Sailor Aluminum Seiren from "Sailor Moon" by Bill Dinh

Aluminum Seiren was part of the last sub-boss squad shown in Sailor Moon, the Sailor Animamates. In the manga, they were women who killed the Sailor Soldiers of their home planets in order to get power from Sailor Galaxia. They'd then work for her in the hopes that they would be given the power of a true Sailor Soldier and a planet of their own. Seiren came from the planet Mermaid, could manipulate ice and songs, and KILLED Sailor Mercury and Sailor Jupiter.

In the anime, Seiren was possibly a good Sailor Soldier brainwashed into working for Galaxia. She was very polite and somewhat ditzy, to the point that she'd hand out business cards to introduce herself to her enemies. Arguably, she was the nicest villain who didn't turn good or wasn't a backstabber. When she was in battle, she was a nightmare.

Bill didn't charge me for this because apparently something was wrong with the paper.
