A masterful martial artist who is much admired by Garu, he appears in the episodes 'Autograph This!s' and 'Invincible Vengeance' as a central character. Although Hiel possesses superhuman martial arts abilities (even beyond those of Garu), Pucca has always managed to overcome him. He also happens to be one of the legendary Fire Wasp Ninjas. His name is a pun on the phrase 'he'll kick you'. As shown on the few occasions where Hiel has a speaking role, he loves money and is not above teaching people skills for money, even if they cannot use them properly.
