Frey is a tall man with shoulder-length fair-colored hair. He wears an overcoat with short sleeves over a black top. He wears gloves and wields a whip. Like the members of his gang, he wears a blue bandana around his forehead to show his affiliation.

Plot
Bruno recruits Husky and Senri into his gang to strengthen his numbers before searching for the treasure that will make him head boss. After hearing that Frey has also recruited two children, Bruno takes his gang up to the Purple Rocks to search for the treasure. There he ambushes Frey's Gang, and taunts Frey. During a fight with a Red Rock-Dragon they locate the treasure but it falls into a lake. Bruno takes his gang back to town to prepare to retrieve it.
