A male Tusken Raider, KkH’Oar’Rrhr was born on the suns-scorched planet of Tatooine, in the last years of the Galactic Republic. He was keenly attuned to the Force, a mystical energy field that bound the galaxy together and gave special powers to those who knew how to wield it. He belonged to the Rrhr hunting band, one of the many Tusken clans that dwelled in Tatooine’s sweeping expanses of wilderness. In 22 BBY, the Rrhr clan captured a Human named Shmi Skywalker Lars. Soon thereafter, the Jedi Knight Anakin Skywalker came to rescue his captive mother and, upon seeing her dying in his arms, ended up slaughtering the whole village in a fit of rage. Hoar was the sole survivor of the carnage, because he had been away bonding with his bantha at the time. Following that traumatic event, KkH’Oar’Rrhr was adopted into a clan led by A’Sharad Hett, a Human-born Tusken leader.

A’Sharad Hett discovered the Force-sensitivity of KkH’Oar’Rrhr. Hett had once been a Jedi himself, and he decided to train Hoar as his successor. The young Tusken was taught how to channel his aggression through the Teräs Käsi martial art, and was also taught the rudiments of Galactic Basic Standard. KkH’Oar’Rrhr was also given a special, bisected gaderffii stick, and was trained in dual-weapon fighting. As KkH’Oar’Rrhr grew stronger, he became the idol of the younger Raiders.

Circumstances taking him offworld, KkH’Oar’Rrh came into conflict with Arden Lyn. Her abilities in Teräs Käsi, however, overpowered that of KkH’Oar’Rrhr’s formidable fighting abilities. Despite being defeated, he was later recruited into Lyn’s school of Teräs Käsi after he surprised the latter with his knowledge on her martial art, and was promised to make him more powerful than he imagined. Seeing the opportunity to get stronger, he left the Grave Tuskens behind and trained under her. Armed with the traditional Tusken weapon, the gaderffii, Hoar became a student of Arden Lyn. With her guidance, he honed his fighting skills and mastery of Teräs Käsi. In hand-to-hand combat, Hoar wore the traditional Tusken battle mask that included long, metal pieces protruding from both sides of the jaw to protect the throat from direct attack. He eventually channeled his own Force abilities into Teräs Käsi, becoming a destructive whirlwind.
