13th Hunter Chairman Election arc
Abilities & Powers
As one of the Hunters hired by Battera and part of Tsezguerra's team, Barry is at least a decent Nen user, as confirmed later when Gon's team and Goreinu enlisted the help of other players to acquire "Patch of Shore". He is also a skilled boxer who managed to defeat the Pirate boxer without taking even one hit, which is a remarkable feat, considering the latter managed to knock out an adversary with only one uppercut to the chin. He might specialize in infighting, although it is certain he resorted to this strategy simply to gain the advantage against his opponent's Emission attacks. He is very fit, and capable of chaining a barrage of punches until the adversary in knocked out.
