Saturn

Shunsho Ryan Love (codenamed "Saturn") is from Sandgem Town in the Sinnoh region. He's a former member of Team Galactic and is currently a member of the Tekiyoku. He's a Fairy Manipulator, although his contract Pokémon is unknown.

Pre-Series
Saturn was first seen in the Transmissions, namely the 3rd one, where he revealed he's a Fairy Manipulator (which is canon), but the general happenings in the Transmissions aren't canon to the series.

Present
Saturn hasn't been seen in a fight with the Mokusetsu yet. He was only seen early in the series with his fellow former Team Galactic members, Mars and Jupiter, discussing general Tekiyoku plans with Giovanni.

Mars revealed that she and Jupiter would remain in Sinnoh to be stationed with Annie, Oakley, and 4 other members, later revealed to be Zero, Kagetomo Koyama, Argus Steele, and Pierce Itoh. Saturn said he'll be sent to Hoenn with 6 other members.

Naming

 * His three names, Shunsho, Ryan, and Love were all randomly selected from name generators, the first name being from a Japanese name generator and the second two from an English one.
 * His codename, Saturn, is what he's referred to in both the Japanese and English versions of the Pokémon anime. This is his actual name in the anime. Nocturnal Jay decided to have it be a codename. The name simply comes from the planet, Saturn. He shares this name scheme with Jupiter and Mars.

General

 * His birthday, November 10th, is the United States air date of the episode of the Pokémon anime he first appeared in.
