U-Pasokon was a Daimon supervised by Mimete, who attacked Sergei Asimov for his Pure Heart Crystal. She was created from the fusion of a Daimon Egg and a computer, and as such had a computer monitor in her torso and computer mice on her shoulders. She also attacked by throwing computer mice, which turned into vicious rats in mid-air, and by hurling razor-edged computer disks.
Although she managed to hold her own for a short time in a battle against the Inner Senshi, she was taken by surprise by Sailor Chibi Moon's Pink Sugar Heart Attack and distracted long enough for Super Sailor Moon to finish her off with Rainbow Moon Heartache.
U-Pasokon was one of the "cormorant" style Daimons, which attacked by sucking out the target's Pure Heart Crystal and storing it in their throats until they could return it to Professor Tomoe. However, she never managed to remove her target's Heart Crystal, as the Sailor Senshi arrived and Mimete ordered her to attack them instead.
- "Pasokon" is a Japanese abbreviation for "personal computer."
