Pokémon Ultra Sun remains one of the most challenging and rewarding entries in the franchise, even years after its 2017 release on Nintendo Switch. Whether you’re tackling your first playthrough or aiming for post-game mastery, the gameplay demands strategy, team building, and knowledge of mechanics that separate casual players from veterans. This guide covers everything: your opening moves in Alola, the infamous Ultra Necrozma spike, optimal team composition, catching mechanics, and late-game Battle Tree dominance. By the end, you’ll understand the depth of Pokémon Ultra Sun gameplay and how to approach every encounter with confidence.
Key Takeaways
- Pokémon Ultra Sun gameplay demands strategic team building with balanced roles: prioritize one physical attacker, one special attacker, one defensive wall, and one support Pokémon to handle diverse encounters.
- Ultra Necrozma is the game’s signature difficulty spike and requires specific counters like Chandelure or Gyarados paired with full restores and proper EV investment to overcome.
- Optimize your team with type coverage across four different types as main attackers, priority moves to bypass Totem stat boosts, and strategic TM usage to enhance movesets beyond standard STAB moves.
- EV training from level one and breeding for perfect IVs create a measurable advantage in competitive play and Battle Tree streaks, though casual playthroughs remain viable without this investment.
- Master post-game content like the Battle Tree and Ultra Wormhole by using competitive held items, strategic switching, and team redundancy to handle increasingly difficult opponents and earn endgame rewards.
Getting Started: Your First Steps in Alola
Your Pokémon Ultra Sun journey begins the moment you set foot on Melemele Island. The early game is deceptively manageable compared to later content, but smart decisions now prevent grinding headaches later.
Start by picking your starter, Rowlet, Litten, or Popplio, knowing that all three are viable through the main story. Rowlet edges ahead for its typing advantage against Totem Pokémon, but don’t stress if you prefer another. Immediately catch a Pikipek in the first routes: its evolution into Trumbeak and Toucannon provides solid physical Flying-type coverage that carries you through multiple trials.
Don’t overlook Growlithe on Route 1 (Ultra Sun exclusive). Fire-types are rare early, and having one prepared before the Kiawe trial saves time and resources. Similarly, grab an Abra when you reach Route 3, teleporting around Alola later becomes invaluable.
Sos Battles are your secret weapon for early training. When a wild Pokémon calls an ally, defeating the ally (not the main Pokémon) nets extra EXP and improved item drops. Use this to level up your team faster than traditional grinding. Your team should hit level 15–18 before each Totem battle: being underleveled forces reliance on luck instead of strategy.
Catch one Magnemite before the Totem Wishiwashi trial. Its typing and defensive bulk counter multiple threats. By the time you’ve cleared the first two islands, your team should include a Water-type, Electric-type, and physical attacker minimum.
The Ultra Necrozma Challenge: What Changed From Sun and Moon
If you’ve played the original Sun and Moon, Ultra Sun’s difficulty feels like a different game entirely. The Totem Pokémon have stat boosts, Pokémon have optimized movesets, and the level curve climbs steeply. But the real wall? Ultra Necrozma.
This legendary encounter is infamous for a reason. You’ll face it around level 60 as a Totem Pokémon with attack and special attack boosts active. In the original Sun and Moon, Necrozma wasn’t present. Ultra Necrozma was added as the game’s signature difficulty spike, designed to punish unprepared teams and reward strategic planning.
Ultra Necrozma Battle Strategy and Weaknesses
Ultra Necrozma uses a physical moveset with Photon Geyser (STAB Psychic), Close Combat (Fighting), Earthquake (Ground), and Swords Dance (stat setup). Its dual Psychic/Steel typing means it has exactly four weaknesses: Ghost, Dark, Fire, and Ground.
Your team should include at least one Pokémon covering these gaps. A Chandelure (Ghost/Fire) is ideal, it hits both weaknesses and resists Psychic. Alternatively, a Gyarados with Dark-type moves or an Earthquake-capable Ground-type works. The key is having a backup if your primary counter faints.
Three strategies dominate this fight:
-
Stall with Durable Walls: Use Toxapex or Umbreon with Curse or status moves. Ultra Necrozma has limited PP for Swords Dance and Close Combat. If you can survive until it runs out, you win by attrition.
-
Outspeed and Nuke: A Choice Scarf user or naturally fast Pokémon like Alakazam can outspeed (yes, outspeeding Necrozma is possible with proper EV investment) and strike before it uses Swords Dance. One or two hits from a super-effective move ends it.
-
Defensive Pivoting: Switch in and out with Pokémon that resist Photon Geyser and Close Combat. Assault Vest holders mitigate special damage, while physical walls tank Close Combat repeatedly.
Bring Full Restores and Full Heals to this battle. Items matter as much as team composition. Consider using a Pokémon with Light Screen or Reflect to reduce damage across your team.
New Pokémon Encounters and Availability
Ultra Sun introduces expanded Pokédex availability compared to the original. The Ultra Wormhole mechanic throws Pokémon from every generation at you, but specific encounters are locked to each game version.
Ultra Sun exclusives include Guzzlord, Buzzwole, and access to more Pokémon from Routes and trials. Ultra Moon gets Pheromosa, Xurkitree, and different distributions. If you’re targeting specific legendaries for competitive play, confirm availability before restarting.
Totem Pokémon have improved movesets. Where original Sun featured relatively standard moves, Ultra Sun’s Totems use coverage moves and items. Example: The Totem Araquanid in Ultra Sun carries Aqua Jet (priority), Swords Dance, and sometimes a berry to recover HP. This changes how you approach each trial.
