Marquis de Léon (Keeleon in the NES version) is a character in Dragon Quest IV. He controls the Palais de Léon, in the form of a lion monster.
The Marquis de Léon originally uses Balzack as a subordinate, but after gaining further power and no longer needs his help, sending him off to Zamoksva. According toThe Unknown Legend, he is the prince of the castle Palais de Léon, who used the Secret of Evolution to assume this form, and the remake depicts him accordingly: When the monster is defeated in the remake, he returns to human form, and forgets his memories as a monster.
He must be fought twice, once each in the fourth and fifth chapters. It is supposed to impossible to defeat him in the fourth chapter; if he is defeated, the PlayStation version will carry on as though the party lost, and the FC/NES version will repeat the battle. He moves twice per round, attacking, casting Sizzle and breathing frost.
