Sonic The Hedgehog

Dr. Eggman hands Sonic and Belle an unusual job: track down Metal Sonic, who has vanished without a trace. Their unlikely helper is Sage, the doctor's newest creation, and the two artificial siblings get along about as well as you would expect.

After tumbling into a lair built on illusions, Sonic realizes the missing robot is only one piece of a bigger scheme. Valuable technology is disappearing all over the world, and an unknown enemy is closing in on the Master Emerald. Sonic and his friends race to stop the theft before it is too late.

This volume gathers issues #84–88 of the ongoing Sonic the Hedgehog series plus the Sonic Racing: CrossWorlds one-shot, working as a satisfying story on its own and as part of the larger saga.
