>“The original concept was to create a Pokémon family that starts as a flame, then a candle, and finally a lamp. But the idea that a flame evolved into a candle wasn’t really working, so we ended up switching the candle’s position to make it the family’s first form.”
So the original idea was that Litwick would be the middle stage and Lampent would be the last stage, before they scrapped it and made Chandelure as the last stage instead
