1st-Gen Compa (初代コンパ, Shodai Konpa) is a Maker based on the no longer existent company Compile. Due to the Neptunia series being a game that revolves around different universes and dimensions, there are multiple 1st-Gen Compa's throughout the series, though they generally have the same appearance and personality traits.
- Shake-ko incorrectly refers to 1st-Gen Compa from the Ultra Dimension as a male when she tells you about the time that 1st-Gen Compa saved her from a dungeon. This is most likely a translation error.
- According to the Hyperdimension Neptunia: Megami Tsuushin manga, 1st-Gen Compa is indeed related to Compa, but it's not clarified how.
