Though the Hero is a silent protagonist (as is tradition in Dragon Quest games), he appears to have some semblance of a personality as illustrated through in-game dialogue with party members and his own family. The Hero is stoic and displays a strong, silent sense of dignity in his endeavors. He is fully devoted to his relationships, be it his family or his friends, staying with Prince Harry for the 10 long years they were forced into slavery while not once resenting the young Prince for what happened to his father. As a husband he is extremely devoted to his wife, often going out of his way to keep her safe during his quest (even when, in Debora's case, she treats him more like a slave then a husband) going as far as dropping all his responsibilities to his kingdom to go rescue his wife after she was kidnapped by Kon the Knight despite being advised not to do so alone. As a father, the Hero is protective of his children and has a deep bond with them; interestingly enough, their journey mirrors the one the Hero himself took with his own father years before. He is said to be a righteous king, governing fairly and well loved by his people.

There is something to be said about his courage. Since the age of 6, the Hero was already undertaking monumental quests without wavering; he is unshakable in the face of adversity, which is often commented by NPC's. He is also a fairly intelligent individual, managing to pass the Gothan rite of passage despite it's maze like appearance. He has an uncompromising sense of justice, helping everyone he comes across during his journey and doing right by them. He often goes through extreme trials and comes out on top, never faltering or wavering in his dedication to find his mother and restore balance to the world. Even when it seems things are at their darkest, the Hero will always persevere through sheer strength of character.
