Rapidash in depth
Gallop, no pun intended
Its Japanese name is ギャロップ, “Gallop”, the English word for the gait written in katakana and nothing more. It stands out in a generation where almost every name hides a double-meaning joke; there isn’t one here. The Western name does a little more work, although not much: rapid and dash, two words for the same idea, stacked on top of each other.
The design doesn’t hide it either. Cream-coloured horse, straight horn on its forehead, fire in its mane and tail. It’s a unicorn with the mythological part reduced to a minimum: the horn is there, but the creature behaves like a racehorse and its entries talk about kilometres per hour, not enchanted forests. The official category, Fire Horse Pokémon, follows the same literal approach.
What the split of Special did to it
In Generation I it had a single Special stat, 80, covering both Attack and Defense. When Generation II split that stat in two, it got an 80 and another 80: neither a gain nor a loss, which not every Pokémon can say. The rest of the sheet is unchanged from 1996, with the same 65 HP and the same 70 Defense.
What changed was everything around it. Abilities didn’t arrive until Generation III, and it was given Run Away or Flash Fire depending on the specimen; Flame Body appeared later as a hidden ability. The types introduced later didn’t hurt it either: it hits Steel super effectively and resists Fairy.
Galar’s white horse
Sword and Shield gave it a regional form that shares almost nothing with the original. White coat, pale blue eyes, long, curly mane and tail with cyan and pink streaks, and a longer violet horn. Its typing changes to Psychic and Fairy, with not a single flame in sight, and its abilities change completely: Pastel Veil, which protects the whole team from poisoning, or Anticipation as its hidden ability. Its moves include Psycho Cut. It shares its Pokédex number with the Kanto form and little else.
Against the other runners
Within its own type, it loses the comparison with Arcanine, which distributes more points, in more places and much earlier, because all it takes is a stone. As a fast pure-type sweeper, it has more in common with Zebstrika, Unova’s Electric equivalent: lots of Speed, respectable Attack and no defenses to back it up. The difference is recoil. Flare Blitz and Double-Edge, its two strongest hits, charge it a portion of the damage they deal, and on 65 HP that means turns of life disappearing on their own.
It has appeared in almost every main-series game since 1996, from Red and Blue to Pokémon Legends: Arceus, with the same two-stage line and no form that gives it the boost it lacks.
