It was midday on Mobius as Sonic and Sally were seen doing patrol for any activity from Robotnik or his minions. Though Robotropolis was quiet, with only the sound of the factories being any indication that it was still in operation.

Sonic: "Boy, Robotnik sure is quiet today."

Sally: "Yes and that ended well for us last time too."

Sonic: "We got to enjoy our picnic, so I'm not complaining."

Sally: "Still, we probably shouldn't drop our guard again."

As Sally finishes saying this, a portal open in front of the two, with Sonic recognizing the portal.

Sonic: "It's one of those portals to that weird area that I tripped into last time!"

Sally: "The one where you claimed to have found a Mobius similar to our's but completely backwards?"

Sonic: "And with one nasty hedgehog."

As Sonic stands between Sally and the portal, a figure walks out. It was another hedgehog, no less a blue one like Sonic herself, with a lot of the same features down to the same shoes. The only difference was the pudgier belly and being clearly a boy hedgehog. In fact, it looked like Anti-Sonic.

Other Sonic: "Whoa. I've been to three Mobiuses so far, but this one looks downright identical to my Mobius the most."

This other Sonic is quickly kicked by this Mobius' Sonic, knocking him off his feet before he flips back on them, landing as he glared at his female counterpart.

(For the sake of you all, I will refer to this story's Sonic as "FemSonic" and Archie's original Sonic as "Sonic Prime".)

Sonic Prime: "Whoa! Hey!"

FemSonic: "Don't 'hey' me! I don't know why you're here, but I am not dealing with a creep like you!"

Sonic Prime dodges another kick, retaliating with a jumping punch, though he does hold back a bit since he wasn't here to fight. FemSonic though wasn't going to hold back, grabbing Sonic Prime's arm and tossing across the area.

Sonic Prime: "Look, lady me! I don't know what your beef is, but I'm not here to fight!"

FemSonic: "Then leave! Even without those shades and leather jacket, I know it's you!"

As Sonic Prime dodges more of FemSonic's attacks, he realizes just what she meant. He jumps back to get some distance and calls for a time-out.

Sonic Prime: "Hold on! I know who you're talking about; I'm not him!"

FemSonic: "Oh yeah? Prove it then."

Sonic Prime: "I, Sonic the Hedgehog, promise to fight for freedom, justice, and good manners…"

This caused Fem Sonic to pause and calm down as she continues to quote the Freedom Fighters' oath herself.

FemSonic: "...and oppose all evil tyrants…"

Both Sonics: "Especially those with cheap red costumes and pointy heads!"

Sally: "Whoa… Word for word. No evil alternate universe Sonic would have an oath like that."

Sonic Prime: "Thanks, Sal… er… Other universe Sal. I don't know what Anti-Sonic did to you, but for you to act out so badly, it had to be way past uncool."

FemSonic: "Way, way past uncool… So who are you then?"

Sonic Prime: "I'm Sonic the Hedgehog, but from the Prime Universe. To put it bluntly, I'm the original Sonic that's at the center of all other Sonics. I found out about these other universes after I had a run in with the dork in shades, Anti-Sonic, where he explained the whole shebang. Come today, another Sonic appears out of the portal leading to the Cosmic Interstate, saying that an even worse Robotnik than the one you or I know of is planning to take over the entire multiverse! So me and that other Sonic - Cybo-Sonic of the Cyborg Freedom Fighters - hatched a plan to find other Sonics who could help us beat that Robotnik."

FemSonic: "Tch. Of course it's Robuttnik causing trouble… And regardless if it's your Robotnik, my Robotnik, or someone else's, I say it's only fair we show ol' blubber butt how we play."

Sally: "So you're going with him, Sonic?"

FemSonic: "Course. Got to send a message to all Robotniks that any and every Sonic means business."

Sonic Prime: "Took the words right out of my mouth, Girl Sonic. Gotta say though… Didn't think I'd pull off the girl look so well."

FemSonic: "Sorry, boy me. I ain't interested in dating even myself."

The Sonics couldn't help but chuckle at that as FemSonic leaves with Prime Sonic, being escorted to Mobius Prime, where she greets her fellow Sonics, who had also been dragged out of their universe due to the warning of a new threat.

Some time passed as Sonic and Cybo-Sonic returned with a large collection of Sonics from multiple universes. Sonic gave a speech about how they would defeat this new Robotnik, but that very Robotnik soon appeared - Robo-Robotnik had sent his army of Shadowbots to invade, but Robotnik Prime soon showed up with his own Swatbots. Sonic Prime and Robotnik Prime soon teamed up, with Robotnik Prime stating that Robo-Robotnik was likely after the Giant's Hand. FemSonic joined the other Sonics into the Cosmic Interstate in order to find this strange relic, soon finding the Neutral Zone and Giant's Hand in it. However, Anti-Sonic soon showed up and distracted the good Sonics long enough for Robo-Robotnik to snatch the hand right from under their noses. Armed with the newly christened Giant Borg, Robo-Robotnik began his reign of terror; but thanks to Sonic's quick thinking and inspiration, the Sonics toppled the Giant Borg and destroyed it, along with Robo-Robotnik. With that, the day was saved…

After the battle with the Giant Borg, FemSonic was given a piece of the Borg as a trophy of this adventure, but before leaving, she walked up to Sonic Prime.

FemSonic: "Yo, Sonic Prime!"

Sonic Prime: "Yo. What's wrong?"

FemSonic: "Nothing. I just wanted to apologize for earlier. Guess I got a bit too jumpy for my own good."

Sonic Prime: "Ah, we've all been there. Rush in, think later. Right?"

The two Sonics just laughed at that.

Sonic Prime: "In any case, next time I'm around, how about a race to see who's faster?"

FemSonic: "You're on!"

With a handshake, FemSonic takes her Borg piece and hops through the Cosmic Interstate, starting her way back to her universe. But not before having another run in with Anti-Sonic.

Anti-Sonic: "Well, well. If it ain't the broad who caused me some undue trouble. You still owes me a new set of shades after you broke mine."

Sonic: "Screw off, dork. I owes ya nothin' but a free butt kicking."

Anti-Sonic: "Yeah? How about I turn ya blue and black then!?"

Anti-Sonic rushes at Sonic, aiming to clobber her. Sonic puts down her Borg piece and ducks under Anti-Sonic's punch, then flip kicks upwards, kicking him hard enough to send him bouncing right back into his Mobius, solving that issue right away.

Sonic: "...What a dork…"

With that brief bit of conflict done with, Sonic ran back to her home in her Mobius, placing the Borg piece on her wall as a trophy and a reminder of her adventure in Mobius Prime. A fun adventure to remember to be sure…
