Garoben was a Youma summoned by Jadeite to drain energy from unsuspecting students as part of the Dark Kingdom's continuing energy-gathering efforts. She appeared in anime episode 8. She was a female humanoid creature with red skin, dark spiky hair, a light purple mark on her forehead, and spikes that stretched from her shoulders and back.
She was in charge of the Crystal Seminar, a cram school that Ami attended. The students were given special disks to use, not knowing that the disk would activate a program that would drain their energy. Usagi discovered the disk after a new student, Ami, left hers behind. Suspecting Ami to be from the Dark Kingdom, Usagi disguised herself and infiltrated the school.
Usagi confronted Ami and transformed into Sailor Moon, but then Garoben appeared, grabbing Ami by the neck and taking her hostage before transforming into her Youma form. While holding Ami, she first puzzled Sailor Moon with physics questions before sending dozens of razor-sharp test sheets at her. Sailor Moon managed to dodge them, but ended up in a corner. Garoben asked if she wanted to surrender now or later, before the hypnotized, energy-drained students began surrounding Sailor Moon.
While Sailor Moon was busy fending off the students, Garoben forced Ami to look at her computer screen in an attempt to drain her energy, only to find it ineffective. Garoben threw her to the ground, and morphed her left hand into a large axe. After managing to dodge the first swing of the axe, Ami transformed into Sailor Mercury. Garoben wound up for another strike, but became lost in the cold mist created by Mercury's bubble attack. As she began shivering, the hypnotized students collapsed, freeing Sailor Moon and allowing her to use her tiara to destroy Garoben.
In the game Sailor Moon S: Quiz Taiketsu! Sailor Power Ketsushuu, Garoben was one of the monsters revived by the Daimon Quiz in order to fight the Sailor Senshi.
- Originally, Garoben asked Sailor Moon a question on why apples fall from trees, referring to Isaac Newton's theory on gravity. Her second question was to explain what gravity was in less than 50 words. In the English dub, she first asked a math equation and then asked if Sailor Moon wanted to surrender.
