No only Super Sonic is an available alternate form for Sonic.
Hyper Sonic is a more advanced version of Super Sonic, that was only ever in one Sonic game: Sonic 3 & Knuckles for the Genesis, he is not in Sonic Riders or any other Sonic game. As for Super Sonic, you can only get him in Sonic Riders by completing all missions with a gold rank. *trust me it's not worth it, way too much work for the reward*
Sonic riders, Sonic Riders: Zero Gravity and Sonic Free Riders already exist.
Sonic Free Riders is the third instalment in the Sonic Riders series.
No, you can not by Hyper Sonic in Sonic Rush. For Sonic to go Hyper, he needs the 7 Super Emeralds, which Sonic Rush does not have. The Super Emeralds were only in Sonic 3 & Knuckles, so Sonic can only go hyper in Sonic 3 & Knuckles.
