While most trainers evolve Thwackey into Rillaboom immediately, the unevolved form has a niche with Eviolite boosting its defenses. 5 type weaknesses to keep in mind. Introduced in Gen 8. Needs some investment to avoid getting outsped.
Attack and Speed carry most of Thwackey's stat budget. Sp. Atk's the obvious dump stat. Tough to catch and yields 2 Attack EVs. Follows a 1.06M XP medium-slow curve.
The faster a Thwackey can beat out a rhythm with its two sticks, the more respect it wins from its peers.
When it’s drumming out rapid beats in battle, it gets so caught up in the rhythm that it won’t even notice that it’s already knocked out its opponent.
Thwackey Weakness
FragileThwackey's Grass typing leaves it vulnerable to Fire, Ice, Poison, Flying, and Bug moves. 4 resistances help offset the weaknesses. 5 weaknesses means you'll want teammates that can handle the coverage gaps.

How to Obtain Thwackey in Sword & Shield
Step 1Obtain Grookey
Step 2Thwackey ✓
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.
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.
Thwackey can be found in Scarlet & Violet and Sword & Shield.
Thwackey joined the series in Sword & Shield and has been available in 2 titles so far. With 2 generations of appearances, it's established itself despite the later start.
