Mobius, Post-Apocalypse
Setting: An Alternate Universe with aspects from SatAM, Archie-Sonic, and Sega-Sonic.
Premise:
In the year 3236 Robotnik developed a device to rid him of his enemies and take complete control of the planet once and for all. He roboticized himself, then built a "Biological-Energy-Field Disruption Pulse Generator" (or some-such) - a device designed to eliminate all life on Mobius.
The Freedom Fighters caught wind of this plot, and set out to stop him. However, they were too late - Robotnik powered up the device shortly before they arrived, and it activated automatically even as they fought him. Luckily for the Freedom Fighters and those Mobians being held in Robotnik's prison, the Pulse did not build up to deadly effect until some distance away from the device, thus leaving those within or near-to Robotnik's headquarters alive.
The Freedom Fighters destroyed Robotnik's body, but he transfered his mind into the city's computer systems, giving him the power to possess any robot under his command - even Robians.
The Freedom Fighters were forced to flee Robotropolis, but they rescued the prisoners from the Prison first.
...Luckily, Knothole will still serve as a safe haven for a time, as the BEFDPG did not disintegrate life, only render it inert. (It also helps that with so few of them, the living Mobians will not be producing enough body-heat to be detectable to long-distance surveillance.)
...Another unfortunate effect of the Pulse was the disruption of Chaos-Energy Fields. This means that Chaos Emeralds and Power Rings have lost their power, Angel Island has fallen, and all free Robians have lost their free-wills. Furthermore, without Chaos Emeralds, Power Rings cannot be created, and without Power Rings, Robians cannot be freed...
The Mobians must learn how to survive in a dead world, and deal with their loneliness. However, so long as Robotnik reigns, they know they will never be safe... As the last living or free-willed beings, they must protect themselves so they may restore the planet...
Finally, they deactivate all of Robotnik's robots and computers, and erase him from existence. (Use computer Virus masterminded by Nicole? Or use EMP?)
Restoring the planet will be a far greater challenge, however...
(Note: For slightly different effects, could have some sort of "Organic Disintegrator", or something to kill only multi-cellular life. Also, could push it back to an earlier year, as early as 3234.)

Character Profiles (Optional):
Sonic the Hedgehog
Sex: M
Age: 17
Profile: Leader of the Freedom Fighters. Distraught by the loss of his Uncle and by his failure to protect Mobius - but hides his depression with humor. In love with Sally.
Knuckles the Echidna
Sex: M
Age: 17
Profile: Joined the FF to deal with Angel Island's greatest threat, Robotnik. Feels quite guilty to have failed. Now truly is the last of his kind.
Miles "Tails" Prower
Sex: M
Age: 12
Profile: Born the day of the Coup, he has never known a normal life, or parental-figures other than Rosie, Julalya, and the Freedom Fighters. Is a mechanical prodigy, though not as skilled yet as Rotor or Sally.
Rotor Walrus
Sex: M
Age: 19
Profile: Mechanical genius. Usually doesn't go on missions, and is quite thankful to have gone on the BEFPG mission.
Antoine De'Coolette
Sex: M
Age: 20
Profile: Oldest of the FF, but always acted incompetent. Strangely, he seems a bit more competent now. Has a crush on Sally.
Sally Alicia Acorn
Sex: F
Age: 17
Profile: Second in command of the FF, leader of Knothole, former Princess and heir-to-the-throne of the Acorn Kingdom. Fell into a dark depression after the Pulse. In love with Sonic
Bunnie "Rabbot" Rabbit
Sex: F
Age: 16
Profile: Kind-hearted, soft-spoken southern belle... She was rescued from a roboticizer while it was running, leaving her with mechanical legs and a mechanical left arm. It is uncertain whether she can ever be deroboticized or how long her mechanical parts will remain functional.
Amy Rose
Sex: F
Age: 16 (biological) / 6-10 (chronological)
Profile: Thanks to her Tarot-based precognition, she knew she'd one day mate with Sonic since before she even met him (despite the fact that at the time, she was a pre-teen and he was 15). Thanks to time travel? she is now the same age as him. She regrets that she made Sonic and Sally uncomfortable by assuming there would be romance between Amy and Sonic, but she regrets far more that she didn't understand her premonitions of the Sterilization until it was too late (and that they could not put the time travel to use to save the world).
Rouge the Bat
Sex: F
Age: 22
Profile: Got her start as a jewel thief, but was recruited into GUN and served as a spy against Robotnik for several years. When Station Square fell, she joined the Freedom Fighters. Has a thing for Knucles, but hasn't fully gotten over the death of her old girlfriend, Topaz. (She's also attracted to Sally, and flirts with her, but doesn't expect Sally to ever go for it.)
Mina Mongoose
Sex: F
Age: 16
Profile: Lived in Moonbrook Village, a village destroyed not long before the Pulse. Was in a holding cell awaiting roboticization when the Pulse hit, and was rescued by the FF.
Cream the Rabbit
Sex: F
Age: 6
Profile: Despite sharing a family name with Bunnie, no familial relationship between them is known. Like Mina, lived in Moonbrook until it was destroyed.
