Last time on The Return of an Enemy.
Sonic fought the new Metarex leader...
"You thought you could defeat us. But we grow stronger instead." said a strong, hateful voice that echoed in the distance.
"No, I am not. I am the new leader of the Metarex and you will hand over the Chaos Emeralds. We shall spare you and your friends if you do so." spoke the Metarex leader.
...while his friends fought a Metarex...
"It's a Metarex!" shouted Tails.
...and some plants...
Suddenly, something from the ground grabbed Cream's ship preventing it to move.
"It is a tree root!" shouted two-tailed fox.
Then more tree roots grabbed the X Tornado and Knuckles.
...Sonic had another fight with the Metareax leader...
"Then I guess you have to beat me first." spoke Sonic.
"I was hoping you would say that." replied the figure.
...but they managed to get away with the Master Emerald and planet egg...
"Oh. By the way Sonic, thanks for the Master Emerald and Planet Egg." spoke the leader.
They all quickly look at the other Metarex. It had the Planet Egg and the Master Emerald in each hand.
...and the race is on to stop the Metarex once more.
"Well, we should rest for the night and prepare our ship." said the two-tailed fox.
"Lets move it then." said the echidna.
They all shouted in unison and returned to their work.
