French Title: L' arrivée de Sonic (Sonic's arrival)

They all try to catch him but Sonic's too stubborn and quick for them. So anyway, Sonic goes off and runs from the police. He then encounters Sam Speed and the S-Team!

But even at 500mph, Sonic is able to leave the S-Team in his dust.

However, Sonic is unable to stop himself before he goes off the end of an unfinished overpass. His speed is so great that he actually soars for awhile, looking down at all the beautiful sights. Eventually, he starts to fall, but ffortunately something is below him...a pool! He falls in and starts drowning, not able to get up!

Sonic then hears on the TV that Cream and Cheese were found. Chuck sees this and agrees to help Sonic find his friends. Cream and Cheese have been taken to Area 99; a top-secret military base. It is very high security, so Chuck gives Sonic an infrared scope to find his way around. Sonic finds Cream and Cheese in a lab being tested. He breaks them out, but then the security cameras catch him and start firing their lasers at them. After the cameras' lasers destroy about half of the base, Sonic hears a noise outside.

Knuckles declines and heads off for the forest. This episode perhaps is the most violent one to date due to numerous presumable deaths examples are: a beach full of people being completely destroyed, a massive force of police officers being burned by a heat ray (although, there was at least one survivor, yet a burned body could be seen in the distance), and a building being abruptly destroyed with many people inside.

Tails defeats the robot and Sonic and Knuckles continue to battle. Knuckles finally figured out that Eggman tricked him and he takes care of Eggman.

This is the first in-series exhibition of animals from Sonic's world other than the main characters. It also implies that the games' Tornados 1 &amp; 2 are the same plane "exactly".

Luckily for them, Tails has just finished to build his new invention: a big flying fortress called the Blue Typhoon. Unfortunately, his new ship used to be powered by the Chaos Emeralds.

They also discover that Cosmo's people were able to transform into huge dinosaur-like beings to protect their planet from an alien invasion. However, a few of them wanted to be able to completely destroy the alien hoarde, and so crystallized the Planet Egg in order to keep the transformation from sapping their energy. They eventually led to the abandonment of the planet and transformed into the Metarex.

Cosmo, horrified by the fact that the Metarex are using her to spy on them, intends to leave, but Tails reassures her that they all will help her defeat the Metarex. Sonic and the rest of the gang also support the new resolution, and they all are ready for an attack on the Metarex, maybe the last attack.

At the end of the episode, Bokkun arrives, telling Shadow and Chris that Eggman has been captured by the Metarex.

Episode 75: Agent of Mischief
French Title: Le jour des plantations (Plantation's day)

When Bokkun shows everyone Eggman's message (telling that the Metarex are starting to gather at galactic coordinates (0-0-0) because of a thousand-year prophecy), the gang starts lifting off to go beat the Metarex once and for all. Unfortunately, they leave Shadow behind! However, the Chaotix find Shadow and offer him a ride (for free, which is the surprising part) to galactic coordinates (0-0-0).

Once Sonic and the gang reach (0-0-0), they find the Metarex fleet there, ready while a Planet Egg warps in from another universe. The Egg is in the center of a planet of water, which, combined with the light of the Chaos Emeralds, help Dark Oak and two other Metarex to mutate into a giant plant-dragon mix! Sonic's fleet starts attacking the planet, but then Sonic is catapulted into the air by a pillar of water! Dark Oak then swallows Sonic, who plunges face-first into the planet.

"Ha! Now Sonic the Hedgehog, how can you hope to defeat us? Water is your weakness, and our strength! Now Forestation will be unstoppable!"

Meanwhile, Chris infiltrates Dark Oak's ship to blow Eggman, Bocoe, and Decoe out. At the same time, Shadow and the Chaotix fight more Metarex, Shadow asking every Metarex he comes across where Dark Oak is. Eventually, the ship comes apart to reveal a giant tree, which attaches to the aquatic planet and starts growing to an unimaginable size!

Episode 76: The Light in the Darkness
French Title: Inquiétudes pour Sonic (Anxieties for Sonic)

Amy tries to rescue Sonic from the watery planet, but everyone else keeps her back, trying to come up with another plan. Then, Rouge comes up with a brilliant idea: use the Master Emerald to cut off the energy supply to Dark Oak! The team charges up the Sonic Driver with the Master Emerald and fires it at Black Narcissus and Pale Bayleaf, destroying them. Unfortunately, after this is done, the Master Emerald shatters, and it is revealed that the Metarex have sucked up all the Chaos Emerald's energy!

