Sailors Uranus, Neptune, Pluto and Saturn are the Outer Guardians, who protect the solar system from alien threats. Without any aliens threatening the Earth in the six months following their first battle, the Outer Guardians simply carried on with their usual lives.
Weapons
Unlike the Inner Sailor Guardians, each of the Outer Sailor Guardians fight with a special weapon; Uranus, Neptune, and Pluto each bear one of the three Talismans (the Space Sword, the Deep Aqua Mirror, and the Garnet Orb respectively), while Sailor Saturn wields the Silence Glaive. Depending on the medium, the Outer Sailor Guardians may already be in possession of these weapons when they are first introduced, or may acquire them later.
Relation to the Inner Sailor Guardians
In civilian form, the Outer Sailor Guardians appear charming and personable, but their relationship to the original Sailor Team as Guardians varies depending on the medium (anime, manga, ect...) and specific story lines. In the beginning, the two teams usually have a mutually strong aversion to each other, forcing Usagi, Mamoru or Setsuna to act as mediators. While they demonstrate extreme dedication to their roles as soldiers, the Outer Sailor Guardians can be aloof, and are willing to forego heroic behavior and make ruthless choices for the greater good. They can also be ambivalent towards the Inner Sailor Guardians if they think conflict will arise from attempted co-operation, or as a mishandled way of protecting others. In all incarnations, the question of how to handle the potentially dangerous Sailor Guardian, Sailor Saturn formed the largest conflict of interest between both groups. Eventually, more is learned of the Outer Sailor Guardians' history during the Silver Millenium and the two teams mutually accept each other.
