First guardian

A first guardian is an entity that exists to protect its planet and "facilitate the planet's ultimate purpose". First guardians are typically almost as old as the planets they are born on, and they are born through Weird Plot Shit and Weird Time Shit. Every planet destined for intelligent life has such a guardian, and though their forms vary widely, they all share a common and potent genetic code. This code grants them near omnipotence, and they can be "merged with a host of great intelligence", granting them near omniscience as well. is Alternia's first guardian, Becquerel is pre-scratch Earth's first guardian, and the God Cat is post-scratch Earth's first guardian. Pre-scratch Alternia had a different first guardian as well, but they have yet to make an appearance in the story. If current trends are indicative, first guardians have a unique "green energy" effect, in which they appear to flicker and flash with a green electricity, appearing to shift in and out of existence and generally radiate energy. Another object with similar properties is the Green Sun, the source of the first guardians' powers.

It seems their ultimate purpose is to help complete stable time loops, in order to have the game developed and played. Becquerel demonstrates this when he HS 3033 (leads) Jade to John's present, allowing them to meet in the first place. manipulates the trolls through Vriska, and at one point uses her to orchestrate the death of Aradia. He finds Aradia much more convenient to manipulate, controlling her into tricking Sollux into developing the game, and presumably also controlling a number of events within their session.

A secondary purpose of first guardians is to ensure their own existence through stable time loops. Bec influenced his own creation by protecting Jade and taking her to John's note, though most of his creation was facilitated by others such as Jack Noir and the trolls. brought about his own existence as well.

In addition to (or possibly as part of) his duties regarding Sgrub, is working to ensure 's entry into the Alternian universe. It's possible that every first guardian works for, though it's more likely 's situation is unique. He contacts Rose and supplies her with information, seemingly in order to destroy the Green Sun and kill himself.

After the scratch, Earth's first guardian appears to be the mysterious God Cat, a feline living in Jane Crocker's neighborhood. The cat saved Jane from the letter bomb left for her by the Batterwitch by teleporting her away. God Cat's genetic origin may potentially have something to do with Jaspers and/or Mutie.
