A white-name Ganador, he can be challenged when the World Clock is set to the 15th Century's fourth through fifth periods, or if one equips Adept of Ages (15th Century-P.4) / Adept of Ages (15th Century-P.5) titles or Age effect (15th century) EX Effect equipment. Defeating him -- or another Ganador, Khalil Pasha -- once is required in order to unlock access to Kemal Reis as well.

Can potentially drop the following when defeated:

Small Storm Sail
Venice Military Paneling
Venetian Crest
Famous Admiral's Staff
