Meganium doesn't stand out in any single area, but it gets the job done for in-game teams. 5 type weaknesses to keep in mind. Been around since Gen 2. Known as the Herb Pokemon. Flexible enough to run physical or special sets.
An unusually even spread gives Meganium flexibility. Defense barely edges ahead. But HP isn't far off. Tough to catch and follows a 1.06M XP medium-slow curve. Yields 3 Defense and Sp. Def EVs.
MEGANIUM’s breath has the power to revive dead grass and plants. It can make them healthy again.
The aroma that rises from its petals contains a substance that calms aggressive feelings.
Meganium Weakness
FragileType-wise, Meganium takes extra damage from Fire, Ice, Poison, Flying, and Bug. 4 resistances help offset the weaknesses. Meganium's overall bulk (80/100/100) lets it take a hit or two from most weaknesses before going down.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
End of the line. Meganium caps a three-stage chain that started at Chikorita. Breeding produces the base form, and eggs are average hatch time. HP grew the most through evolution (+35 over Chikorita), and Meganium peaks at 525 total stats.
How to Evolve
Breed with Meganium to get Chikorita eggs easily using 35 partners from the Plant and Monster egg groups. Notable egg moves include Ancient Power, Counter, Flail and 5 more.
The special wall spread is where Meganium earns its spot. Leftovers for passive recovery each turn, Calm nature for the right lean, and Synthesis handles sustain. Overgrow does the rest without needing a move slot.

The egg pool carries weight here. Ancient Power and Counter aren't available any other way for Meganium, and they meaningfully change what it threatens. Stack those on top of Solar Beam and Giga Drain for solid options.

Meganium can't be caught in FireRed & LeafGreen. Transfer Chikorita from Gold, Crystal, or Brilliant Diamond and evolve through the 3-stage chain to get it. The step cards below map the full chain.
How to Obtain Meganium in FireRed & LeafGreen
We rate Meganium C-Tier — a situational pick that fills a niche. At 525 BST, it fits the support role. Base 100 Defense stands out.
Overgrow is the go-to ability for Meganium. It strengthens grass moves to inflict 1.5× damage at 1/3 max HP or less. Its hidden ability Leaf Guard can work in specific setups.
Base 80 Speed is workable — faster than some, slower than many. On offense, Meganium is a physical attacker with base 82 Attack. Defensively? Tanky enough to absorb a few hits. Best used as a support.
