Pokémon that changed type
A Pokémon's type feels permanent, but the games have quietly rewritten a handful of them over the years. When a new type is introduced, older Pokémon are sometimes reclassified to fit it. Twenty-three Pokémon have had their typing changed this way, and knowing which ones is a genuine edge when you play a guessing game that respects the original rules. This guide walks through every change and why rayquizz treats type as something that depends on the generation you are playing.
Generation 2: the Magnemite line gains Steel
The Steel type arrived in Generation 2, and two Pokémon were reclassified to use it. Magnemite and Magneton, pure Electric in the original games, both became Electric and Steel. It is an easy change to forget because their appearance never changed, only the rules underneath them. In an early-era game they defend and resist like pure Electric types; from Generation 2 onward they carry Steel's long list of resistances.
Generation 6: the Fairy wave
The biggest shake-up came with the Fairy type in Generation 6, introduced partly to rein in the dominant Dragon type. Twenty-one existing Pokémon were reclassified to Fairy in one stroke. Some became pure Fairy, like Clefairy, Clefable, Cleffa, Snubbull, Granbull, and Togepi, all of them Normal types before. Others gained Fairy as a second type: Jigglypuff, Wigglytuff, Igglybuff, and Azurill became Normal and Fairy, Marill and Azumarill became Water and Fairy, and the entire Ralts line, Mr. Mime, and Mime Jr. added Fairy to their Psychic. Mawile, once pure Steel, became Steel and Fairy, while Cottonee and Whimsicott turned Grass and Fairy. Even Togetic shifted from Normal and Flying to Fairy and Flying.
Why this matters when you guess
Most Pokémon sites only show a Pokémon's current type. rayquizz does something different: it judges type by the era you select. If your generation range ends before Generation 6, Clefairy is scored as a pure Normal type, exactly as it was in the early handhelds, and a Normal-type guess counts as a correct match. Set the range to include Generation 6 or later and the same guess is wrong, because Clefairy is now Fairy. The Magnemite line behaves the same way around the Generation 2 boundary. This is not a bug or a quirk, it is the point: the game stays faithful to the era you grew up with.
The short version
Two Pokémon changed in Generation 2 (Magnemite and Magneton, gaining Steel) and twenty-one changed in Generation 6 (the Fairy reclassifications). If a type clue ever looks wrong, check your generation range first. It is almost always one of these twenty-three at work.
