Amy Rose is the first, the main female character and the only female character who is just a hedgehog as main character Sonic, when she was not supposed to be Sonic's girlfriend, who is a male hedgehog in the Sonic the Hedgehog series. Designed SEGA and Sonic Team Amy Rose just for fun?
Previously I thought that was Amy Rose Sonic's girlfriend and that he ran from her Sonic Adventure for he was shy, and it is not usually that someone is shy for someone they are in love?
The most important female characters usually being or becoming romantically to the male protagonists and be in the same species if they were animals for example in movies, games and TV shows.
For example this couples:
Mario x Peach
Mickey Mouse x Minnie Mouse
Donald Duck x Daisy Duck
Stitch x Angel
Bunny Bugs x Lola Bunny
Chipmunks x Chipettes
If Sonic said that he loves Amy Rose and meant it in Sonic X episode 52 in both Japanese and French version, why not Sonic returns his feelings again to Amy and continue to be annoyed by Amy's devotion like before in the rest of Sonic X?
