King Wo

King Wo is the military-minded king of Kaocho. He appears as an NPC in Golden Sun: Dark Dawn.

King Wo adheres to the example set by his predecessor from his city's homeland of Sana, Emperor Ko, who was aggressively expansionist and sought the secrets to eternal life. Before the start of Dark Dawn, the Tuaparang commander Chalis found her way into his court, which was previously comprised of just his two most trusted advisors Kan-Shuku and Meisa. From there, Chalis advised him to attack both Passaj and Ayuthay, kingdoms that contained the Alchemy Machines, potential power sources to Wo's conquest. Chalis knows in advance that her comrade Blados trapped the group of Adepts led by Matthew into the continent's southern Ei-Jei region, and that they will be coming to Kaocho in their attempts to turn on the Alchemy Machines so that they can cross over into the north region of the continent. Wo therefore anticipates Matthew's group and lets them come into his palace, where he tasks them to go into the Ouroboros dungeon below and retrieve the Sol Mask so that he may have Passaj's Alchemy Forge assisting his campaign to take over southern Angara. He also gives them a letter to prove to the Kaochan soldiers stationed at Ayuthay that the Adepts will be assisting in their attack on that kingdom.

The Adepts' discontent with helping an obviously evil man angers Wo, who has them dropped through a trap door into the Ouroboros dungeon below. However, Chalis assures him they will prove their use to him regardless; she predicts that Matthew will find the Ouroboros impossible to truly explore until he has gone to Ayuthay to hone his Psynergy and returns, where he will get the Sol Mask.

What eventually happens is that Matthew gets the Sol Mask, returns to Passaj, and uses it on Passaj's Alchemy Forge to activate it and turn Passaj into a well-defended fort city that will not fear Kaochan attacks any longer. King Wo realizes too late, if at all, that Chalis and the Tuaparang used him to get the Alchemy Forge started for their own sinister intents that become realized later in Dark Dawn. Later, when the Grave Eclipse occurs and shadow monsters start attacking much of Angara, many Kaochan citizens are killed, and the rest take refuge in Wo's palace.
