However, raw damage is not the only thing that matters. A strong Grass-type Mega should also survive long enough to support the rest of the raid team. Typing, bulk, moveset quality, and secondary uses can all change how valuable a Pokémon feels in real battles.
This ranking compares every known Grass-related Mega Evolution based mainly on its performance as a Grass-type PvE attacker. Overall usefulness, passive bonuses, PvP potential, and secondary typing are also considered when assigning each tier.
Some Mega Evolutions listed below have not yet been released in Pokémon GO. Their placements are based on currently available stats and moves, so their final performance may change before release.
Grass-Type Mega Evolution Ranking
| Rank | Mega Evolution | Tier | Best Grass Moveset |
|---|---|---|---|
| 1 | Mega Chesnaught | A | Vine Whip + Frenzy Plant |
| 2 | Mega Sceptile | A | Bullet Seed + Frenzy Plant |
| 3 | Mega Meganium | A | Vine Whip + Frenzy Plant |
| 4 | Mega Venusaur | A | Vine Whip + Frenzy Plant |
| 5 | Mega Victreebel | B | Magical Leaf + Leaf Blade |
| 6 | Mega Scovillain | D | Leafage + Grass Knot |
| 7 | Primal Groudon | S | Mud Shot + Solar Beam |
| 8 | Mega Abomasnow | B | Razor Leaf + Energy Ball |
The ranking and tier score measure two different things. Mega Chesnaught ranks first specifically as a Grass attacker, while Primal Groudon receives an S-tier overall score because of its wider value across raids, PvP, and passive bonuses.
8. Mega Abomasnow
Best moveset: Razor Leaf + Energy Ball
Mega Abomasnow is useful, but not because of its Grass-type damage. Its combination of Razor Leaf and Energy Ball falls behind stronger Grass attackers, including several non-Mega options.
Its Grass/Ice typing also creates problems. Ice adds weaknesses to Fighting, Rock, Steel, Bug, Poison, and Flying, while making it double weak to Fire. This hurts its survival in several matchups where a Grass attacker would normally feel comfortable.
Its stats are also fairly balanced rather than heavily focused on damage. With 240 Attack, 191 Defense, and 207 HP, it lacks the offensive pressure needed to compete with the top Grass Megas.
The reason it still earns a B-tier overall score is its Ice-type performance. Mega Abomasnow remains much more valuable when used with an Ice moveset, especially against Dragon- and Ground-type targets. Its unique Grass/Ice typing also gives it a useful combination of Mega bonuses.
As a Grass attacker, though, it is clearly the weakest option on this list.
7. Primal Groudon
Best Grass-focused moveset: Mud Shot + Solar Beam
Primal Groudon is not actually a Grass-type Pokémon. However, its Primal bonuses also support Grass types, so it fills a similar role to a Grass Mega Evolution.
It has incredible base stats, including 353 Attack, which allows it to use Solar Beam far more effectively than most non-Grass attackers. Mud Shot also generates energy quickly, helping it reach the expensive Charged Move sooner.
There are still two major drawbacks. Groudon has no Grass-type Fast Move, and Solar Beam does not receive a same-type attack bonus. Those limits prevent it from matching the best true Grass attackers.
Even so, its stats are so high that it can still perform reasonably well in the role. More importantly, this is only a bonus function. It remains one of the strongest Ground- and Fire-related choices in the game, while also boosting three different types through its Primal effect.
For pure Grass damage, it ranks near the bottom. For overall account investment, it is easily one of the strongest options in the entire article.
6. Mega Scovillain
Best projected moveset: Leafage + Grass Knot
Mega Scovillain has not been released in Pokémon GO, and even its base form is currently unavailable. Its placement is therefore based on its projected stats and datamined moves.
On paper, 276 Attack gives it respectable offensive potential. Unfortunately, its Grass/Fire typing works against it in most situations where players need a Grass attacker.
Grass Pokémon are normally used against Water-, Ground-, and Rock-type enemies. Fire is weak to all three. As a result, the dual typing removes Scovillain’s resistance to Water and Ground while making it weak to Rock.
That means it can take heavy damage in the exact battles where it is supposed to perform best. Its relatively low 170 Defense and 163 HP make this issue even worse.
A better final moveset could improve its damage, but it would not fix the defensive problem. Primal Groudon also provides similar passive bonuses while offering much stronger overall performance.
Mega Scovillain may still have a niche as a Fire attacker with Grass-related bonuses, but it is unlikely to become a top Grass Mega.
5. Mega Victreebel
Best moveset: Magical Leaf + Leaf Blade
Mega Victreebel is a solid Grass attacker with good damage, acceptable bulk, and a reliable moveset. Magical Leaf paired with Leaf Blade allows it to apply steady pressure without relying on a slow, expensive Charged Move.
Its 265 Attack is strong enough for raid content, while 181 Defense and 190 HP prevent it from feeling too fragile. The Grass/Poison typing does make Ground attacks hit for neutral damage, but this is not a major weakness in most battles.
The real problem is competition.
Mega Venusaur shares the same Grass/Poison typing and has access to Frenzy Plant, one of the strongest Grass-type Charged Moves in Pokémon GO. Victreebel can compete when Venusaur does not have its exclusive move, but it struggles to keep up once Frenzy Plant enters the comparison.
Magical Leaf may also require an Elite Fast TM or a special event. Without it, Victreebel must use Razor Leaf, which lowers its performance.
This is still a good Mega Evolution. It simply lives in the shadow of a very similar and usually stronger alternative.
4. Mega Venusaur
Best moveset: Vine Whip + Frenzy Plant
Mega Venusaur remains one of the safest Grass-type Mega Evolutions to build. It combines a strong moveset with excellent bulk and a useful secondary Poison typing.
