star seed (sailor moon)

An important object only seen in the last story arc of Bishoujo Senshi Sailor Moon. A small diamond-shaped crystal (technically a hexagonal dipyramid) surrounded by a circular glow. According to the series' lore, every living entity throughout the universe has a Star Seed, commonly depicted with a pale white color. Planetary guardians possess True Star Seeds that are colored according to each planet's theme color, such as with the Sailor Senshi, as well as Chiba Mamoru since he is Earth's guardian.

Sailor Galaxia's goal is to collect all of the Star Seeds in the universe so she can become the strongest Sailor Senshi in existence.
