Thwackey Description

Thwackey evolves from Grookey and later evolves into Rillaboom. It is a Grass-type Pokemon introduced in Generation 8 and is known for its rhythm-based design and two-stick drumming style.

Competitive Overview

Is Thwackey Good in Competitive?

Thwackey can be useful in some formats because it has stronger stats than Grookey while still retaining access to helpful Grass-type moves, utility options and Grassy Surge as a Hidden Ability. It can pressure teams with pivoting, item disruption and terrain-based support.

Thwackey’s biggest strengths are its utility movepool, Grass typing and ability to support teammates through terrain. Its biggest issue is that Rillaboom usually offers much stronger offensive pressure and better overall stats in standard competitive formats.
