Boule Brothers (anime)

The Boule Brothers worked as droids for the Black Moon Clan. These are the first animated depictions of the original manga characters.

Biography
In the anime, Achiral and Chiral were droids belonging to Esmeraude. They are summoned by Esmeraude to attack Negative Points in order to open the Dark Gate. Chiral is to corrupt Juuban Elementary School, while his brother Achiral is to corrupt Juuban Park. Sailor Moon arrives on the scene, and is quickly confronted by Chiral. Achiral joins his twin, and is prevented from harming young Chibiusa due to Sailor Mercury's Sabão Spray attack. Achiral creates his own diversion by sending the possessed Momoko Momohara after the senshi, and Chiral takes the opportunity to disappear and reappear behind Sailor Jupiter, taking her by surprise.

Chibiusa uses her own energy to release Momoko from the droids' control, and blasts the droids. Sailor Moon, Sailor Mars, and Sailor Jupiter run into the schoolyard after Achiral and Chiral, who try to ambush the girls from behind. They are prevented from doing so by Tuxedo Mask. They then attempt to escape by phasing through the ground, but Sailor Jupiter stuns them with her Sparkling Wide Pressure attack long enough for Sailor Moon to destroy them with Moon Princess Halation.

Trivia

 * Unlike all the other Droids, Achiral and Chiral are strikingly different. They more closely resemble members of the Black Moon Clan, with the symbol of the upside-down dark crescent moon on their foreheads. They also didn't die like other Droids generally did, but exploded rather than crumbling into particles. Plus all the other Driods are female and they are male and they usually attack on their own.
