I believe Butz was used in the original Japanese version of FFV. They may have changed it to Bartz in the North American PSone version because we would think his name would be rather silly. Then again, we may start opening up a topic of how to pronounce his name...either "Butts" or "Buttzy"....:laughing:

It could be a translation thing also as to why in the PSone version they changed it to Bartz. The translated Emulator/ROM has it as Butz. I think I saw or read somewhere for the Japanese version that its Butz.

Try to think of it this way: In FFVI, Tina's name in the NA version is Terra by either a translation error or they edited it because in their opinion, Terra sounds better.
