day, only for Manic to shout that Tails isn't even Sonic's real brother. Hurt by those words, Tails runs away. Sonia and Sonic would get mad at Manic for this, and search for the kit. Sonic would even point out Tails lost his parents to Robotnik because of him, so he owes it to fox to be the family he never knew. By the end of it, Manic and Tails would make up, and begin to treat each other better.

I also love the idea of the triplets making Tails his own medallion to match theirs. ^_^
