Walhart is an indomitable force, suited for a conqueror, destroying all who stand in his path to glory. He hates losing and turning his back to an enemy more than anything and believes that only through power and calculated ruthlessness can the world be united and usher an era of peace. While he holds down his opposition by force, he has the charisma needed to lead a country and sway others to join his cause. He is perceptive of others, knowing some of Excellus' schemes long before Chrom's army attacks Valm Castle, however he did not realize the full extent of Excellus's manipulation until his final defeat by Chrom. He is considered to be the second coming of the founder of the Valmese Empire, but he lacks compassion, or so it would seem, due in part to not having a compassionate queen like Celica by his side, as the first king once did. From his support with the female Avatar, it is revealed that he truly sought to destroy the Grimleal, but along the way he was manipulated from within. He is strict and can be hard to understand due to the way he talks, but becomes easier to understand after joining Chrom.