Its 241 Attack is lower than several other contenders, but 246 Defense helps it stay on the field longer. That extra survival time lets it use more Frenzy Plants and maintain its Mega damage bonus for teammates.
The Grass/Poison typing is not perfect. Poison removes Grass’s resistance to Ground-type damage, which slightly hurts Venusaur in one of its main raid matchups. This small weakness is one reason it ranks below the top three.
Still, the difference is not large. Vine Whip charges energy quickly, while Frenzy Plant provides the damage needed to remain relevant despite years of power creep.
Mega Venusaur also has value outside pure Grass damage. Its typing can provide useful Candy bonuses, and Poison coverage gives it a small niche in selected matchups.
For players who already have a strong Frenzy Plant Venusaur, this is still one of the most dependable Grass Mega investments.
3. Mega Meganium
Best projected moveset: Vine Whip + Frenzy Plant
Mega Meganium is another unreleased option, but its projected Pokémon GO stats look surprisingly strong.
Regular Meganium has always been known for bulk rather than damage. Its Mega Evolution changes that balance by raising its projected Attack to 276 while keeping a solid 232 Defense and 190 HP.
The new Grass/Fairy typing is also useful. It adds weaknesses to Steel and a double weakness to Poison, but those attacks are not common in most Water-, Rock-, or Ground-type raid matchups. Against the targets a Grass attacker normally faces, Meganium keeps its important resistances.
Frenzy Plant once again plays a major role. With Vine Whip generating energy and its stronger offensive stats supporting the Charged Move, Mega Meganium should become an effective mix of damage and durability.
Its Fairy typing may eventually create extra value if it receives a strong Fairy moveset. At present, that part of its kit remains uncertain.
Based on the currently available information, Mega Meganium looks like a strong all-round Grass attacker with fewer defensive risks than Mega Venusaur.
2. Mega Sceptile
Best moveset: Bullet Seed + Frenzy Plant
Mega Sceptile is the most aggressive Grass attacker in the ranking. Its 320 Attack gives it the highest damage potential among the Grass Megas discussed here.
That power comes at a cost. With 186 Defense and 172 HP, it is less durable than Mega Venusaur, Mega Meganium, or Mega Chesnaught. It plays more like a glass cannon and may leave the field sooner against hard-hitting Raid Bosses.
Its Grass/Dragon typing is what pushes it near the top.
The Dragon typing gives Sceptile a double resistance to Water, making it especially effective against Water-type enemies. Even with lower defensive stats, it can survive repeated Water attacks while dealing excellent damage with Frenzy Plant.
Players must watch for Ice coverage. Grass/Dragon is double weak to Ice, so one unexpected Ice-type Charged Move can remove it quickly.
As a Dragon attacker, Mega Sceptile is much less impressive because it lacks a complete high-level Dragon moveset. Its value is heavily focused on Grass-type damage.
For Water-type raids, however, few options can match its combination of DPS and resistance.
1. Mega Chesnaught
Best projected moveset: Vine Whip + Frenzy Plant
Mega Chesnaught takes first place because it offers the best balance of moves, bulk, and matchup resistance.
Its projected 242 Attack is not as high as Sceptile’s, but its 282 Defense and 204 HP make it far harder to remove. This allows it to stay active longer, use more Frenzy Plants, and keep boosting other players’ Grass-type attacks.
The Grass/Fighting typing is the key advantage.
Grass naturally resists Water and Ground, while Fighting adds a resistance to Rock. That makes Mega Chesnaught the only option in this ranking that resists all three of the main types Grass attackers are commonly used against.
It does have several weaknesses, including a double weakness to Flying. However, many of those weaknesses are less relevant in standard Grass-favored raid matchups.
Vine Whip and Frenzy Plant also give it one of the best possible Grass-type movesets. Unless its moves change before release, it should become an extremely consistent raid attacker.
Mega Sceptile may deal damage faster, but Mega Chesnaught’s stronger survival and better overall matchup profile give it the top position.
Which Grass-Type Mega Evolution Should You Build?
For most players, the best choice depends on the content they are preparing for.
Mega Chesnaught is expected to be the best general Grass attacker once it becomes available. It has the ideal combination of bulk, resistances, and Frenzy Plant access.
Mega Sceptile is the best current choice for fast damage, especially against Water-type Raid Bosses. Its double Water resistance can make up for its lower bulk.
Mega Venusaur is the safest established investment. It has been available for a long time, performs consistently, and does not depend on an unreleased Mega Evolution.
Primal Groudon is the best overall account investment, even though it is not the best dedicated Grass attacker. It provides far more value across different battle types and passive bonuses.
Mega Meganium also has strong potential, but its final value will depend on its release moveset.
Frequently Asked Questions
What is the strongest Grass-type Mega Evolution in Pokémon GO?
Mega Chesnaught is projected to be the strongest overall Grass-type Mega because it resists Water, Ground, and Rock attacks while using Vine Whip and Frenzy Plant. However, it has not yet been released, so its final performance may change.
Is Mega Sceptile better than Mega Venusaur?
Mega Sceptile usually deals more damage and performs especially well against Water types because of its double resistance. Mega Venusaur is bulkier and can be easier to use in matchups where Sceptile risks taking Ice-type damage.
Is Primal Groudon a Grass-type Mega Evolution?
No. Primal Groudon is a Ground/Fire Pokémon. It is included because its Primal bonuses also affect Grass types, allowing it to function like a Grass Mega for Candy bonuses and team support.
Does every Grass Mega need Frenzy Plant?
No, but Frenzy Plant gives the Grass-type starters a major advantage. Mega Victreebel remains usable with Leaf Blade, while Mega Abomasnow and Mega Scovillain use other Grass moves. Still, the strongest dedicated Grass attackers usually benefit from Frenzy Plant.
