Sonic Universe was an American comic book series published by Archie Comics in association with Sega, based on the latter's Sonic the Hedgehog. It is a spin-off of the comic book series of the same name, and shared continuity with that title. Sonic Universe centers on several characters featured throughout the franchise and comics, including Shadow the Hedgehog, Blaze the Cat, and Silver the Hedgehog.
The series follows a unique format, in which its lead character and story arc change every four issues, and usually occur concurrently with those in the flagship Sonic title, though within different locations. Sonic himself usually does not appear in these stories, except for occasional supporting appearances.
Fleetway, the producers of the UK-based Sonic The Comic series, produced a similar series of stories called "Sonic's World" from issue 26 onwards; it, too, expanded the fictional universe, following various characters in the Sonic universe on their own adventures, which eventually crossed over into the core series on numerous occasions.
Sonic Universe was published monthly by Archie Comics alongside its parent title Sonic the Hedgehog. The first issue was released in February 2009, following the cancellation of Sonic X; issue #94 was the last, released in January 2017. An official Sonic Universe blog was run on Archie Comics' website that would occasionally go into further detail about the events in the stories, such as revealing what happened in the alternate timeline Silver the Hedgehog traveled to in The Silver Saga after he left, but it has since been discontinued.
The series subsequently surpassed Knuckles the Echidna as the longest running spinoff of the main series.
In July 2017, Sega announced the discontinuation of their business relationship with Archie Comics, and thus the latter will no longer release any further Sonic the Hedgehog comics, including Sonic Universe.
Synopsis
Issues #1–50
Issues #1–4, entitled "The Shadow Saga", follow Shadow the Hedgehog continuing the events from Sonic the Hedgehog #196 and Sonic X #40. Shadow and Metal Sonic end up on the alternate world that is home to Blaze the Cat, who teams up with Shadow to help him defeat the robot and return to his own reality. Following this, Shadow and Rouge the Bat team up with Sonic the Hedgehog to neutralize a weapon that Dr. Eggman intends to use against Sonic's team of Freedom Fighters and possibly other forces opposed to him. This was followed by Shadow's first encounter with future teammate E-123 Omega, and the pair teaming up with Rouge to become Team Dark and retrieve a Chaos Emerald.
Issues #5–8, covered "Mobius: 30 Years Later", featuring a return to a possible alternate reality visited in the main series. In this arc, time-traveler Silver the Hedgehog travels to this time period in an attempt to thwart events that will bring devastation to the future from which he hails. In the process, he ends up joining forces with a new team of Freedom Fighters, made up of children of the heroes from the present reality of the series, to thwart the evil King Shadow the Hedgehog, who unleashes a monstrous fusion of Tikal and Chaos from the video game Sonic Adventure.
Issues #9–12, known as "Knuckles: The Return", in which Knuckles and his teammates, the Chaotix, set out to capture the Echidna villain Dr. Finitevus and punish him for his recent involvement in Knuckles' brief possession by the evil entity Enerjak. As a result of the search, they end up fighting Dr. Finitevus and his temporary allies, a chapter of the Dark Egg Legion composed almost entirely of Platypus members, led by Grandmaster Bill, a former Freedom Fighter. They are joined in battle by the Downunda Freedom Fighters, the local chapter of heroes defending the region. This arc also introduced Thrash the Tasmanian Devil as a temporary Freedom Fighter member, but who acts recklessly and shows particular animosity towards echidnas.
