|Sonic X #40|
- "The End": A peaceful gathering of Sonic and his friends remains anything but when Shadow the Hedgehog and Metal Sonic crash the party - literally! Even Dr. Eggman is reeling in horror over the souped-up Metal Sonic, but that doesn't stop him from forming an alliance to attack the blue blur. Meanwhile, Shadow remains inextricably linked to Metal, the only one who can help him find his correct place in the universe. It's a mélange of friends, foes and overlapping alliances... and Sonic and his friends are caught in the middle! This issue's title is only the beginning, as it leads into a brand-new series called SONIC UNIVERSE that promises to chronicle the outcome of the Shadow and Metal Sonic conflict, as well as the further adventures of the entire Sonic-verse!
Sonic is having a tea party with Cream which he promised her on what seems like a slow day. However Shadow shows up out of nowhere battling Metal Sonic. Sonic is then talking to Shadow about multiple universes while showing Shadow the town. While they meet up with Chris, Metal Sonic meets this universe's Eggman. Eggman later attacks Shadow again and Shadow warps Metal Sonic and himself to another dimension.
- This is the last issue of the Sonic X comic series.
- However, Sonic Universe would later replace this series.
- Shadow and Metal Sonic appeared in this world via Chaos Control from Moebius in Sonic the Hedgehog #196. At the end, Shadow would use Chaos Control again, this time ending up in the Sol Zone, as seen in Sonic Universe #1,
