Meganium Description

Meganium is the final evolution of Chikorita and Bayleef. It is a Grass-type Pokemon known for its flower-like design, calming aroma, strong defenses and access to useful support moves across the Pokemon series.

Competitive Overview

Is Meganium Good in Competitive?

Meganium is generally more defensive and supportive than many other starter Pokemon. It can use moves like Synthesis, Reflect, Light Screen, Leech Seed and strong Grass attacks to help teams survive longer and pressure Water, Ground and Rock-type Pokemon.

Meganium’s biggest strengths are its balanced bulk, support movepool and Mega Evolution in newer coverage. Its biggest issue is that pure Grass typing leaves it weak to Fire, Ice, Poison, Flying and Bug-type attacks.
