A series of five surveys, four with extremely large sample sizes - more than one million have taken the Generation I recognition quiz on Sporcle, have effectively pegged the least recognisable Pokémons. Generation V has been taken 1,976 times, the least of all five. But according to the results, these are the five most-forgotten Pokémons across all five generations, in descending order:
Generation I: Marowak, 36.7 percent; Kingler, 35.4 percent; Lickitung, 33.7 percent; Exeggcute, 31.4 percent; Exeggutor, 31.1 percent.
Generation II: Slugma, 37.1 percent; Shuckle, 35.9 percent; Magcargo, 34.3 percent; Qwilfish, 34 percent; Corsola, 33.9 percent.
Generation III: Chimecho, 41.3 percent; Crawdaunt, 41.1 percent; Corphish, 41.1 percent; Whiscash;, 39.2 percent; Barboach, 38.8 percent.
Generation IV: Finneon, 38.1 percent; Lumineon, 37.9 percent; Chingling, 37.4 percent; Chatot, 37.1 percent; Mantyke, 36 percent.
Generation V: Accelgor, 20.6 percent; Stunfisk, 20.5 percent; Elgyem, 17.7 percent; Amoonguss, 16.6 percent; Beheeyem, 15.6 percent.
Accounting for Generation V's low scores being because the game is so new in the West, it's still pretty good when your least recognisable characters are still recognised by 300,000 out of a million people.
It's also a little funny that Exeggutor is the least recognised out of the oldest generation. Tsunekazu Ishihara, president and CEO of The Pokémon Company, said in 2000 that Exeggutor was his favorite. "That's because I was always using this character while I was debugging the program."
