Unlikely Pokémon Winds & Waves monster hides 20 years of history

Pokémon archivists just released footage of a never-before-seen documentary about the making of 2007's Pokémon Diamond and Pokémon Pearl , and it's proven to be a treasure trove of trivia for hardcore fans. There's an inside look at how Game Freak develops starters, early Pokémon designs for some of the most iconic characters, and surprisingly, tidbits that shed light on modern Pokémon games. Developers at Game Freak came up with ideas 20 years ago that did not see the light of day until the release of Pokémon Pokopia .

And the idea might reappear when Pokémon Winds and Waves is released next year.
