Gashta is a tall man with an afro hairstyle. He wears tribal-like clothes and carries a messenger bag with him.
Greed Island arc
Alongside his brother Zetsk, Gashta takes Tsezguerra's Ren test in order to play Greed Island, and they both pass. Right after entering the game from the Shiso Tree, he regroups with his brother and thanks him for waiting. After Gashta perceives that they are being watched, Zetsk confirms it and claims that there there are several. Gashta deduces that they are no threat and should be ignored. The brothers then head off together into the game.
The Bombers mention the Bellam brothers as players that they should keep an eye on. Gashta's name is mentioned in Gon's binder, and Goreinu also mentions the brothers as a strong and famous duo who never work with others. During Eta's announcement about the trivia game to win the "Ruler's Blessing" card, the brothers attentively listen. After Gon wins the trivia game, the brothers confront Gon and his team. Gashta comments on how they actually managed to get all of the cards in the game, while his brother Zetsk snickers. Zetsk then tells a man who was working for the brothers that his job is done, ordering him to leave and then challenging the group to a winner-take-all match. Gashta then tells the group that it's a match they can't refuse, but the brothers are handily defeated by Gon and Killua.

Abilities & Powers
Gashta is capable enough to have passed the notoriously difficult Hunter Exam. He is an above-average Greed Island player, praised as a capable individual by Goreinu and considered a troublesome opponent by Genthru despite only recently starting the game. He and his brother were feared by multiple players, although not as much as the Bomber. Gashta seems to be the leader of the two-man team. He is highly perceptive, having succeeded in sensing the presence of onlookers as soon as he joined the game, and making inferences about their species and skill level based on it. Nonetheless, the two were easily defeated by Gon and Killua.
