Ganzo

Ganzo was a character that appeared in the first One Piece movie. An oden chef and grandfather of Tobio whom the Straw Hat Pirates met. He was also the childhood friend of the legendary gold pirate, Woonan.

History
When they were young, Ganzo and Woonan had an argument about how important gold really is. Ganzo believed that gold could not bring happiness. During the fight, they fell over the cliff they were on, hanging onto Woonan's pirate flag. Knowing how important the flag is to Woonan and that Woonan could not hang on for much longer, Ganzo lets go so the flag would not be ruined and Woonan could climb up. Fortunately, Ganzo was rescued by a passing ship and woke up days after the accident to find that Woonan had already left to become a pirate. They never saw each other again.

When Ganzo, Tobio, and the Straw Hats finally find Woonan's crypt several years later, it was empty save for Woonan's skeleton, flag, and a dying message. Ganzo was surprised to find that Woonan had realized what Ganzo told him was true, and thought of their friendship as his most valuable treasure, rather than the actual gold itself.
