Here's some FTL feats Sonic Colors: -Omega made calculations from Sonic and remarked that light speed would be exceeded by him, and Sonic replied that light speed is too slow for him (I think you know how Sonic feels about things about slower things).

-When Sonic did a mission for Espio by running around Planet Wisp, Espio remarked that he didn't even see Sonic when he came back (and with Espio running at hypersonic speeds and still being able to see clearly, his ninjutsu, and him being a chameleon in general, Sonic must have gone pretty fast...)

-Sonic remarked that he's faster than the Cyan Laser (Lasers go at the speed of light) -Outran a void for 30 seconds at less than half of his power/stamina.

Sonic Generations:

-Tails said that Sonic's speed alone can save time and space. -Sonic mentioned/asked that he can jog around the planet before they all yelled "SURPRISE!" for his birthday. -Outran Teleportation

Sonic Adventure:

-Sonic could perform the LIGHT SPEED dash and LIGHT SPEED attack. Tikal even stated that it was light speed in the cutscenes. In other games like Sonic Heroes, Sonic didn't rely on rings for it anymore, implying that he could now reach at least light speed movement with his own speed and not with a powerup or mechanic.

Sonic Cd:

-In Palmtree Panic, Sonic didn't have the Time Stones with him at first, so he needed to rely on his own speed to time travel. Sonic Rush:

-　Sonic traveled to another dimension (The Special Stages were deemed as other dimensions by SEGA) with just his speed.

Sonic Adventure 2:

-　Out-spinned teleportation (i.e. Shadow's Chaos Control)

Sonic Lost World:

-　Outran lasers

Sonic Unleashed:

-　Faster than the LSD by 7 times. On the speedometer, it only clocked at 328 spd, while Sonic boosting himself can go over 2100spd
