Shattered World Crisis

The Shattered World Crisis is an event that occurred in the Sonic the Hedgehog comics and its spin-offs published by Archie Comics. Taking place in the Post-Super Genesis Wave timeline, the Shattered World Crisis was a major global catastrophe occurring on Sonic's World, where the planet was torn into multiple pieces by the excess energy from Super Sonic's interrupted attempt to undo the Super Genesis Wave. During this crisis, the Knothole Freedom Fighters and their allies went on a world-wide quest to restore the planet back to normal with the Gaia Temples.

Prelude
The start to the Shattered World Crisis was sown when Dr. Eggman and Dr. Wily began reshaping their own worlds to their liking with the Super Genesis Wave. Super Sonic and Super Armor Mega Man, however, were able to defeat their nemeses and they each prepared a Chaos Control that could return their worlds back to normal. However, unlike Mega Man, Super Sonic did not quite succeed in his task as Eggman attacked him, causing his Chaos Control to be distorted when it restored the Prime Zone. As such, not only was the entire multiverse recreated and the timeline of the Prime Zone irreversibly altered, but all the excess energy from the Super Genesis Wave was applied to Sonic's World, energies that was too much for the fragile planet to bear.

Countdown to Chaos
Because of the excess energies trapped within Sonic's World in the new timeline, the planet began to experience global seismic activity manifested as earthquakes, and made as well a form of dark mutagenic energy leak out of the ground. During this period, Sonic and Tails sought and gathered the Knothole Freedom Fighters while Eggman and his lackeys made to the Death Egg Mark 2, with both parties seeking to survey the state of the planet. On their trip, Sonic was inhaled some of the dark energy, giving him occasionally crazy episodes. Eventually, however, the planet could no longer take the pressure and as such shattered into multiple continents hanging over the planet's core, marking the start of the shattered world crisis.

Early Hours
On hour zero of the Shattered World Crisis, when Angel Island was affected by the planet's break-up, Knuckles the Echidna left to find a weakened spirit meant to help with the Shattered World Crisis upon instructions from Tikal.

At this point, the Knothole Freedom Fighters and G.U.N. began their rescue attempts to save as many people as possible caught in the chaos, with G.U.N. launching Operation: Triage. The Knothole Freedom Fighters soon arrived at Station Square, which was next to a fault line, and tried to save the citizens until Amanda Tower and the UFAF Letter of Gabriel arrived to take over. Meanwhile, Team Dark and the Spider Troupe were send by G.U.N. to defend the battered planet from the return of the Black Arms.

After tending to Station Square, the Knothole Freedom Fighters figured out that Pickle and Charles' research could help them shred light on the Shattered World Crisis, but learned the professors had been kidnapped by Dr. Eggman, who hope to use their research to help him control the resolution of this crisis. Fortunately, the Knothole Freedom Fighters freed the professors from the Egg Train, though their research still ended up in the hands of Eggman. Pickle, then told the group that they could restore the planet with the Gaia Temples and the Chaos Emeralds. The Knothole Freedom Fighters thus began a search for both the Gaia Temples and the Chaos Emeralds. The Chaotix were later assigned by Sally to find the Chaos Emeralds. Soon after, the Chaotix joined up with Knuckles in their search which was made complicated by the Hooligans.
