Riehlvelt is one of the three fighters who challenge Gon and Killua on the 200th floor of Heavens Arena. Riehlvelt has a ruthless personality, resorting even to kidnapping and blackmailing to get his way. He is intent on becoming a Floor Master in order to live off the money and fame of the rank despite lacking the necessary strength, for which reason he only fights opponents weaker than himself. He was nonetheless brave enough to face Killua in combat despite the ease with which the former assassin threatened him. He seems to have a sadistic side as well, bursting into laughter when electrocuting his opponent. However, when faced with the prospect of being electrocuted, he passed out from the fear of it. At some point in his life, Riehlvelt reached the 200th floor of the Heavens Arena without knowing Nen. He was thus "initiated" by an opponent whose malicious aura attack paralyzed him from the waist down. Prior to fighting Gon and Killua, he totalized five wins and two losses. None of his opponents ever succeeded in catching his whips.
