Sally explains that the time of Xorda's attack is the same as the Days of Fury, which created most of the current inhabitants of Mobius. Locke, calling from Angel Island, confirms that the Brotherhood picked up that fact as well. Rotor has finished his device and is giving it to King Max to talk to Xorda. Sally convinces her dad to let her do it instead. Sally tells Xorda that the humans are no longer the dominant species of the planet, but Xorda already knew. They say that the Mobians have a lot of human DNA so they're going to destory the planet anyway. They cut off Sally about to protest and back at the castle, Robotnik cuts in (knocking the Brotherhood's line off). Robotnik has a robot called "Giga-bot Prime" that he thinks can beat Xorda. The "problem" is that it's too big and only Sonic can power it with his speed. Sonic is ready to go, but King Max says to wait. King Max says that unless Robotnik gives control of half his territory (Robotnik controls 99% of the planet supposedly) to the Kingdom of Acorn that Sonic isn't going. After a little hesitation (with King Max basically saying either accept it or die), Robotnik agrees and cuts off.

Meanwhile, in the cosmos, Knuckles senses the destruction of Mobius and confronts Aurora. He asks her if they can win without him, but she won't answer. Then he asks her if what she said about only having one life is true. Before she can (or cannot) answer, we turn back to Knothole...

Sally is addressing everyone in Knothole about all the Freedom Fighter groups around Mobius being on standby while Sonic has a mission to take care of Xorda. In the castle, King Max is talking with Locke, who's surprised Robotnik agreed with Max's terms. Max said desperation does wonders. Locke agrees with that since on the island the echidnas ("straight" or Legionnaire) and the dingoes are banding together for once. King Max promises to keep Locke updated on what Sonic's doing. In Knothole, just as Sonic is about to leave, Sally says that she wants to go with him and he takes her along.

In Megaopolis, Robotnik takes them to the robot. Sonic starts powering the robot as they (he & Sal are both inside) head out into the city. Xorda notice the robot coming to attack them so they fire a laser at it, but the Giga-bot's shields hold. Giga-bot punches Xorda's ship, knocking it off balance so Xorda retreats higher into the air.

Figuring Xorda had enough, Sal & Sonic celebrate. Their happiness is cut short as suddenly metal clamps appear and bind Sonic to Giga-bot. Robotnik claims that since Xorda is gone, he doesn't have to keep his promise and now he has Sonic to power his greatest weapon. Just then, Xorda sends out another telepathic message to everyone as they fire something out of their ship into a snowy part of Mobius. It's called the Quantum Dial and once its arm makes a complete circle, it will create a black hole that will take in the entire galaxy. With that, Xorda takes its leave since they don't plan on being sucked into the black hole. Robotnik isn't scared as he figures he'll just use Giga-bot to destroy the Dial. Elsewhere on the planet, everyone is beginning to leave their stations to head for the Dial as well.

Back to Knuckles & Aurora. Knuckles calls Aurora out on her lie about no one being able to live again. Athair pops in now and tells Knuckles that Knux is considered worthy for a second life. Knuckles says that he's going back then and asks how does he get there. Aurora tells Knux that he has a greater purpose and if he leaves that he'll have lost it. She continues to say that they'll die anyway as "that is the pain of existence" and tells Knux not to be foolish or selfish. Knuckles doesn't see how helping everyone on Mobius is selfish and turns to Athair, who tells Knux that the power is inside him but there's no way to know what'll happen to it once he returns to Mobius. Knuckles says that he's willing to risk it and starts glowing green. Aurora wonders how Knux can give up being part of eternity and unlocking secrets of the universe. Athair says, "Weren't you ever sixteen?"

