A yellow-name Ganador, he can be challenged when the World Clock is set to the 15th Century's third through fifth periods, or if one equips Adept of Ages (15th Century-P.3) / Adept of Ages (15th Century-P.4) / Adept of Ages (15th Century-P.5) titles or Age effect (15th century) EX Effect equipment.

Can potentially drop the following when defeated:

Medium Storm Sail
Festival Wooden Paneling (note: presumed to be a JP-server drop only due to Maris Ganador nerfs)
Spanish Crest
Spanish Admiral Outfit
Blessing for the Victor
Flag of Spain (confirmed to be removed on Maris server)
