Garchomp in depth
A shark with landing gear
The design mixes things that should not fit together. Underneath is a land shark, that fictional creature that swims beneath the sand, with dorsal fins, a pointed snout and the two lateral head extensions taken from the hammerhead shark. On top is a fighter jet: the wing profile, the posture in flight and the toothy mouth at the front call to mind the P-40 Warhawks that had shark jaws painted on their noses and were known as desert sharks. Beneath all of that is the wyvern, the bipedal dragon of European heraldry, which explains why the wings are also its arms.
The Japanese ガブリアス (Gaburias) combines がぶり (gaburi, the sound of a large bite) with carcharias, the second half of the scientific name for the great white shark. The English Garchomp keeps the first syllable and adds chomp, which means the same thing in another language: to bite hard.
What changed over twenty years
It debuted in Generation IV with Sand Veil as its only ability, at a time when sandstorms were common and that extra evasion drove everyone crazy. Generation V gave it Rough Skin as its hidden ability and completely changed how you play against it: it is no longer a matter of luck, but a fixed toll the opponent pays for every contact hit.
Generation VI was the bad one. The Fairy type arrived to rein in dragons and added a weakness it had never had before, in the same package that brought Mega Evolution. Mega Garchomp trades Speed for brute force, with its arms turned into blades and Sand Force as its ability, and the result is debatable: it loses exactly what made the original work. It has three forms in total: the regular one, Mega Garchomp and a Mega Garchomp Z variant.
The level 48 one
Evolving that late has consequences in a normal playthrough. Gabite hangs around for twenty-four levels before making the jump, and until then the whole package performs below what those final 600 points suggest. When it arrives, it arrives fully formed: Dig at 52, Sandstorm at 62 and Dragon Rush at 82, although by then almost nobody is waiting for level-up moves.
In Sinnoh, the first one you encounter is on the other side. Champion Cynthia carries it as the centrepiece of her team in Diamond, Pearl and Platinum, and that battle is one people remember for how badly it goes the first time. In Scarlet and Violet, the Haban Berry it can be holding reduces the damage from a super-effective Fairy-type hit — a small patch for the hole the Fairy type opened in it three generations ago.
