They hate each other. Honestly, that’s the simplest way to describe the relationship between the two most influential legendaries in the history of the franchise. If you’ve spent any time playing the Ruby, Sapphire, or Emerald versions—or if you’re currently grinding the Master League in Pokémon GO—you know that pokemon groudon and kyogre aren't just mascots. They are foundational pillars of how the game actually functions.
Think back to 2002. Game Freak was transitioning to the Game Boy Advance. They needed something bigger than birds or dogs. They gave us the personification of the earth and the sea. It changed everything.
The Weather Wars: More Than Just Flavor Text
When people talk about pokemon groudon and kyogre, they usually start with the lore. The Hoenn region was basically a giant "what if" scenario regarding climate change. Groudon wants to expand the landmass to give people and Pokémon more room to live. Kyogre wants to raise the sea levels because, well, that’s where life started. They are locked in a perpetual stalemate that only Rayquaza can break.
But the lore isn't why they're important. The mechanics are.
Before Generation 3, weather was a move you had to manually use. It took a turn. It was slow. Then came Drizzle and Drought. The moment Kyogre hits the field, it starts raining. The moment Groudon steps up, the sun comes out. This sounds simple, but it shifted the entire competitive landscape into what we now call "Weather Wars."
If you’re running a Kyogre, your Water-type moves get a 50% boost immediately. Your Thunder never misses. If your opponent switches in Groudon, that rain vanishes. Now your Water moves are weakened, and Groudon’s Fire-type coverage (like Fire Punch or Heat Crash) is suddenly terrifying. It’s a constant tug-of-war. This isn't just "flavor." It is the core of high-level VGC (Video Game Championships) play.

Kyogre: The King of Consistent Violence
Kyogre is often cited as the most "efficient" legendary ever made. Its base Special Attack is staggering. Usually, you’ll see players slap a Choice Scarf on it. Why? Because a Choice Scarf Kyogre using Water Spout at full HP is one of the most oppressive forces in the game. It hits both opponents in doubles. It deletes anything that doesn't resist it.
Even after years of power creep, Kyogre remains the gold standard.
Look at the 2016 and 2019 "Primal" metas. Primal Kyogre gained Primordial Sea, an upgraded version of rain that completely nullifies Fire-type moves. It made Groudon’s primary STAB (Same Type Attack Bonus) moves useless unless Groudon was faster and could override the weather.
Why Kyogre stays on top:
- Type Advantage: Water is arguably the best offensive type in the game.
- Move Pool: Access to Origin Pulse, Ice Beam, and Thunder provides near-perfect coverage.
- Simplicity: You don't need a complex strategy. You click Water Spout. You win.
Groudon: The Versatile Juggernaut
Groudon is different. While Kyogre is a sledgehammer, Groudon is a Swiss Army knife that happens to be the size of a mountain. It has better physical bulk and a more varied move pool.
For a long time, Groudon was actually considered the "weaker" of the two because its Ground typing didn't benefit from the Sun as much as Water benefited from Rain. Then came Generation 6 and Primal Reversion. Primal Groudon became a Ground/Fire type.
This was a massive buff. Its new ability, Desolate Land, creates "Harsh Sunshine" which evaporates all Water-type moves. Suddenly, Groudon’s biggest weakness—a 4x weakness to Water—was gone as long as it stayed on the field. It became the most used Pokémon in the history of the VGC 2016 format. Literally almost every winning team had one.
The Pokémon GO Factor
If you aren't a competitive console player, you probably know pokemon groudon and kyogre from Raids. In Pokémon GO, they are Tier 5 essentials.
Kyogre with Origin Pulse is the best non-Mega Water attacker. Period. Groudon with Precipice Blades is the gold standard for Ground attackers. If you are trying to take down a Heatran, a Nihilego, or any Electric-type raid boss, you need Groudon.
The introduction of Primal Reversion in Pokémon GO followed the main series' logic. These aren't just temporary buffs; they provide massive "Primal Bonuses" to your entire raid group. Kyogre boosts Water, Electric, and Bug types. Groudon boosts Fire, Grass, and Ground.
What most people get wrong about the Primal forms
A lot of casual players think you should just use them whenever you have the energy. That's a waste. Because Primal Reversion lasts for 8 hours, you should timing it for specific "Raid Hours" or Community Days.
Also, don't ignore their movesets. If your Groudon doesn't have Precipice Blades, it’s significantly worse. We’re talking a roughly 20% drop in DPS (Damage Per Second) compared to Earthquake. You need an Elite Charged TM for this, but it is one of the few instances where using one is actually worth it.

