>>16648077Kecleon was intended to be one, too. Note how there was no new eeveelution in gen III and how Kecleon's name ends like all the other evolutions. Not to mention Kecleon adapts to things by changing type, similar to Eevee.
Empoleon and Lumineon were also intended to be eeveelutions, but were replaced at the last minute by Leafeon and Glaceon because somebody remembered Vaporeon existed and realized we didn't need three different water type evolutions for Eevee. But they almost went through with it anyway because GF loves water types so fucking much.