Dark Oak's beast head becomes extremely weak because of a hit from the Sonic Driver, and finally ceases movement. The planet expands, taking Dark Oak along with it. Inside the planet, Sonic sees what happens after the Forestation process is complete. He manages to fight a bunch of sand monsters and plant-like tentacles, only to find out he's fighting in a dream. Suddenly, Amy spots Sonic inside the planet is able to get Sonic out of there, crashing through the roots into the water to rescue him.

Suddenly, the planet condenses into a giant seed-like object! Sonic stares at it, probably in despair.

Episode 77: A Fearless Friend
French Title: Cosmo à l' oeuvre (Cosmo in the work)

When the giant seed finally reaches the final stage of its metamorphosis and starts sucking the life out of everyone except for Cosmo, she takes the Chaos Emeralds to Eggman, thinking that he'll know what to do. Unfortunately, Dark Oak attacks Cosmo, who drops the Chaos Emeralds into space. Thankfully, they close in on Sonic and Shadow, who use them to transform into Super Sonic and Super Shadow and attack the Metarex seed. But, once they destroy it, they reveal an even smaller planet with a gravitational force that could potentially destroy the whole galaxy!

Cosmo feels helpless but her mother, in her mind, assures her that she is the one who will save the galaxy. She then transforms into a new form and becomes determined to stop this once and for all. She flies over to the planet, passes through the gravitational force that neither Super Sonic nor Super Shadow could pass through, and plants herself atop it. She then becomes a tree, saying that she has now immobilized Dark Oak. She tells Tails to load and fire the Sonic Driver and shoot it at the planet. Everyone is shocked and does not know whether or not to risk saving the galaxy if they're going to kill Cosmo in the process. Tails, however, is very hesitant, but Cosmo re-assures him that her seeds will be spread throughout the galaxy. He then thinks back to all of the good times they've had and their love and, tearfully, fires Super Sonic and Super Shadow at the planet, completely destroying it. Cosmo then greets Tails a final "farewell" vision saying she'll never forget Tails.

Episode 78: So Long Sonic
French Title: La renaissance des planètes (Planet's rebirth)

The episode starts off with Vanilla stopping by the Chaotix Detective Office to thank the Chaotix for all that they did for her and Cream. Amy and Cream then bring a whole bunch of snacks to Tails to try and cheer him up. (Note: This entire first part, almost four minutes long, was not shown in the English dub of the episode.)

Chris then flashes back to the point just when the planet with Cosmo on it was being destroyed. Lucas is seen following Hertia to peace. Suddenly, the planet begins to expend all of its energy. Punching Sonic out of the way (which looked very painful for Sonic), Shadow uses the last of his energy to perform Chaos Control to stop time, giving everyone else a chance to escape. Eggman then worries that Shadow may not have survived the Chaos Control he did to save everyone, and he begins to feel some remorse for Shadow. Meanwhile, Sonic approaches Tails with only a seed from Cosmo. Tails, already upset about losing her, finally falls into Sonic's arms, crying as they fly away.

Back on their homeworld, Chris and Knuckles have a little discussion about what's next for Chris, and they fall along the lines of where Chris's home would be now that he can't go back. Rouge is seen in Eggman's ship staring at Shadow's pod. After a run-in with Eggman, Rouge suspects that he knows something about Shadow's whereabouts. Near the end of the episode, Eggman shows Chris an egg-shaped pod that will take him home, but there's a catch: Chris only has three minutes to return home, or else he could be stuck in Sonic's world! Chris has no time to say goodbye to his friends, just as Eggman planned. Chris then leaves Sonic's universe via Eggman's pod. Once Chris is gone from sight, Eggman says that with Chris out of the way, he can continue in his creation of the Eggman Empire.

Sonic's last words were "I won't forgive you, Eggman!" ("Life never stays slow around here for long, thank goodness! Watch out Eggman, I'm coming at'cha full speed!" in the English dub). We then see a pot with a seed (apparently the one Sonic found) in it. The episode ends as the Egg pod with Chris in it flies out into space and then twinkles out. Chris was supposedly sent home.
