Among all the moves in Pokémon, there is one that has been hidden from players since its inception. While there have always been moves that have been restricted to a few users, there is only one that has never been obtainable by normal circumstances. This creates an odd circumstance where a single move is rarer than even the most obscure Mythical Pokémon.
In Pokémon, every move is only available to a select amount of Pokémon. There are some that are widely available, such as Toxic, which could be learned by nearly every Pokémon in the original 151. At the other end of the spectrum are the signature moves of certain Pokémon. These are closely associated with a single Pokémon or family, and can often only be learned by them. Sometimes a Pokémon may not even be able to learn a move of their own type for one reason or another, and this move distribution is a big part of the games' intricate strategy.
Eternal Flower Floette Has One Of Pokémon's More Fearsome Signature Moves
In the data of Pokémon X and Y, there is information on a special version of Floette called Eternal Flower Floette. Eternal Flower Floette is significantly stronger than its original version and has a unique color palette, but cannot evolve into Florges. It also has its own signature move that normal Floettes cannot learn, Light of Ruin. Light of Ruin is a Fairy-type move with 140 base power, putting it on par with some of Pokémon's most powerful moves. However, it comes with a significant downside in that the user takes half of the damage they inflict with each use.
Light Of Ruin Cannot be Learned By Any Available Pokémon To Date
Despite how unique Eternal Flower Floette is, it has never been made legitimately obtainable in the games. There is no way to unlock it in X and Y, and it has never been distributed through any official events. It's a mystery as to why it has never been released, especially with the data in the game. Because Eternal Flower Floette was never released, Light of Ruin was never found in any Pokémon's moveset. The only way to see it in-game was for a Pokémon to use it via Metronome. Since Metronome chose from virtually every move in the game, this arguably made seeing Light of Ruin rarer than finding a Shiny Pokémon.
As unlikely as it seems, there is reason to believe that Light of Ruin may eventually make an appearance. Although several moves were removed in Pokémon Sword and Shield, with a few more missing from Scarlet and Violet, Light of Ruin has never been removed despite no Pokémon ever having an opportunity to learn it. This could mean that either Eternal Flower Floette may finally be released, or Light of Ruin may end up in another Pokémon's moveset. After existing solely through Metronome since its debut, it would be good to see Light of Ruin exist as a legitimate move. If Pokémon Scarlet and Violet release DLC, it could finally happen after four generations.
Light of Ruin holds an unusual place in the Pokémon universe, always present in the games, but with no Pokémon who are capable of learning it. It's disappointing, because both the effect and animation of the move are excellent. With any hope, Eternal Flower Floette and Light of Ruin may one day make their proper debut in a Pokémon game.
