Purr4s (ヨンネコ, Yon'neko) are blue catlike monsters exclusive to Hyperdimension Neptunia Re;Birth1.
Purr4s have 4 skills:
Purr4s don't seem to have a very specific Attack Pattern, since they use Attack, Virus Attack and Power Support almost the same amount of times. Explosion is the only skill who breaks this, since Purr4s seem to rarely use this skill.
Purr4s don't have direct partners.
- They're based on the PlayStation 4, this can be appreciated in their color, shape and name. They are blue, the color that represents Sony along with black, they are shaped like a PlayStation, and they're called Purr"4", meaning that they're based on the 4th home PlayStation.
- They are the first monsters to not directly appear in the map, but rather, being found as partners of other monsters.
