Night of a Thousand Sonics": A dimensional doorway has been opened in The Great Forest and out pops the Sonic Cyborg. After landing from the Cosmic Interstate, it seems that in his dimension Dr. Robotnik turned the Freedom Fighters into cyborgs. But this was a mistake as the FF's became so powerful that they invaded Robotropolis. In an attempt to stop them Robotnik roboticised himself and became the Robo-Robotnik! If he was evil before now he's worse, and he's set his sights on conquering all dimensions that exist! Thus a mass recruitment of Sonics and bots begin, as Sonic and the real Dr. Robotnik join forces all in hopes of stopping him! But Robo-Robotnik's not through as he recruits Evil Sonic to steal the Giant's Hand in the Neutral Zone, the key to opening Giant Borg and taking over! As Robo-Robotnik wreaks havoc on Mobius can the Sonics stop them?
