Team Toguro
Team Toguro are the primary antagonists of the Dark Tournament saga. They managed to reach the final round of the Dark Tournament, but lost to Team Urameshi.
Sakyo * Seiyu: Nobuyuki Furuta
Sakyo is the wealthy owner and leader of Team Toguro and a member of the Black Book Club. Sakyo's main interest is gambling, and is usually a very calm, collected, and intelligent person while keeping his evil side influencing his outside self. Sakyo became very wealthy quickly by threatening to wager his life while gambling, leading most to quit, and eventually joined the Black Book Club. Sakyo, should Team Toguro win the Dark Tournament, had planned out everything perfectly: as a team member he would be given one wish, and as leader be given most of the Tournament's finances, allowing him to help further the BBC's plans. Sakyo wagered his life during the final battle, and after his team loses, Sakyo set a self destruct button in the arena, crumbling everything around him, including himself. In the anime, Sakyo has a romantic relationship of sorts with Shizuru, Kuwabara's older sister.
Younger Toguro * Seiyu: Tesshō Genda
* Voice Actor: Dameon Clarke
Younger Toguro is the younger brother of Elder Toguro, though is stronger than his elder brother. Always calm and collected, Toguro has always had emptiness in his heart, though attempts to fill this with power. Younger Toguro was a teammate of Genkai's in the Dark Tournament fifty years prior to the series, joining to kill a demon who slaughtered his disciples, and after emerging as victor, Younger Toguro wished to become a demon. As a demon, Younger Toguro's main ability is muscle manipulation, and he names his power levels by percentages. When at 100%, Younger Toguro must devour the souls of those nearby to keep his almost indestructible body energized. In the end, however, Younger Toguro was only looking for a stronger opponent to defeat him, which comes in the form of Yusuke Urameshi, and died thanking Yusuke. In the afterlife, Younger Toguro asked to be sent to the last circle of hell, which is 10,000 years of torture for 10,000 cycles until the soul ceases to exist. In the second popularity poll, Younger Toguro ranked at 10th place with 447 votes.
Elder Toguro * Seiyu: Katsumi Suzuki
Elder Toguro is Younger Toguro's unpleasant and sadistic midget elder brother, and usually rides on his brother's shoulder. He fought alongside his younger brother in the Dark Tournament 50 years before the series, and wished to be a demon after their team's victory. Elder Toguro can alter the shape of his body to form weapons out of his body parts or move organs to escape harm, and also has powerful regenerative abilities, almost to the point of immortality. He fought and lost to Kuwabara in the final rounds of the Dark Tournament, and was kicked off the island by his disgusted younger brother. Elder Toguro's remains were found by Sensui, and took over Makihara's body. Kurama, however, then attached a cursed tree to Makihara's body that would drain Elder Toguro's energy until death, though his immortality would backfire and bring him eternal pain. In the second popularity poll, Elder Toguro ranked at 11th place with 421 votes.
Karasu * Seiyu: Ryō Horikawa
* Voice Actor: Kyle Hebert
Karasu was defeated by the Toguro brothers several years before the series, and he followed them when promised a rematch. Raven-haired Karasu is always calm and serious, yet sometimes quite sadistic. Karasu can create explosives, and can even use his spirit energy to explode objects without contact. After taking off his lower facial mask, Karasu's hair turns blond, and he can use a powerful full-body explosion. Karasu also gained a crush of sorts of Kurama, wishing to gain his severed head. Karasu, however, gets killed by a demon fox Kurama during the final round. In the second popularity polls, Karasu made 8th place with 698 votes, making him the most popular of Team Toguro.
Bui * Seiyu: Tetsuo Kaneo
* Voice Actor: Vic Mignogna
Bui, like Karasu, was defeated by the Toguro brothers and followed them when promised a rematch. Bui is easily defined by his heavy armor, which is used to contain his gigantic strength increasing aura, and an axe larger than he is. Bui fought and lost to Hiei in the final round.
