Actually 8 is her age in Sonic CD and 12 is her age in the games. In the Pre-SGW comics, Amy was 8 or 9 when she appeared for the first time (it was in 3235, the year when she turned 9). Then, sometime in 3236, she used the Ring of Acorns to make herself 16. The Super Genesis Wave happened in 3237 and at the time Amy was 11 (biologically around 17). In the Post-SGW comics, she is 12.
