Hanse was a man of average height and build. He had dark skin, thick eyebrows, and a big Rumpole nose. He wore a plain tank top, pants, and boots.
Not much is known about Hanse's personality, but he becomes anxious when he realizes that he has a bomb attached to him after learning about the bomb placement conditions and becomes upset when weapons are allowed in the boxing match.
Greed Island arc
After receiving an invitation from Kazsule, Hanse's team comprised of Wong Li and Zeho attend a meeting with five other teams. Kazsule, who leads the meeting, proposes to the attendees an alliance between them all in order to figure out a way to stop the Bombers from completing the game. The alliance is agreed upon and, to prove their worth to the alliance, Gon's team divulges Genthru's abilities. Hearing the explanation of how Genthru's abilities work, Wong Li and Hanse are perturbed since both were touched by him. An alliance is then formed between the groups, and it's decided that the goal of the alliance is to monopolize a card that the Bombers haven't acquired yet. Killua claims that his team has the "Wild Luck Alexandrite" card, but it is deemed impractical to monopolize a card with a transformation limit of 20 and Hanse claims it'd be an arduous task to procure nineteen "Clone" cards. So Hanse then uses a "List" card to figure out if anyone owns the "Tree of Plenty" card, but discovers that it's impossible to hold its monopoly, as three people already own it. However, Montreux discovers that the "Plot of Beach" can be monopolized as no other player owns it. After discovering the card's location, the alliance travels to Soufrabi with an "Accompany" card.
Upon arriving in Soufrabi, Kazsule explains how to retrieve an SS-rank card, and the group splits up to find information on the card, until Kazsule finds a female NPC who has information on the "Plot of Beach" card and directs the alliance to the base of the pirates in town. After the group makes their way to a local bar, they are challenged by Bopobo to a sumo match. Hanse's team member, Zeho, steps up to the challenge, but fails due to being too weak. However, Killua manages to defeat Bopobo, and the alliance members are then led to the pirates' lighthouse base outside the town. Razor, the leader of the pirates, challenges the group to a series of sports trials. The first is boxing, and Montreux steps up to the challenge.
When the rules are explained—one of them being that objects conjured with Nen are allowed—Hanse and Wong Li voice their disdain for the rule since they worry that conjured guns will be allowed, but they're assured by the pirate boxer that he will only use his fists. The match then begins, and Montreux looks like he has the upper hand and knocks down the pirate boxer, earning the praise of Yabibi and Hanse's teams, but Montreux suddenly falls down for the count as well. During the count, the pirate boxer gets back up and wins the match. It's learned that the pirate boxer used a teleporting uppercut to KO Montreux. The alliance team then loses the remaining matches. Realizing that there's no way for the Bombers to acquire the "Plot of Beach" card, the alliance is disbanded and the teams all leave the lighthouse (with the exception of Gon, Killua, Biscuit, and Goreinu).
Abilities & Powers
Gon's team estimated him to be too weak to defeat Razor's convicts, as turned out to be the case. Hanse was also unable to see the pirate boxer's teleporting uppercut.
Due to being able to access Greed Island, Hanse was capable of utilizing Nen.
