When Worlds Collide Part Two: Mistaken Identities
The story begins with Mega Man (in his normal form, Rock), bringing Dr. Light a box of spare parts. Then Roll comes in and tells Dr. Light and Mega Man that Proto Man is trying to stop a bank robbery, but he's out-numbered.
Mega Man goes to help Proto Man, and tells Proto Man that he'll take care of this. Mega Man drops down right in front of the Roboticized Masters, and does the whole "Surrender now, and no harm will come to you" quote. Then it flashes back to Sonic's world, where he's running on a loop-de-loop in the Green Hill Zone (like in STH #226). He then begins to think about what might have happened to his friends. He went to Tails's house, but it was empty. He flew to Angel Island, but Knuckles was nowhere. He even went in Amy's room, figuring she'd be there.
Then it changes to show the Chaotix, looking for the same people. Charmy wants ice cream, but Vector and Espio say no, so Charmy goes off anyways. Charmy disappears, and then Espio notices someone in a nearby alley. Then Espio disappears, and Vector porrly armed goes into the alley, and asks if anyone's there, when Copy Robot jumps down and stuns Vector. It goes back to Mega Man's world, and him fighting the Roboticized Masters. Mega Man shoots off a charged shot from his arm cannon, and to his surprise it stuns the Roboticized Masters. The Roboticized Masters open a warp ring, and Mega Man is forced to go through it. Then it goes to Sonic who is greeted by Silver. Soon after that, Silver is stunned by Copybot, who runs off, mentioning the doctor "has other plans" for Sonic. Metal Sonic attacks Mega Man, who has only seen him as a "blue blur". Then Sonic, thinking Mega Man is the Copybot, spin dashes him into the ground. The two begin to fight, and Tails Man is watching and broadcasting live feed to Drs. Eggman and Wily.
Introducing "Eggman and Wily Failed Concepts." A glimpse is taken into Dr. Wily's master plan to combine the biomechanics of Sonic with his latest robot creation. The end result is a super-speedy Bass with blue quills and red shoes. Eggman says that he does not look any faster, measuring him with a measuring tape. Annoyed and humiliated, Bass then threatens that he will put an end to everybody.
- Every Sonic Universe issue from here on out would be released with a variant cover, a practice that had been confirmed by Paul Kaminski.
- The cover is an homage to the character select screen from the video game Marvel vs. Capcom: Clash of Super Heroes, where Mega Man appeared as a playable character. His appearance on the cover mimics his appearance on the character select screen of the game. Even his thumbnail artwork is identical to that of the game.
- The background on the variant cover is taken directly from the Sky Sanctuary Zone from the video game Sonic & Knuckles.
- This is the first Sonic Universe issue that is not a landmark issue (excluding Sonic Universe #1) to have a cover drawn by Patrick Spaziante.
- The first page in which Sonic appears, where he's running through a loop in the Green Hill Zone as the Genesis Wave fades out, is a direct throwback to the opening of the Genesis saga in Sonic the Hedgehog #226.
- Even though the reset "Worlds Collide" universe is based on that of the video games, the Master Emerald shrine, which appears briefly when Sonic is looking for Knuckles, still has its design from the comics' pre-Super Genesis Wave timeline as opposed to the one from the video games.
- The opening scene with Mega Man and Dr. Light includes a reference to Bond Man, an abandoned Robot Master concept from the original Mega Man game.
- On the main cover, Tails can be seen waving: the pose of his hand makes it look as if his middle finger and ring finger are practically fused together. This is a nod to an artistic quirk in artwork for earlier Mega Man games (dubbed the "Finger Phenomenon" by fans), in which characters would often be drawn with the same finger formation
