A Ludiv is a type of fairy found in Rayman's world, most notably in the PlayStation version of Rayman 2, where Rayman must free them from cages, along with Denys and Greenbottles. It is said that they are short-sighted and that they wear glasses – that without them, they end up stuck, lost and knocked to the ground.
A Ludiv (referred to only as a "pretty little fairy") appears in the bonus stages unlocked at the end of each level in Rayman 2 by finding all the level's Lums and breaking all its cages. In these bonus stages, the player controls a Baby Globox, which must race against the Spyglass Pirate to get to the Ludiv first. If the player wins the race, the Ludiv can grant Rayman gifts (health and/or Power Fists). In the PlayStation version of the game, Ludivs are imprisoned in cages by the Robo-Pirates, along with greenbottles and Denys. When Rayman frees Ludivs, hearts appear over their heads in a manner which recalls the Electoons from the previous game.
In Rayman Collector, three of the minigames (feu nourri, multiplication des pains and le bouingue) are made by a company called Ludifactory. A company named Ludimedia developed the PlayStation version of the original game. Ubisoft may have named Ludivs after these companies as an in-joke.
