Uxie first appeared as one of the lake guardians in Pokémon Diamond and Pearl, the Sinnoh-region games where it watches over Lake Acuity alongside Mesprit and Azelf. Its distinctive cry was part of its in-game encounter, and it has carried over into later Pokémon titles that feature the lake trio. Online, fans reuse the short sound in reaction videos, Pokémon edits and nostalgia compilations because it instantly signals the Sinnoh legends, keeping a small piece of the original games alive in new content.
