Boule Brothers  

Chiral and Achiral, Doom and Gloom, キラル / アキラル

The Boule Brothers are two minor antagonists in the Black Moon Clan who appear in both the manga and anime versions of Sailor Moon. While they have a more significant role in the manga plot, where they greet the Sailor Senshi upon their arrival in Crystal Tokyo and create a mirror-image replica of the palace as a trap, they are simply monsters of the day in the anime. In both versions, the brothers are under Green Esmeraude's service and appear on her page in the Materials Collection art book. The Boule Brothers are killed by Tuxedo Mask and Sailor Venus in the manga, while in the anime they are used to grow "Dark Henges" at Juuban Park and Juuban Elementary School, causing all pupils and teachers to fight each other viciously. Additionally, in the anime version, the brothers attack Chibiusa's best friend, Momoko, which causes Chibiusa to reveal her identity as "The Rabbit" to the Black Moon Clan.
