I was watching a Japanese streamer play Gen 9 and they had one of their Pokémon use Double Kick. When I heard what the move was called in Japanese (にどげり/nidogeri), I had a thought...
Was the fact that the Nidos learned the move in Gen 1 a pun?
As an OG gen 1 player, them learning Double Kick has always felt a little iconic to me. It was moved to be an early move for the line in Yellow to compensate for Brock being a rather difficult matchup for Pikachu, giving it more exposure. The only other Pokémon to learn it in Gen 1 were Hitmonlee and Jolteon, so it wasn't a common move by any means. It's not a surefire theory but I think I like the idea.
