In GSC, Earthquake was among the strongest moves, with 100 power, 10 PP and 100% accuracy. The only moves with comparable or higher power had other disadvantages:
- Hyper Beam, Sky Attack, Solar Beam and Skull Bash took two turns to execute.
- Hydro Pump, Mega Kick, Blizzard, Cross Chop and Fire Blast had 5 PP.
- Dynamic Punch, Thunder, Iron Tail and Megahorn had much lower accuracy.
- Double-Edge gave recoil damage and Dream Eater only worked on sleeping targets.
- Aeroblast and Sacred Fire were legendary signature moves.
Although Ground attacks are super-effective against five types (a record shared with Fighting), Earthquake and other Ground moves are terrible in PoGo, making Raikou and Heatran the only use cases for Ground attackers like Groudon and Garchomp.
What if Earthquake had its power in PoGo increased from 120 to 160? Would it be broken? To test this, I created a new move, Super Earthquake, in the DPS/TDO spreadsheet. I created “super” versions of Groudon, Garchomp and Rhyperior with the same fast moves but only one charged move (Super Earthquake). To show how better moves would benefit Ground-types in general, I also created a Super Bulldoze (with power 90 instead of 80) and a Super Mamoswine. (Both “super” moves had the same typing, EnergyDelta, duration and damage window as the originals.)
Firstly, here is how the Super versions compare to the originals in neutral DPS and neutral TDO.
They are not going anywhere near the top of the neutral DPS charts in extreme weather:
As for neutral TDO in extreme weather, Garchomp was already third and improves slightly, while Super Groudon becomes sixth (ignoring Arceus which is not released yet), comparable to Metagross but with 7.3% lower neutral DPS.
In clear weather, Super Groudon has the second-highest DPS (ignoring impractical Deoxys-A and unreleased Shaymin), trailing Blaziken by 3.2% but leading Moltres by 2.7%. Its TDO is 26.1% higher than Moltres, making Super Groudon the top clear weather generalist (but on gym offence, Moltres is resistant to Fairy moves).
Since there are no Poison-type legendaries, I will use Gengar as a basis for comparison. Super Groudon has 1.7% higher DPS and 1.8% higher TDO than Giratina-O, but 12% lower DPS than legacy Mewtwo.
Among the four Gen 5 legendaries weak to Ground attacks, Zekrom looks like the one which Groudon and Garchomp would shine most against. Is that true? Super Groudon only ranks 7th in DPS, 12.2% lower than Rayquaza, while Super Garchomp actually performs better with Dragon Tail, ranking 4th in DPS, 6.4% lower than Rayquaza. Since regular Garchomp already had the highest TDO against Zekrom, it is not surprising to see its lead increase and Super Groudon taking second place. Mamoswine would rank 8th in DPS (if both Garchomps are counted as one), but with its Ice set.
Their DPS against Reshiram is very similar, but Rampardos overtakes them in second place. The TDO here does not consider what moves Reshiram would have. Garchomp and Rhyperior resist Fire attacks, which Groudon is neutral to. Ignoring the duplicate Garchomp, Super Rhyperior would actually be 10th in DPS (20.7% lower than Rayquaza).
Against Cobalion, Super Groudon and Super Garchomp overtake Moltres and Machamp in DPS, but the gap is small (up to 3%). For comparison, Blaziken has 4.9% higher DPS than Super Groudon and 6.9% higher DPS than Super Garchomp. More importantly, normal Groudon ranks 4th in TDO (3.3% lower than Entei), but Super Groudon has 16.4% more TDO than Entei!
Terrakion has seven weaknesses and is thus a better gauge. Metagross is the ultimate counter. Ignoring impractical Deoxys-A and unreleased Shaymin, Super Groudon ranks 4th in DPS, 7.9% lower than Metagross, but with comparable TDO (only 0.5% lower).
The first four generations have four legendaries weak to Ground. Dialga has only one other weakness, to Fighting, but regular Groudon ranks only 8th in DPS (a massive 19% less than Breloom), but 1st in TDO. In contrast, Super Groudon ranks 1st in DPS (1% more than Breloom) and remains 1st in TDO, while Super Garchomp ranks 4th in DPS and 2nd in TDO. This is one matchup where Super Rhyperior (8th in DPS, 5th in TDO) and Super Mamoswine (9th in DPS) are worth using.
The next opponent to analyse is Regirock. Super Groudon has 6.9% lower DPS and 21.4% more TDO than current top counter Metagross.
DPS rankings for Registeel are similar to those for Cobalion, which shares the same weaknesses. However, we already know what moves Registeel has, so Moltres takes the TDO crown.
Last but not least, we just had an Entei raid day, where Super Earthquake would have shone. Super Groudon ranks second in DPS (10% lower than Rampardos) but has mediocre TDO due to not resisting Fire attacks, while Super Garchomp ranks third in DPS (11.8% lower than Rampardos) and third in TDO (17% lower than Palkia).
Ironically, Super Rhyperior performs better with Smack Down, reaching fifth in DPS (17.5% lower than Rampardos) and fourth in TDO (33.2% lower than Palkia). Even Super Mamoswine jumps to 7th in DPS, but its TDO is terrible as it is weak to Fire attacks.
- Rhyperior and Mamoswine simply do not have the stats to compete in DPS against other types.
- The proposed buff to Earthquake would give Groudon and Garchomp great but not broken DPS.
- By giving two bulky species a great one-bar move, the proposed buff to Earthquake may actually improve game balance.