The Design Philosophy: Why They Work
Most legendaries feel "designed." You can see the artist's hand in things like Palkia or Dialga—they look like aliens or deities. Groudon and Kyogre look like forces of nature.
Ken Sugimori, the lead designer, nailed the "ancient" aesthetic. Groudon’s skin looks like tectonic plates shifting. Kyogre’s fins look like a mix of an orca and a stealth bomber. They feel heavy. When they enter the arena, the music changes. The screen shakes.
This "weight" is missing from a lot of newer legendaries. In Pokémon Scarlet and Violet, the "Treasures of Ruin" are cool, sure. But they don't feel like they could actually reshape a continent. Groudon and Kyogre do.
Competitive Nuance: The Speed Creep
In the current meta, speed is everything. Groudon and Kyogre both share a base speed of 90. This is a very specific, very intentional number.
It creates a "Speed Tie."
If both lead the match, the slower Pokémon's weather will actually stay on the field. This creates a weird paradox where you sometimes want your legendary to be slower than your opponent's. It’s these kinds of mind games that keep players coming back to these two after 20 years.
You aren't just playing a game of elemental rock-paper-scissors. You're managing atmospheric conditions.
Essential Kit for Groudon
If you're building one for a competitive team today, you have to decide: offensive or defensive?
- The Offensive Build: Focus on Attack and Speed. Use a Life Orb or Choice Band. Spam Precipice Blades.
- The Utility Build: Use it to set up Stealth Rocks. Give it a Sitrus Berry. Use Thunder Wave to disrupt.
Essential Kit for Kyogre
Kyogre is less flexible, but that's because it's already perfect at what it does.
- The Scarf Set: Max Speed, Max Special Attack. Water Spout. Clean up late game.
- The Calm Mind Set: Give it some bulk. Use Calm Mind once or twice. Now it’s unkillable and hits like a truck.
What Really Happened in Emerald?
There’s a common misconception that Groudon and Kyogre were "evil" in the games. They weren't. Team Magma and Team Aqua were the ones acting out. The Pokémon themselves were basically just woken up from a nap and were extremely cranky.
In Pokémon Emerald, the scene where Rayquaza descends from the sky to scream them into submission is still widely considered the peak of Pokémon storytelling. It showed that even these titans have a hierarchy. It grounded the world. It made the stakes feel real.

Final Practical Insights for Trainers
If you're looking to optimize your roster, here is what you actually need to do with pokemon groudon and kyogre:
- Check the IVs for Speed: In the main series, a "No Good" Speed IV Groudon is actually a high-value asset for Trick Room teams or for winning the weather lead battle.
- Prioritize Signature Moves: Do not settle for Hydro Pump or Earthquake. Origin Pulse and Precipice Blades are non-negotiable for top-tier performance.
- Master the Primal Timing: In Pokémon GO, don't "Primal Evolve" both at once. Alternate them to maximize the Candy XL bonuses you get for catching same-type Pokémon.
- Diversify Your Coverage: Kyogre needs Thunder to deal with other Kyogre. Groudon needs a way to hit Flying types (like Stone Edge or Rock Slide) because they are immune to its strongest Ground moves.
These two aren't going anywhere. Whether it's a remake, a new competitive regulation, or a massive global event in Pokémon GO, the duo from Hoenn will always be at the center of the storm. Literally.
