Given that fans have been pondering this question for a very long time it was instantly joked how they were Leaning on the Fourth Wall addressing Pokémon logic in-universe. 'After 23 years they start getting too self-aware?' Explanation The Journeys anime has Goh and Ash wondering why Dratini and Dragonair are blue and serpentine, but Dragonite is orange and bipedal and looks nothing like its pre-evolutions, with Gou even suggesting that Milotic would have made a more logical-looking final evolution.Explanation Due to Gardevoir, a human-like Pokémon, being in the Amorphorus Egg Group, it's able to breed with Pokémon such as Muk, Weezing, and Swalot, but (prior to Sword and Shield) isn't able to breed with other human-like Pokémon such as Alakazam or Machamp. Gardevoir being able to breed with Muk.Using Fly with a Pidgey, even though it's too small to carry the trainer.Alomomola not being a Luvdisc evolution, but Octillery evolving from Remoraid.BUT KYUREM HAS ARMS MADE OF ICE! Explanation Kyurem can't learn Ice Punch, despite having arms encased in ice, while Gastly and Wooper can learn Ice Punch despite having no arms at all.This spawned jokes about how Nidoking and Nidoqueen can't breed but Skitty and Wailord can, or making pedophilia jokes about how Nidoking can breed with a female Nidoran. Nidoqueen had menopause Explanation Curiously, while Nidoran females can breed, Nidorina and Nidoqueen can't.Explanation Grapploct, an octopus that lives in the ocean, is a pure Fighting type, while one of Urshifu's two forms is a Fighting/Water type for some reason. Ah yes, the elusive land octopus and the endangered undersea panda.This also applies to Pokémon such as the lake trio that are literally named after types of fairies in all languages, and Galarian Ponyta was in a similar boat before its Psychic/Fairy evolution was revealed. Like Charizard with dragons, Celebi is one of the most stereotypically fairylike Pokémon ever, but it remained Psychic/Grass-type when the Fairy type was introduced and it was retconned onto some older Pokémon, aside from the type containing some oddballs like Galarian Weezing, Kantonian Mr. Celebi isn't a fairy Explanation For some Pokémon species both new and old, the Fairy type is in a similar boat to the Dragon type.While it makes sense for it to keep its typing, it can't learn any Dragon moves besides Twister (which all the Forces of Nature can learn), despite having big claws and being a perfect candidate for Dragon Claw, making its situation even more egregious than Charizard and Gyarados in some ways. Thundurus' Therian Forme is based on the Azure Dragon, but retains the Electric/Flying type of its Incarnate Forme. Explanation The Therian Formes of the Forces of Nature are based on The Four Gods, which was made even clearer with the addition of Enamorus in Pokémon Legends: Arceus. The Vermillion Bird, the White Tiger, the Black Tortoise, and the Azure.Even when one of Charizard's Mega Evolutions is revealed to be part-Dragon, this meme still persists in some ways. Some fans have reconciled this oddity by distinguishing between 'dragon' and 'Dragon-type' as different concepts within Pokémon, which can be backed up both by official comments on Charizard and Gyarados ( not so much Lugia) and by how 'Dragon' elemental powers are treated in other franchises, as well as a quote from Lance in Pokémon Masters.

Charizard/Gyarados isn't a dragon Explanation Fans have long questioned the logic behind the Dragon typing, with Pokémon like Charizard, Gyarados, Lugia and Therian Forme Thundurus (which is based on the Azure Dragon of The Four Gods yet can't learn most Dragon-type moves), clearly based off traditional dragons, to not be Dragon-types, while actual Dragon-types include Altaria (a bird), Vibrava (an adult antlion), Goomy (a slug), Applin (a worm living inside an apple), Alolan Exeggutor (a 35-foot walking palm tree), Zygarde's alternate forms (an Animalistic Abomination Doberman and a Humanoid Abomination resembling a Humongous Mecha), and Eternamax Eternatus (a giant alien hand).
