Techniclon is one of the Seven Shadows. She can fire missile capsules containing leeches and catch attacks inside a test tube to reflect them back at her opponents. She appeared in Sailor Moon Episode 25, Too Many Girlfriends.
After she was imprisoned in the atmosphere, she was reborn inside Rita, one of the crystal carriers. Zoycite extracted the crystal and turned Rita into Techniclon. She fought the Sailor Scouts, reflecting Sailor Jupiter's attack at Sailor Moon and Sailor Mercury, but was eventually healed by Sailor Moon using Moon Healing Activation, killing Techniclon while healing Rita unharmed.
