Plot
Chris arrives in Sonic's world as his 12-year-old self. He makes contact with everyone and is introduced to Cosmo, but Sonic faints shortly after. Apparently, the recent battle had tired him enough to faint.

Meanwhile at Cream's house, Cosmo explains the Metarex goals and the consequences of the planet egg's removal. Cosmo also admits that she's the only survivor from her planet, which was eliminated by the Metarex.

Later on, Tails tells Chris that he created the teleport gate over six months. Chris finally realizes on Sonic's world it has been only six months since he said goodbye with Sonic. Chris explains in his world are six years and he's currently 18 years old. As Tails, Amy and Chris enter to Cream's bedroom to tell that to Sonic, they realize he had woken up and left by the window. Vanilla gives Chris the clothes which she made from her memories.

Everybody (except for Knuckles, who's suspicious of Cosmo) agrees that the Metarex must be stopped and they decide to go into space to destroy the Metarex and to find the lost Chaos Emeralds. Luckily for them, Tails has just finished to build his new invention: a flying fortress called the Blue Typhoon. Unfortunately, his new ship used to be powered by the Chaos Emeralds. Chris thinks that they could use the Master Emerald. Knuckles was growling wondering where Rogue went and notices the Master emerald's altar and The Master Emerald is gone. Knuckles disagrees, but with some female "persuasion" (aka: They beat him up), he finally agrees.

At the same time, another Metarex is sent to the planet in order to destroy Sonic and the Blue Typhoon. A fight engages between the Metarex and Sonic and Knuckles. With the help of the Typhoon's primary weapon, the "Sonic Power Cannon" ("Sonic Driver" in the original Japanese version), the Metarex is destroyed. Sonic falls to the sea, but Chris takes off in the Hyper Tornado and comes to the rescue.

While all this happens, Cream comes back to her house and asks her mother to depart too. Vanilla agrees and Cream hugs her to say goodbye. The Blue Typhoon takes off, but it is followed by Dr. Eggman and Rouge.

Trivia

 * Knuckles is partially right about Cosmo being on the Metarex's side, they're the same kind of species and Cosmo is an unwilling spy for the Metarex, as seen in episode 73.
