As we all know Gamefreak does not only make Pokémon games but also other pretty fun games with the most well-known being Pulseman, Drill Dozer, and the recently released HarmoKnight. Taking a further look at these games we can see that Gamefreak loves to reference aspects of Pokémon within these games and reference aspects of these games within Pokémon. The most notable are:
-Pulseman's signature attack Volt Tackle becoming the signature move of the Pikachu-line as well and
-the designs of the Excadrill-line and the Klinklang-line taking inspiration from Drill Dozer.
Basically with this thread I'm hoping to find other cross-references between Gamefreak's games.
I believe I've already found a small one today while playing HarmoKnight: the cactus maracas and Maractus.
Who knows? Taking into account the Excadrill-line's and the Klinklang-line's design inspirations we may even find ideas for and clues to future Pokémon!
