Sonic the Hedgehog, Vol. 21: Reprise

Sonic and the Chaotix continue their mission to shut down Clean Sweep Inc. for good. The defeated Clutch gives them hints about a former facility where only automated systems are supposed to be running. They get backup from Shadow and Rouge, who are also investigating Clean Sweep. But the downloaded data contradicts Clutch’s story – and Rouge warns Sonic that Tails’ isn’t the only Chaos Emerald that has recently gone missing.

While Sonic wonders who is behind the Emerald thefts, he has no idea that someone is watching him. Who is it – and why? Volume 21 collects issues #79–83 of the Sonic the Hedgehog comic series along with the one-shot Chasing Shadows.
