With Athenian, Mega Stunfisk gains an effective 182 special attack, easily the highest attacking stat in it tier. It’s no slouch defensively either, with 109/104/134 defenses backing up Athenian’s power. It’s good STAB combination allows it to check and counter a number of potent threats such as Skarmory, Talonflame, and Mega Manectric, and is very difficult to switch into if predicted wrong.
Unfortunately, that same Electric/Ground STAB combo that makes it potent also leaves it weak to common attacks from Ice, Water and Grass types. Not helping matters is its very slow 57 base speed and a lack of priority moves. Finally, outside of the unreliable Rest, it has no form of recovery and is prone to being worn down by status or otherwise.
Even with these issues, Mega Stunfisk is still a potent counter and devastating wallbreaker that can handle a number of threats, even if it does have to make do with a lacking speed.
Final Verdict: OU, with Ubers potential
Set 1: Wallbreaker
Nature: Modest EV: 146 HP/252 SpA/112 Spe Item: Stunfiskite
- Earth Power
- Sludge Bomb/Stealth Rock/Livewire
Thunderbolt is M-Stunfisk’s main attack, hitting much of the tier for massive damage thanks to Athenian. Earth Power rounds out Stunfisk’s STAB combo, hitting much of what Thunderbolt can’t. Scald is the third option, allowing M-Stunfisk to hit Pokemon such as Landorus and Gliscor, who would otherwise wall this set completely, in addition to creating a burn chance. The fourth move is the surprise. Sludge Bomb can be used to punish Grass and Fairy types, with the bonus of poisoning them. If Grass coverage is not needed, then entry hazards such as Stealth Rock or Livewire can be considered, depending on your team makeup.
A specially defensive set, with EVs spread primarily into HP and Special Defense and running the RestTalk set with TBolt and Earth Power, can allow Stunfisk to work as a wall, while still having Athenian’s raw power. However, this set struggles with checks and is otherwise outclassed by the Wallbreaker set.
Checks and Counters
Grass Types: If M-Stunfisk isn’t carrying Sludge Bomb/Wave, then it becomes very vulnerable to Pokemon such as Serperior, Amoongus, and Mega Venusaur. Even then, however, a number of them apart from Serperior and Breloom can take at least one Sludge Bomb and proceed to threaten it out. Serperior, however, struggles to switch in and requires a safe switch to be effective. Chesnaught stands out as a check due to its immunity to Sludge Bomb, but fears Sludge Wave.
Water-types: While they’re taken out handily by Thunderbolt, water Pokemon such as Volcanion, Gyarados-M and Rotom-W can take advantage of M-Stunfisk’s low speed and proceed to 2HKO or even OHKO it with their attacks. Rotom has a particularly easy time, taking only neutral damage from Thunderbolt and proceeding to threaten it with Hydro Pump. Volcanion, however, requires a slow Baton Pass or another Pokemon fainting to be able to handle M-Stunfisk.
Ice Types: Pokemon such as Weavile and Kyurem-B will prove to give M-Stunfisk a hard time, as they can threaten to decimate it with their STAB ice attacks. Weavile, however, cannot switch in safely against any of M-Stunfisk’s attacks.
Ground types: Pokemon such as Excadrill, Landorus-T, and Garchomp can outspeed M-Stunfisk and threaten it with an Earthquake, oftentimes forcing it out. Landorus-T is particularly good at this, as it is immune to both of M-Stunfisk’s STAB’s. However, all of them fear Scald.
Faster Attackers: As M-Stunfisk is very slow, many attackers, such as M-Heracross, Delta Gallade/Gardevoir, and Diggersby can come in and force pressure on its weaker defense stat, often leaving it in an undesirable position.
Special Walls: Chansey is a surefire counter to M-Stunfisk, being able to soak up a number of hits that it dishes out, and can proceed to cripple it badly. Other walls such as Goodra, Latias and Latios can also survive at least one hit.
Status: While M-Stunfisk is immune to paralysis, it absolutely loathes Toxic and burns, as it puts the mon on a timer and puts even more pressure on it. This is not helped by its complete lack of recovery options.
