Archie Sonic the Hedgehog Issue 91 was the ninety-first issue of the main Sonic the Hedgehog comic series.
The Comic starts out with Rotor in the Forbidden Zone climbing up a mountain attempting to find a way home. As he gets to the top he is startled as he sees two "meteorites" falling from the sky and ducks as they land ahead. He gets over the cliff to see that if it hadn't been for the Energy-dome they would have stuck Robotropolis. He tells himself that although the city isn't Mobian friendly he needs to check out the crash site, and at first eh has trouble seeing through the smoke, but then he starts he hear a voice calling for Sonic. Out of the smoke comes Mina Mongoose who is looking for Sonic and Rotor explains that he's a friend of his. Then after Mina explains she thinks Sonic might be there, he drills up from underground.
Sonic is thrilled to see that Rotor is back, but Mina is angered as she says two giant thingies feel from the sky, and she wonders how he even survived. Sonic explains that he saw them coming and simply burrowed underground to safety.
At Doctor Robotnik's base, Eggman is examining the Sword of Acorns talking to himself about how he thought the meteorites had killed Sonic, and so he will take down the energy-dome, and see if the Sword of Acorns can actually restore Mobian free will, as the Robotic Uncle Chuck and Muttski enter the room. He takes the Sword, about to strike Uncle Chuck down but then throws the Sword away saying it's unsatisfying if he isn't there to see him do it and leaves.
Back at Knothole Elias has been alerted to the Sword of Acorn missing, and says that he has difficulty believing that the Secret Service wouldn't have noticed someone come in and go, and wonders if this could be the handiwork of thieves, but Geoffrey shoots this down because the Sword is the only thing missing, and they the person had come for it specifically.
At the Knothole Medical center Sally is thinking to herself that her whole family had been reunited only to find out that her father is paralyzed from the waist down.
Nate Morgan comes in looking for Max saying he came as soon as he heard, and that he should never have gone into battle. Dr. Quack says that its a bit too late for that, and he says that maybe Nate should accompany the Queen and Sally outside and let the King rest.
Back with Rotor, Sonic, and Mina Rotor is saying it's just like old times: them verses Robotnik, but Sonic says that it isn't the same Robotnik; this one is from another zone and is ten times as evil. He grimaces as he tells Rotor and Mina to get back to Knothole, and when Mina asks him what he would do, he explains how he lost the Sword of Acorn to Eggman, and now he needs to get it back.
In Robotnik's base Arachnis had just stolen the Sword of Acorns when Uncle Chuck breaks the silence and revels that he and Muttski have actually gotten their free will back, but they couldn't have fought Arachnis or else it would bring too much attention, and it would be better if she had it or else Eggman might have found out it gives Robians free will. He looks on the screen where Sonic is fighting the SWATbots, just when Eggman is coming back. Eggman is ranting about Sonic not knowing when he's beat when he discovers the Sword is missing. He tells himself not to get upset because he thinks it didn't even work. He then turns to Uncle Chuck and Muttski and says to himself he'll let Sonic fight for a lost cause, but he won't compromise the Shadow-bots.
At Knothole Queen Alicia is talking to Nate and Sally, when Nate excuses himself saying that she and the princess have some catching up to do. The Queen asks Sally whats wrong, and she replies her father's situation, and she's worried about how Elias is doing with the missing sword business. Queen Alicia says she's certain he's doing fine and that he was Born to it, and this makes Sally think "Born to it yes, but definitely not bred."
Outside Knothole Rotor and Mina are just getting back, Rotor finding out that everyone relocated after Robotnik invaded, and asks if Mina is a new Freedom Fighter, to which a stunned Mina says she's just a babysitter. Rotor is then about to ask why she was with Sonic when Elias and Geoffrey see Rotor and greet him.
Beneath the streets of Robotropolis Arachnis knocks on a door, where a dark figure asks if she got it, and then says that was a stupid question: of course she did, before taking it from her and reveling himself to be Kodos.
Above the surface Sonic is wondering where laughter is coming from, when Eggman gets on loudspeakers sending the Robians after him. Sonic runs away then, while Uncles Chuck thinks to himself that he is sorry but someone has to keep an eye on Robotnik.
Sonic is racing past the meteorites when he realizes that they aren't meteorites at all; they're aircraft. The doors open up and Sonic says "Now THIS I don't believe."
