File:Sonic X Episode 53 - A Cosmic Call

Description
Super Sonic is fighting against a mysterious robot. Super Sonic is unable to defeat him and he sends the Chaos Emeralds away to avoid his opponent to take them from him. Without the Emeralds, Sonic loses his energy and he falls to his planet. Another robot (known as a Metarex) follows him. Back on the planet, Tails, Amy, Cream and Cheese are watching a meteor shower, when a ship almost crashes into them. They follow the ship and find a strange girl lying unconscious by the ship. Meanwhile in Eggman's base, Sonic wakes up and Eggman tell Sonic how he found him on the beach, and that he has waited nearly a week to find out what happens. Rouge the Bat watches from above and Sonic leaves Eggman's base.

In Cream's house, after introducing themselves, everyone is surprised by the arriving Metarex who starts destroying the forest with laser beams. The last Metarex was able to finish his duty: which was to remove the "planet egg". A strange girl named Cosmo explains that the planet egg is the lifeforce of their world. Sonic, Tails, and Knuckles make a last effort to save the Planet Egg, but the Meterex escapes. Cosmo tells Sonic that he is the final hope to save the galaxy. At the same moment, Chris (who is now 18) completes his new machine that will transport him to Sonic's world. It works, but Chris arrives in his 12-year-old body. The reason this happens is because a year on Chris' world is only a month on Sonic's, meaning that it has only been 6 months since Sonic and Chris last saw each other.
