Not the best Sonic animation series since it looked more like a darker version of sonic satam, but at least the underground Sonic can run up walls and cliffs and form his won tonarto ( not the bi-plane, the assault) and the underground isn't an absolute numbskull has the boom ones are.

I wonder, how is this thing getting good Reviews. This series has nothing to do with Sonic, and Manic and Sonia are some of the worst characters I've ever seen. Can not also bypass these embarrassing, childish songs, thanks to which all three of them, telepathically communicate? seriously Sega ?? This is probably the most embarrassing thing that I heard this month. Omin Sonic Underground, do not watch it.

OMFG this cartoon got 5 good reviews? The acting is more cheesy than adventures of sonic the hedgehog, the characters are annoying too! Before I go on we have the same voice actor of sonic from the 2 past cartoons. Why am I ranting about that? I think Sonic Adventure was released and that had voice acting. OH would you like to hear double d I mean SONIC sing well I hope you don't!

Really? I can see why people like sonic x but people like this cringy mess? It tried so hard but failed. The songs are the most cringy thing I've ever seen. The episodes them self are boring and again full of cringe.
