if I was to say who my favourite incarnation of Sonic was, it'd have to be the AOSTH one. I mean, this was the very first version that really gave Sonic a proper personality and voice, and it was really interesting to see him as a quick-witted character. The design is also a success in my eyes, as it retains the classic Sonic look, whilst updating it for the cartoon environment it is shown in. The design of his spikes give off a mohawken look, which really fit with his cool personality.I also love the idea of the version of Tails from AOSTH being not only his best friend, but also his younger adopted brother, emphasising how close they are.
