Machine is a recurring enemy type in the Hyperdimension Neptunia series. Enemies under this type have been present since the first Hyperdimension Neptunia but no proper name was established until Hyperdimension Neptunia Victory. As the name implies enemies under this type are all machine-based, typically robots.



Machine enemies typically have an innate resistance to physical attacks. This means that, unless a character has the "Ignore Category" trait, magical attacks are more effective when combating them.


Various types of machines can be encountered:

  • BitBit Custom.png: Small orb-like machines with an antenna shaped like a bowtie.
  • MediaR-4.png: Saucer like machines, with a single yellowish "eye" and a spiked circular ring in the back. Generally named after various kind of flash media.
  • TankR4i-SDHC.png: Squat, four-legged machines with two energy cannons in front.
  • KillachinesKillachine.png: Immense hovering robots wielding an axe and a mace. These almost always appear as bosses or dangerous enemies.
  • HeroboHerobo.png: Large winged mecha. Like Killachines, they are usually bosses or dangerous enemies.

A number of antagonists, such as CFW Judge, CFW Brave, Copypaste, Mister Badd, and Anonydeath, are also classified as machine-type enemies when encountered as bosses.

  • There are two groups of machines named after flash cards, which are used to play pirated games. The most well known flash card is the R4, but in spite of this, R-4 and R4i-SDHC are the weakest of their respective groups.
