I have no idea either he doesn't exist or you just have to try to unlock him.

You have to beat all missions with rank S or A iI think for A But when you do for S you
unlock SOme kinda spirit thing and nights and Super Sonic!

just like what super sonic said beat all missons on extreame

beat all babylon races

you cant

i dont know

you can unlock super sonic but you have to get extreme on all the mission

He is NOT a chacter ita a gear that you get: a chaos emerald you have to do all missions
wth extreme to get the chaos emerald.

prrrrrressssss A

Unlocked How:Get Extreme Rank on all missions.
Unlockable from this:Chaos Emerald Gear
Upgrades:1=Ring Capacity Up
2=Ring Capacity Up
3=Magnetic Barrier
(He runs on rings)

i dont have this game but i want it

IDK if it actually possible,cause I have every character but the one on the top very
right,still don't know who that is,btw.But you can get a chaos emberald in Sonic Riders
for gamecube as an air ride,it can only be used by Sonic,and when you use that air
ride,Sonic becomes Super Sonic.

you must collect 100,000 rings and a new type of gear will appear at the shop for 100,000

you must get extreme on all the missions
