Warechu (ワレチュー, Warechu), previously known as Pirachu in the English version, is a recurring antagonist in the Hyperdimension Neptunia series. Due to the Neptunia series being a game that revolves around different universes and dimensions, there are multiple Warechu's throughout the series, though they more or less have the same personalities.
Hyper Dimension Warechu
A proud member of the Arfoire Syndicate of International Crime (ASIC), Warechu frequently is seen doing the organization's dirty work alongside Underling. Though opposed to Nepgear and her party, Warechu is smitten with Compa due to her tending to his injuries.

His original Japanese name, which is retained in Idea Factory International-translated titles, is a pun on 割れ厨 (same pronunciation) which literally means a (software) pirate. Chu (チュー) is also a sound of a mouse/rat in Japanese. In English, his name can also be seen as a reference to the term "warez".
Warechu's NIS America-translated name "Pirachu" is a reference to Pikachu. But the "Pira" may come from "Pirate", which is the act of illegally copying a game, movie, or any sort of licensed media.
- Warechu is one of the few characters lacking a physical change between games.
- Though he does not appear as a character, several variations of "Pirachu" can be found as dangerous foes in Hyperdimension Neptunia Re;Birth1 dungeons.
- In ending credit scenes, Warechu is often portrayed as a gigantic, bestialic-looking monster; sometimes he is even serving as the final boss.
- When Kurome mutated Warechu, he resembled the form found in the credits.
