USA: 17 October 1999
well the freedom fighters are shown in Sonic the Hedgehog series and Sonic Underground series. both series are tv series.
Sonic from Sonic X would ask who Sonic the freedom fighter was and then the freedom fighter said he was Sonic the Hedgehog and they would start a huge fight and in the end Sonic from Sonic X would win because Sonic Underground is dumber than Sonic X. well, for one, that cant happen because both tv shows were based on the same character, but with different meanings. my point of view is sonic underground sucks, and sonic x rocks! :D but that's just me. from mf842
