Iron Thorns
VGC Guide
Iron Thorns is one of the most explosive physical attackers in Trick Room teams: Quark Drive boosts 134 Attack by 30% to effective 174, and base 35 Speed acts first under Trick Room. Rock/Electric dual STAB combined with Rock Slide spread flinch creates nearly unstoppable momentum during Trick Room turns. 100 base HP and 110 base Defense provide solid survivability.
Quark Drive × Trick Room: Slow Speed Burst
Iron Thorns enters with Booster Energy to immediately activate Quark Drive, boosting 134 Attack to effective 174. Base 35 Speed combined with 0 Speed IVs and Brave nature reaches the minimum speed value, acting first under Trick Room against virtually every opponent. Electric Terrain can also activate Quark Drive, making Iron Thorns viable in Electric Terrain + Trick Room hybrid teams.
Rock Slide Spread: Flinch Mechanics & Rock/Electric Dual STAB
Rock Slide hits both opponents at 75 base power with 0.75 spread modifier, each with a 30% flinch chance. Under Trick Room Iron Thorns acts first, flinching opponents who then skip their entire turn — effectively doubling action denial pressure. Wild Charge provides Electric STAB single-target output; Earthquake covers Steel, Fire, and Rock types; Ice Punch handles Dragon, Grass, and Flying weaknesses.

How to Counter Iron Thorns
Iron Thorns’ Rock/Electric dual typing creates a critical Ground weakness from the Electric type. Garchomp’s Earthquake or Sandy Shocks’ Earth Power delivers massive damage, and can OHKO Iron Thorns outside of Trick Room. Ground coverage is the single most cost-effective counter to Iron Thorns.
Water moves deal ×2 damage to Rock-type Iron Thorns. Kyogre’s Origin Pulse spread can OHKO Iron Thorns outright. In non-Trick Room environments, fast Water-type Pokémon can deal decisive damage before Iron Thorns acts.
Iron Thorns’ primary advantage relies entirely on Trick Room being active. Taunting Trick Room setters, fast-KOing the setter before setup, or setting your own Trick Room to override the opponent’s all transform Iron Thorns’ 35 Speed from advantage into liability.
