Thwackey Weakness

Thwackey's Grass typing leaves it vulnerable to Fire, Ice, Poison, Flying, and Bug. 4 resistances help offset the weaknesses. 5 weaknesses means you'll want teammates that can handle the coverage gaps.

Thwackey Scarlet & Violet Guide

  • Thwackey is meant to evolve into Rillaboom. At 420 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

  • In Scarlet & Violet, watch for Arcanine (Fire), Walrein (Ice), and Roserade (Poison) when using Thwackey. They all hit it super-effectively with STAB. Flying and Bug-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Overgrow strengthens grass moves to inflict 1.5× damage at 1/3 max HP or less. That's the one you want on Thwackey. Grassy Surge is the hidden ability. Niche, but it has its uses.

  • Base 80 Speed is workable. Faster than some, slower than many. On offense, Thwackey is a physical attacker with base 85 Attack. Defensively? Enough bulk to take a hit or two.

  • For Scarlet & Violet, you can run Thwackey through the first few routes without issues. 420 BST won't carry you far though. Get it to Rillaboom as fast as you can.

Game Availability

Thwackey joined the series in Sword & Shield and has been available in 2 titles so far. With 3 generations of appearances, it's established itself despite the later start.
