that would be a hard one sonic runs at full speed 749mph but
superman at full speed flys
100000000000000000000000000000000000000000000000000000000000000000000000000000000000000000mph
but in sonic and the rings sonic runs
10000000000000000000000000000000000000000000000000000000mph so
superman is faster but if sonic went sonic unleashd and did a sonic
bost he could run faster then the speed of light and he never ends
in speed sonic would just get as fast as he wanted to so all
together sonic the hedgehog is faster then superman and anything
else go!!!!!!!!!!!!!!!!!!!!!!!!!! sonic the hedgehog
i think sonic because sonic is even faster than cheetahs:D
