Neptune (ネプテューヌ Neputūnu) is a CPU from the Hyperdimension Neptunia franchise, who personifies a fictional game console (but whose name may be inspired by the prototype Sega Neptune). She transforms into the Goddess Purple Heart (パープルハート Pāpuru Hāto), and in one game has a third Next Purple (ネクストパープル Nekusuto Pāpuru) transformation. She is set to be featured in the PlayStation Vita game Chou Jigen Taisen Neptune vs Sega Hard Girls - Yume no Gattai Special (in which she is at some point trapped in a "Nepbike" form), alongside her SeHa Girls counterpart Sega Saturn.
