Was just talking about this on another site, and it's interesting to note the various currencies of Planet Zi.
Some of the cannon references are:
- "G" in Zoids Legacy
- "Gallos" in ep 28 of CC
- "BP" in Zoids Battle Legends (probably: battle points, not a real currency)
- Various currencies exist in Genesis (ep 28)
- Zi-dollars, ep 17 of Fuzors
Anyone else know of any to add to the list?
