These guys were my least favorite enemy team during the Dark Tournament Saga of Yu Yu Hakusho

The team comprised mostly of three humans turned into slaves by an evil demon doctor. They spend most of the match beating up Kuwabara.

While the demon members of the team distract Kurama and Hiei.

Forcing them to not be able to fight in the match officially.

It all ends when Genkai uses the Spirit Wave technique to free the humans from their mind control devices.

It all seems to go well, the master of the human students is found and cured by Kurama.

The match isn’t really over when the officials call it. As Dr. Ichigaki injects himself with a serum to turn himself large and strong.

So Yusuke takes him out alone. And quite easily too.
