Sonic Unleashed 2:Dark Gaia The Return is the next game in the Sonic Unleashed series. As in the title,Dark Gaia returns from defeat. Chip returns,but takes form of a brown hedgehog with white stripes on his head and a green ring on one of his left fingers.


After his last encounter with Dark Gaia,Sonic has been free of his Werehog problems (from Sonic Unleashed) for over 8 months,but that's all about to change. Nazo revives Dark Gaia and fuses with him to make Dark Nazo Gaia. Meanwhile,Sonic is taking a stroll through the city of Spagonia when the sky turns darker. This can't be! Sonic thought Dark Gaia was sealed away 3 years ago! Then,Sonic felt a rush of negative energy go through his body. He knew he was turning into Werehog Sonic. 'RAWR!' yelled Werehog Sonic,"Wait, where's Chip?" Then,Sonic saw a lime green light appear in front of him. A brown hedgehog was appearing. "Hello Sonic," said a familar voice,"It's me,Chip!" Sonic was shocked at seeing his once winged-dog friend now a hedgehog. "Nazo fused with Dark Gaia,"Chip said,"He's going to unleash Perfect Dark Nazo Gaia!" "Let's go!" said Sonic.
