Gnarl is an aged brown Minion and the Minion Master. He also advises and guides the Overlord. By his recurring appearances in all the Overlord games, it can be assumed that he is over a hundred years old, and that other Minions could, if given the chance, live to be this old and older.
Overlord: Dark Legend
Gnarl first encounters Lord Gromgard as an infant, telling him that he has great things in store. For sixteen years Gnarl hides out in an Iron Maiden within the room of the previous Overlord, awaiting the day that Gromgard turns sixteen and his powers as an Overlord are unlocked.
Gnarl is an aged minion who leads the minions between Overlords and acts as the narrator and advisor throughout the conquest. Even though being the frailest minion of the tower, he is the most experienced and knowledgeable, conducting various tasks like restoration of the tower while the Overlord is away and introduces new options and powers to him as they become available. He reflects the multiple paths of corruption the Overlord can take with his tone of voice and speech varying between light and black humour and always reminds the Overlord that "There are evil deeds that need doing." Upon arrival of the previous Overlord he is quick to betray but also appears less enthusiastic and reassures that if the current Overlord succeeds that he will "happily take him back".
Overlord: Raising Hell
After the Third Overlord is trapped in the Abyss, he states that while many Overlords have come and gone he had a "soft-spot" for him, with the other minions mourning their loss. But Gnarl believes he can find a way to escape the Abyss.
Gnarl serves the same role as he always has. It is revealed in the end cutscene that he may be simply pretending to obey the Overlord, and may even be setting him up to fail by his hand as hinted at by his stereotypical evil laugh at the end.
