[OVERVIEW]
Gastrodon is a standout defensive option for its excellent bulk, reliable recovery, and plentiful resistances to complement its sole Grass weakness. An Electric immunity means Gastrodon excels at grabbing momentum back from Volt Switch users like Kilowattrel and Toxtricity, enabling it to set up entry hazards. Similarly, Gastrodon has Storm Drain to check Inteleon and deny Flip Turn users like Basculegion, Vaporeon, and Milotic, though Sticky Hold is another great choice for a defensive ability by granting Gastrodon rare utility as an absorber of Knock Off and Trick. Such a robust defensive profile makes Gastrodon an excellent hazard setter, and it boasts access to both Stealth Rock and Spikes. That said, Gastrodon's 4x Grass weakness is a major Achilles heel, leaving it wide open to being taken advantage of by Grass-types like Amoonguss, Decidueye, and Tsareena. Gastrodon's lower Defense is another shortcoming, leaving physical attackers like Toxicroak, Paldean Tauros-W, and Flygon capable of breaking through it. Not only does Gastrodon hardly deter Bronzong from taking advantage of it, but its passivity means other Calm Mind sweepers like Scream Tail and Uxie can use it as setup fodder.

Set Details
====
Ice Beam prevents Ground-immune Pokemon from taking advantage of Gastrodon and particularly threatens Ice-weak Pokemon like Flygon, Kilowattrel, and Grass-types. Sludge Bomb is another anti-Grass-type coverage move with perks such as letting Gastrodon fish for poison and doing more damage to Sylveon, Scream Tail, and Tera Fairy users like Bronzong and Incineroar. Surf hits Bronzong and Rotom-H, and its decent power with STAB still prevents Ground-immune Pokemon from totally exploiting Gastrodon. However, it weakens Gastrodon's matchups against Grass-types and freely invites them in. Heavy-Duty Boots protects Gastrodon from being worn down by entry hazards. The Water immunity granted by Storm Drain makes Gastrodon an even more effective answer to Inteleon, helps it take advantage of Choice item Paldean Tauros-W and Basculegion, and slows the momentum otherwise gained by Flip Turn users like Swampert, Milotic, and Vaporeon. Sticky Hold is an alternative to deny item disruption from Knock Off users like Incineroar, Gligar, and Alolan Muk. Covert Cloak is best run on Sticky Hold sets so that Gastrodon can effectively counter Alolan Muk. Sticky Hold Gastrodon can run an EV spread of 252 HP / 180 Def / 76 SpD to make Alolan Muk's Knock Off a 4HKO instead of a 3HKO or 2HKO. Tera Ghost lets Gastrodon act as effective spinblocker for itself and more comfortably answer Toxicroak, Toxtricity's Boomburst, and Cinccino. Tera Fairy makes Gastrodon a decent answer to Fighting-types like Flamigo and an especially good check to Paldean Tauros-W, though this worsens Gastrodon's matchup against Toxicroak. Tera Poison flips Gastrodon's 4x Grass weakness, grants it an immunity to poison, and enables it to answer Fighting- and Poison-types like Toxicroak and Amoonguss.
Bronzong is a superb partner to Gastrodon, handling Grass-types and enabling Gastrodon to run Spikes if it runs Stealth Rock. Gastrodon matches Bronzong by intercepting Fire-types like Hisuian Typhlosion, absorbing Knock Off if it has Sticky Hold, and checking special attackers like Kilowattrel and Toxtricity that could wear down Bronzong. Orthworm is similar to Bronzong, but it can check physical attackers like Flygon and Cinccino for Gastrodon. Alolan Muk and Incineroar can both check Grass-types for Gastrodon, and they both have Knock Off to remove Heavy-Duty Boots and maximize the reach of Gastrodon's entry hazards. Pokemon like Chandelure and Diancie value Storm Drain Gastrodon's ability to answer Water-types; Chandelure can return the favor by checking Grass-types, while Diancie's access to Stealth Rock lets Gastrodon create a hazard stacking hazard-stacking core with it. Avalugg's physical bulk pairs nicely with Gastrodon's role as a special wall. Other checks to Grass-types like Registeel, Galarian Slowbro, and Overqwil also stand out for covering Gastrodon's most significant weakness. Wallbreakers like Flamigo, Choice Band Flygon, and Porygon-Z thrive from the passive damage Gastrodon spreads with its entry hazards. Scyther is a significant partner thanks to its potential to check Grass-types and capitalize on Gastrodon's entry hazards, while Gastrodon checks Fire-, Steel-, and Water-types in return. Gastrodon's Sticky Hold making it an effective Knock Off absorber is appreciated by Pokemon that depend on their items, including Avalugg, Gligar, and Bronzong.
[STRATEGY COMMENTS]
Other Options
====
A physically defensive EV spread can be used to make Gastrodon a better wall against physical attackers, including Incineroar, Toxicroak, Overqwil, and Paldean Tauros-W. Earthquake is more threatening to specially bulkier Pokemon like Alolan Muk, Munkidori, and Tentacruel. Tera Dragon helps Gastrodon check Grass-types like Decidueye, Electric-types like Kilowattrel, Fire-types like Chandelure, and Water-types like Inteleon and Basculegion all at once. Additionally, it improves Sticky Hold Gastrodon's matchup against Water-types that it would otherwise struggle against without Storm Drain.
Checks and Counters
====
**Grass-type Pokemon and Coverage**: Breloom, Brambleghast, and Amoonguss can come in on Gastrodon and exploit its 4x Grass weakness to beat it or scare it out. However, they should be wary of switching into its coverage moves. Chandelure threatens Gastrodon with Energy Ball, though it does not switch into Earth Power or Surf comfortably. Scyther can use Trailblaze to both set up on Gastrodon and potentially OHKO it.
**Physical Wallbreakers**: Lower Defense means Gastrodon poorly answers foes like Toxicroak, Heracross, and Choice Band Flygon. If it lacks Storm Drain, Water-types like Basculegion and Paldean Tauros-W can much more effectively run through Gastrodon.
**Status**: Gastrodon is much less effective as a defensive Pokemon when afflicted by status, often forcing it to become more passive by using Recover more often. Munkidori's Toxic Chain can passively inflict Gastrodon with this status just by using U-turn, Goodra has the bulk to stomach Ice Beam from Gastrodon and status it, and Bellibolt and Gligar can use Toxic on Gastrodon as it switches in.
