Was Arcanine originally intended to be a Legendary Pokemon? If not then why was it on this Mural that Ash saw on the 2nd episode..
Well if you look at the Beta designs and some of the early tcg cards along with its Pokedex entry it seems it was originally intended to be, also its design and lore are based on East Asian mythological guardian creatures..
So what changed? Maybe it was originally intended to be part of the bird-beast Trio and then swapped for Moltres (Moltres was reportedly added late) because 3 birds just made more sense.. or they nerfed it not wanting it to be to much stronger than say Charizard who was going to be a big part of Ash's journey and on the box cover of Red Version, while Gary had Arcanine in the Anime.
So why not a Pseudo? I Honestly still consider it one "in spirit" but its stats do fall short of the 600 at 555 total, so I think they nerfed it some to fit the anime/games better, remember Gary had one and it would have been too overpowered to give him a Legendary, and They already had a Pseudo in Dragonite so they gave it a evolution and called it a day I guess. Either way I think it all worked out.
