Giwaaku is a Droid of the Black Moon Clan, deployed by Esmeraude to poison one of Earth's weak points with dark energy. Her assignment centers on Sailor Mercury, aiming to turn the blue Guardian against her own friends through illusions of betrayal.
Giwaaku's defining physical feature is the pair of antennas she uses to project her illusions. She can also split into several copies of herself, crowding a space with duplicates that wink out the instant they are struck.
True to her name, which comes from a Japanese word for doubt or distrust, she works through deception rather than direct force. The DiC English dub leaned into the theme by renaming her Mistrust.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Esmeraude plants Giwaaku at a soft spot inside Ami's school, and the droid's influence spreads until the whole campus turns on Ami and brands her a cheater. Ami tracks down the culprit and transforms into Sailor Mercury to confront her. Giwaaku swarms her with clones, then makes her hallucinate that the arriving Guardians have betrayed her. The trick barely dents Sailor Moon, who is used to fielding insults, though the clones do manage to hurl Tuxedo Mask through a window. In the end the bond between the friends proves stronger than any illusion: Sailor Mercury shatters the droid's antennas with Shine Aqua Illusion, and Sailor Moon finishes Giwaaku with Moon Princess Halation.
