Meganium
Grass
Best attacking moveset: Magical Leaf and Frenzy Plant, worth 10.9 damage per second against a neutral target.
Best moveset
Meganium can learn 12 combinations. Magical Leaf with Frenzy Plant does the most damage per second of them, at level 40 with a perfect attack stat. Same-type moves get the 1.2× bonus, and the cycle assumes the charged attack fires the moment it has the energy.
That set is legacy. Frenzy Plant is only obtainable with an Elite TM or from the event that gave it out, so the Meganium you catch today cannot learn it. The best set it can learn now is Magical Leaf and Solar Beam, worth 10.1 damage per second.
Stats and moves come straight from the game's own data files. Every number on this page is a raid and gym number, not a PvP one.
