Which main theme did they go with for the US dub? When I saw it on Cartoon Network, I missed the opening. The one they used for the last part of the Japanese version is really undoubtedly the best of them (besides, what's not to love about an emo-punk band called Asian Kung-Fu Generation)

The dubs are really off. I think they probably just grabbed whoever was in the recording studio that day and had them read. I don't agree with the CN translation, and the voices just make me violent.
