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.

The fragrance of a MEGANIUM’s flower soothes and calms emotions. In battle, it gives off more of its becalming scent to blunt the foe’s fighting spirit.

Meganium Weakness

Fragile

Type-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.

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.

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.

Can't catch Meganium directly. Start with Chikorita but it's a rare spawn from the locations below, then evolve at level 32. The 3-stage chain from Chikorita to Meganium is where the leveling time goes.

How to Obtain Meganium in Emerald

  • 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.

  • Meganium's biggest threats include Charizard (Fire), Cloyster (Ice), and Gengar (Poison), all carrying super-effective STAB moves. Flying and Bug-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

  • Bayleef evolves into Meganium at level 32. Meganium is the final evolution in a 3-stage line starting from Chikorita. At 525 BST, it's got solid stats to work with.

  • 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.

  • Meganium appears in 17 games, including Gold & Silver, Crystal, and Ruby & Sapphire.

Available in 17 titles since its debut in Gold & Silver, Meganium spans 8 generations of Pokemon games. It's accessible through wild encounters in most mainline games.
