Story

Hyperdimension Neptunia mk2

Pirachu first appears in Chapter 2: The Crossroads of Defeat in Hyperdimension Neptunia mk2. He is found severely injured on the ground by Compa and is treated by her. Due to this event he immediately falls in love with her only to have his heartbroken when she says she hates her enemies after he reveals being part of AISC. 

Pirachu, along with Linda, is the direct cause for the majority of problems that hinder Nepgear and her party as they try to rescue the CPUs and save Gamindustri. While Pirachu is sometimes seen alone, he is mostly together with Linda, causing trouble for the party in some way or form such as when they damaged the ship to prevent Nepgear and the others from going to Leanbox and even kidnapping and holding Chika hostage while Linda pretended to be her.

Towards the end of the game, he decides to follow Linda to the end in her attempt to redeem herself one final time against Nepgear and her party. When they are defeated, he stays with Linda regardless of what may or may not happen when the CPUs face off against Arfoire. In the True Ending, Pirachu is seen distributing Arfoire chips with Linda, even though they don't work. When caught by Nisa and Gust, the two make a run for it.

Hyperdimension Neptunia Victory

In Hyperdimension Neptunia Victory, Pirachu appears in the Ultradimension as a member of the Seven Sages. He is first seen together with Arfoire, collecting CPU Memories. When approached by Neptune and Noire, Arfoire hands the CPU Memories over to Pirachu so he can escape while she takes care of them. When Pirachu runs away, Plutia goes after him and ends up transforming, taking the CPU Memories from him by force as well as traumatizing him entirely. Pirachu takes place in a number of events regarding the Seven Sages such as Mr. Badd's takeover of Lowee, tricking the CPUs into believing that Blanc was working with the Seven Sages, and even the kidnapping of IF, Compa, and Peashy as children. He also helps Arfoire escape when she kidnaps IF to get to Neptune. 

At the end of the game during True End, Pirachu joins the newly reformed Seven Sages who work to benefit and help the CPUs while also working for Arfoire on her eggplant farm.
