Huh. More generic animal-people around might've made a lot more sense during that whole arc where Sonic's world and Earth started merging. Or even during the last season where Sonic's planet seems strangely devoid of any intelligent life barring the core cast. The humans aren't a big deal for me. Though it might help the suspension of disbelief if there were other animal characters who stood around like helpless sheep with them, or just more humans like the GUN Commander who were obviously attempting to do something about the current crisis.
