Barry has a youthful appearance and a sculpted physique. He has freckles on his cheeks and chest, a cleft chin, and fair hair that is short and spiky. He is most commonly seen wearing the same military-like attire as his teammates, with the addition of a cap worn sideways.
He follows Tsezguerra's orders, and is cautious and fairly observant, worrying that Genthru's team was close to clearing the game after they took at least five cards from them. He alerted the group to the fact that Genthru had reached 97 specified slot cards, and also took note of Gon's extraordinary ability, pointing out that he was the only one to stand his ground against one of Razor's throws.
At some point in his life, Barry took and passed a Hunter Exam and learned Nen. He, Kess, and Rodriot have been working with Tsezguerra for 20 years, and were hired by Battera to clear Greed Island.
Greed Island arc
While on Greed Island, the team collects as many as 95 different specified slot cards before contacting the Bomber to trade. During the trade, Genthru diverts the team's attention while Sub and Bara steal two cards from each of them, breaking their monopolies and acquiring rare cards, among which were Barry's duplicates of "Fledgling Novelist" and "King White Stag Beetle". The Bombers then escape to Masadora. Tsezguerra does not give chase, realizing that Genthru is in fact the Bomber. Barry worries that Genthru's team may have acquired all 99 specified slot cards, so Tsezguerra casts "List" on "Plot of Beach", learning that no player has acquired it yet. They resolve to find it before the Bombers and establish a monopoly. They thus head to Soufrabi. They are, however, unable to discover how to acquire the card. Not long after, Tsezguerra is contacted by Goreinu, who meets up with him and Rodriot to negotiate an alliance to get the card while Barry and Kess hide in the bushes. After listening to Goreinu's explanation of Razor's challenges, Barry volunteers for boxing, stating that he has a strategy. After one week, the alliance confronts Razor and his pirates. Barry is the first to compete, and his in-boxing style prevents his opponent from using his Emission abilities. Barry easily overpowers him and scores the first win.
Because of their victories, Barry, Kess, and Rodriot are unable to participate in the dodgeball match, so they watch from the sidelines, administering first aid to Tsezguerra and Gon. After their victory, Gon takes the original "Plot of Beach" while Tsezguerra's team settles for a copy. The Bombers immediately find out and threaten Tsezguerra, assuming that he has the original. He strikes a deal with Gon's group to hold off the Bomber for three weeks in return for "Wild Luck Alexandrite". They restock on transportation spells before meeting up with the Bombers.
When Tsezguerra's team meets with the Bombers, they refuse to hand over the card and take cards from them before escaping. Goreinu gives them the transportation spells he has collected. Over the next nine days, Barry assists in launching hit-and-run attacks against the Bombers. One week later, the Bombers fly to them, and Barry takes over as the "Accompany" caster when Tsezguerra runs out. When they exhaust their transportation spells, they leave the game, only to find Battera's mansion empty except for Sabazushi and the billionaire himself, who has canceled the reward and locked himself in his room without explanation. When the Bombers arrive, Tsezguerra's team escape with Battera, quitting the game for good. They learn that Battera offered a reward for clearing the game so he could save his comatose lover, but she died one month earlier.

Abilities & Powers
Barry is capable enough to have passed the notoriously difficult Hunter Exam. As one of the Hunters hired by Battera and a member of Tsezguerra's team, he is at least a decent Nen user, as confirmed later when Gon's team and Goreinu enlisted the help of other players to acquire "Plot of Beach". 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 had previously managed to knock out an adversary with a single uppercut. By boxing as an in-fighter, he was able to completely overwhelm his opponent, proving himself not only a skilled boxer, but also a good tactician. He is very fit and capable of chaining together a barrage of punches until his adversary is knocked out.
