Paimon is a non-playable character in Genshin Impact and accompanies the Traveler throughout their adventure in Teyvat as their guide. She met the Traveler by being fished out of a lake in which she mentions she would've drowned if not being fished out. She is currently representing Genshin Impact as its mascot and is on the Genshin Impact app, website, Twitter and social media icons.
Paimon is bubbly, out-going, but almost a little too honest, somewhat naïve and occasionally comes off as rude. She makes it clear who she favors; who she likes and who she doesn't like, for example as she does not like Venti, she makes it quite clear by calling him "Tone-deaf bard". She stands by what she thinks and makes it quite clear. She tends to refer to herself in the third-person point of view.
She loves eating; despite her small size, she can wolf down large amounts of food before feeling full. She is also well versed in the history behind many dishes. While she enjoys slime products, she also states that her worst nightmare is being eaten by a particularly large slime.
Paimon has a small body, giving her the look of a fairy. She has thick white hair cropped just above her shoulders, dark purple eyes, and fair skin.
She wears a long-sleeved white jumper and a night-blue cape flecked with stars, and white stockings with white boots. Rose-gold embroidery and shapes are attached to her jumper, boots, and sleeves.
Paimon's accessories are a dark purple hairpin, almost black, and a rose-gold crown that levitates above her head as though it was a halo.
- During the Closed Beta Tests, Paimon was used as a spokesperson, replying to the questions and suggestions that were asked on the official Facebook page.
- It is hinted that she cannot swim, though when swimming in-game in water, she floats above you just over the water.
- Paimon's nickname within much of the Genshin Impact community is "Emergency Food." This comes from one of the dialogue options when the Traveler first meets Amber in the Prologue quest Wind-Riding Knight.
- Paimon's role as the mascot of Genshin Impact is similar to Ai-Chan, the mascot for Honkai Impact 3rd, another of miHoYo's games.
- The Traveler's voice lines suggest that Paimon has more than one stomach, where one of them is made specifically for liquids.
- Verr Goldet, the boss of the Wangshu Inn, describes Paimon as a "floating elf companion." Notably, she is one of the few characters who remarks on Paimon's appearance.
- The symbol on Paimon's clothing is an upside-down triquetra, one of the prominent symbols in Teyvat. She also bears the Celestial motif on her sleeves and boots.
- Paimon's headpiece shares design elements with a fully-upgraded Statue of The Seven. The ring that forms around the statue at Level 10 has the same design as the ring that forms the base of her headpiece, while the vertical protrusion on her headpiece is a simplified version of the diamond-shaped leaf motif that appears upon upgrading the statue to Level 6.
- Paimon represents some parts of the gameplay system in Genshin Impact.
- In the demonology grimoire The Lesser Key of Solomon, "Paimon" is one of the nine kings of Hell.