Back to Mobius, Station Square's missiles (among others as is slightly hinted by the wording) can't reach the Dial. All tech weapons fall apart around 50 feet from the Dial. Commander Brass and Tails are conversing and Brass says that they've got to attack head-on. Seeing all who've gathered (the Freedom Fighters--minus Rotor, Big, Froggy, Shadow, Mina, Monkey Khan, Rouge, the Downunda Freedom Fighters, the Wolfpack, Rob & his Krazy Kritters, the Arctic Freedom Fighters, King Max' Royal Guard & Secret Service, the Chaotix--with Charmy, the Echidna Security Team, the Dark Legion, the dingoes, Drago, Snoop, the Fearsome Foursome all get cameos), at Tails' command they all go for the Dial with the goal of stopping it as it has already started moving. Of course, once they charge, the defense system goes live and starts firing, which scatters the group and basically brings the charge to a halt. As Tails saves Fiona, he sees the Giga-bot approaching. Flying over the defense that has kept everyone else far from the Dial, at about 50 feet away, the Giga-bot falls to pieces. Sally & Sonic land on their butts in the snow and while Sally wonders about what happened, she takes some solace in the fact that they're inside the defense perimeter. Sonic calls it a "blessing" and a "curse" due to stopping Robotnik's dreams, but leaving them with no way to stop the Dial. Nicole scans the Dial & sends the info to Rotor in Knothole. Rotor says that if they can create a counter-force to reverse the Dial's arm, the Dial will be destroyed. Sonic figures he could use his speed to do that. Nicole says that would not be a good idea since the Dial would implode and anything in its immediate vicinity would implode--meaning Sonic. Sonic asks if everyone else would be safe and Nicole says "perhaps" but decides to end the discussion on that as she senses something--a quantum wave that'll incinerate anything within a 100 mile radius that'll arrive in 3.5 seconds. Knowing they can't avoid this, they start to say "I love you" but just before it was going to hit--it stops. They wonder how they're alive and the story shifts to the battlefield...

On the battlefield, the laser cannons have just been destroyed. By the Chaotix, Tails & Rouge, a blinding green light appears and finally takes the form of Knuckles (the one responsible for everything of course) as he finally returns. Julie-Su is the first to grab him and Knux is happy to be back himself. But, he cuts the reunion short as he was reading Sonic's mind as he was coming back and knows Sonic will need some help if they're all going to survive. Knux tries to take off, but lands in the snow to Julie & Rouge's (shown) surprise (and Rouge even gets to call him "handsome"). Knuckles realizes then that the price he's paid to come back is losing his extra special powers. To himself he wishes Sonic luck and says "Goodbye."

Back near the Dial, Sonic tells Sally that since the Dial is still active, he has to try his plan. Sally doesn't want him to because he'll die, but Sonic says that they'll all die if he doesn't. With that, they share a hug and kiss goodbye declaring their love. Sonic runs off to save the world "one last time." As everyone sees the Dial implode, he succeeds in doing just that. Tails says, "Sonic..?" and you see a hole where the Dial once stood.

Sally reaches everyone saying that Sonic is "gone" and the news isn't taken very well. Later on, there's a funeral and flags are at half staff in Knothole. At the funeral are Jules, Bernie, Uncle Chuck, the Freedom Fighters, Knuckles, the Chaotix--including Ray (who was not shown at the battle actually), Mina, Shadow, Fiona, Hope, Geoffrey, Hershey, Rosie, Gen. D'Coolette, Dr. Quack & his family, King Max, Queen Alicia, the President of Station Square & his secretary, and Elias & Meg. They're all sad, but someone else is very happy. Robotnik is laughing his head off in Megaopolis as if he's just received the best present in the world. A statue of Sonic is erected in his honor. It says:

"Sonic The Hedgehog
Saved The World
(A Lot)"

We see Sally looking up at the partially destroyed moon in the sky, oblivious to someone peeking into her room and watching her. I'm not totally positive who it is so I'm not going to venture a guess.

The epilogue: "849,000 light years away..." on a moonish-like place, a blue column of light suddenly appears. After it dies out, an unconscious Sonic appears lying on the ground. And the issue ends with "To Be Continued!"
