Overview

Meganium: another one of Game Freak's many defensive Grass-types. It is fairly balanced both offensively and defensively, but Meganium is probably one of the most underrated Pokemon in the tier. Its excellent bulk and great support movepool make it an ideal team supporter; 80 / 100 / 100 defenses and resistances to Water-, Ground-, and Electric-type attacks make it hard to KO Meganium, and it also has access to useful support moves such as Synthesis, Aromatherapy, Leech Seed, and dual screens. What makes Meganium truly unique, however, is its access to rare support moves that other Grass-types in the tier lack, such as Dragon Tail and Aromatherapy. Although it's competing in a tier it wasn't designed for, Meganium is a worthy opponent and a Pokemon you shouldn't overlook.

Support

Leftovers Relaxed / Bold
Moveset EVs
~ Synthesis
~ Giga Drain
~ Dragon Tail / Toxic
~ Aromatherapy
252 HP / 252 Def / 4 SpA

This set is the main reason to use Meganium in RU. With its good defenses and useful resistances, Meganium is an excellent team supporter. The idea is to switch into a Water-, Rock-, or Ground-type, wait for the opponent to switch out, then proceed with one of Meganium's support moves. Synthesis is Meganium's most reliable recovery move, while Giga Drain provides additional HP recovery and a decent STAB move. Dragon Tail is the main thing that sets Meganium apart from other Grass-types, but Toxic can be used to cripple bulkier Pokemon, such as Uxie. It's recommended that you set up multiple layers of entry hazards to make the most of Dragon Tail, but Stealth Rock should suffice. Finally, Aromatherapy keeps Meganium and its teammates free of status, and it's another defining advantage over the likes of Tangrowth and Ferroseed.

Dual Screens

~ Reflect
~ Light Screen
~ Aromatherapy / Leech Seed
~ Giga Drain
252 HP / 80 Def / 176 SpD

Although it lacks the utility of the previous set, dual screens Meganium has a certain level of surprise factor. Thanks to its ability to force the oppponent out with Dragon Tail, Meganium can set up dual screens with little trouble. Switch Meganium into a Choice-locked or weak attack, set up dual screens, then bring in a powerful sweeper to wreak havoc on the opposing team. Aromatherapy gives Meganium a way to keep itself and its teammates free of debilitating status, while Leech Seed can restore some of its health. Finally, Giga Drain deals respectable damage to the opponent and gives Meganium something to do should it be Taunted.

Other Options

Meganium has a rather average movepool, but this can be said for most Grass-types in the tier. Body Slam is an option alongside an Impish nature to spread paralysis, while GrassWhistle provides a less accurate means of crippling the opponent. Counter can be used to catch a physical attacker off-guard, but most opponents will be attacking Meganium from the special side. Meganium can use a Swords Dance set with Seed Bomb, Earthquake, and Return, but Meganium's average Speed and Attack make it an inferior Sceptile. A defensive Sunny Day set can support its teammates and give Meganium a charge-less SolarBeam—be sure to use teammates that benefit from the sun, such as Moltres, Victreebel, and Exeggutor. Rest and Sleep Talk provide an alternative form of recovery, but it's largely inferior to Synthesis and Aromatherapy. Finally, Leaf Storm hits hard off the bat and gives Meganium some firepower, but the Special Attack drop is off-putting.

Checks and Counters

Despite its excellent defensive potential and great support movepool, Meganium is brought to a halt by the majority of Grass-types in the tier. Lilligant, Tangrowth, and Ferroseed are immune to Leech Seed and take little damage from Giga Drain, while Roselia has STAB Sludge Bomb to deal heavy damage to Meganium. Fire-, Flying-, Poison, Ice-, and Bug-types deal heavy damage to Meganium, making Moltres, Drapion, and Scyther excellent counters. Sap Sipper Miltank and Bouffalant are immune to Grass-type moves and deal hefty damage with their STAB moves, while specially defensive Pokemon can set up on sets that lack a physical move. Taunt is arguably the best way to deal with Meganium as it relies on support and non-damaging moves and isn't exactly a hard-hitter. All in all, Meganium is an easy Pokemon to counter; the only thing you need to worry about is Dragon Tail and the prevalence of entry hazards.

Unreleased

Meganium's Dream World ability is Leaf Guard. It's largely pointless considering Meganium has access to Aromatherapy, but when the weather is sunny, Meganium cannot be afflicted with status.
