In-Depth Analysis
With a base stat total of 475, Gastrodon plays as a balanced Pokémon with a flexible stat spread. Its standout stat is HP at 111, while Speed (39) is the clear soft spot — build sets that protect that weakness.
Defensively, the Water, Ground combination gives Gastrodon 4 resistances, 1 immunity, and 1 weakness to plan around. Watch out for Grass moves in particular — they land for 4× damage. Offensively it pressures 6 types with super-effective STAB coverage.
A catch rate of 75 puts Gastrodon in the moderate range — a few Great Balls usually get the job done. It levels on the Medium experience curve. Defeating it grants HP +2 EVs, which is worth remembering when EV-training your own team.