Encounter rates for common Pokémon shifted slightly. Growlithe appears less frequently but is guaranteed on Route 1 (Ultra Sun exclusive). Magnemite availability expanded, making electric coverage more accessible. Plan your catches based on these shifts if you’re optimizing for specific types.
Building Your Winning Team Composition
Your team’s success hinges on type coverage, stat synergy, and role allocation. Pokémon Ultra Sun doesn’t reward balanced teams as much as specialized ones.
Every team needs:
- One physical attacker (handles physical walls and bulk)
- One special attacker (covers special walls and frail opponents)
- One wall or defensive Pokémon (survives crucial hits)
- One utility/support Pokémon (screens, pivots, status moves)
- Two flexible slots for coverage, priority, or situational counters
This distribution ensures you’re prepared for any encounter. A team of six pure sweepers crumbles against Totem Pokemon that gain defensive stat boosts.
Best Pokémon for Each Island Trial
Island 1 (Melemele): Grab Rowlet, Pikipek, and Growlithe. The Totem Gumshoos is slow and physical: any Pokémon with Water-type moves or decent defense handles it.
Island 2 (Akala): Add a Water-type like Magikarp (evolve before the trial) or Wishiwashi. The Totem Wishiwashi trial is the first real test of team synergy. Have someone that can heal and someone that can hit hard.
Island 3 (Ula’ula): A Flying-type becomes essential. Toucannon or Trumbeak if you caught Pikipek early, or catch Oricorio (pure-typing coverage Pokémon). The Totem Salazzle uses Fire and Poison coverage, bring Water or Ground-type moves.
Island 4 (Poni): By this point, finalize your team. You should have five core members and one flex slot. Level everyone to 55–60 for the champion battles. The final league opponents run optimized teams: underleveling guarantees losses.
Type Coverage and Move Pool Optimization
META reality: Pokémon ultra sun favors teams with four different types represented as your main attackers. This ensures you’re never completely walled.
Priority moves like Aqua Jet, Mach Punch, and Quick Attack matter more in Ultra Sun than casual games. Totem Pokémon move first when they hold stat boosts, so priority breaks through that advantage. Give at least two Pokémon on your team a priority move.
Coverage moves over STAB is sometimes correct. A Pokémon with mediocre STAB but excellent coverage moves (e.g., Close Combat on a Fire-type) often outperforms one locked into same-type moves. Example: Charizard gets Dragon Claw, Earthquake, and Close Combat via TM, making it hit more types than pure Fire moves alone.
Use TMs strategically. Ultra Sun’s TM availability is generous. Dragon Dance TM (increases Speed and Attack), Earthquake TM, and Flash Cannon TM are game-changers for otherwise mediocre Pokémon. Some players on Game8 note that creative TM builds often outperform traditional movesets.
EV and IV management matters even for casual playthroughs once you understand it. A Pokémon with perfect Attack EVs and IVs deals measurably more damage than one with random training. We’ll dive deeper into this in the catching section.
Catching and Training Mechanics You Need to Know
Pokémon Ultra Sun’s catching and training systems reward informed decisions. You can catch anything at any point, but optimal timing and knowledge accelerate your progress.
EV Training and IV Breeding for Competitive Play
EVs (Effort Values) are invisible stat boosts. Each Pokémon you defeat grants 1–3 EVs in specific stats. A Pokémon gains up to 252 EVs per stat and 510 total. Maxing Attack and Speed EVs (252/252) with four spare EVs in HP creates a classic physical sweeper spread.
In Ultra Sun, track your EV training from level 1. Catch a fresh Pokémon, level it exclusively against Pokémon that grant Attack EVs (like Pokémon with physical movesets), and you’ll have perfectly trained stats by level 50. SOS battles are ideal for EV farming since allies grant double EVs.
IVs (Individual Values) are permanent stats determined at capture. Perfect IVs (31 in relevant stats) are rarer and can’t be changed in Ultra Sun. Caught Pokémon rarely have perfect IVs: breeding is how competitive players guarantee perfection.
Breeding requires patience:
- Catch a Pokémon with high IVs (at least 25+ in Attack/Special Attack for physical/special attackers).
- Pair it with a Ditto (found in Ultra Wormhole or near the end-game) that has perfect IVs.
- Hatch eggs repeatedly until you get the right combination.
- Use an Everstone held by the parent to guarantee nature inheritance (nature affects stat distribution).
For casual players, this isn’t necessary. For competitive or Battle Tree runs, a perfectly bred Pokémon deals noticeably more damage, sometimes winning close encounters by killing before being killed.
Ultra Wormhole Pokémon and Legendary Hunts
The Ultra Wormhole is Ultra Sun’s endgame content. After beating the Champion, you unlock the ability to warp through multiple wormholes to catch legendaries and rare Pokémon unavailable elsewhere.
Each wormhole has:
- Distance (measured in light-years: longer = rarer Pokémon)
- Pokémon encounters specific to that distance
- Legendary encounters at extreme distances (1000+ light-years)
Plan your hunts. Guzzlord (Ultra Sun exclusive legendary) appears at specific distances and frequencies. Some players waste hundreds of wormholes on the wrong routes. Documentation on Gematsu tracks accurate spawn rates if you’re targeting specific legendaries.
Catching legendaries requires preparation:
- Bring a Pokémon with False Swipe to reduce HP safely.
- Pack Ultra Balls and Timer Balls (effectiveness increases with turn count).
- Have a Pokémon with a status move (Thunder Wave, Spore) to paralyze or sleep the target.
- Legendaries have higher catch rates in Ultra Sun than previous games, but preparation still matters.
The Ultra Wormhole grind is optional but rewarding. Competitive players hunt perfect IV legendaries here for ranked battles. Casual players enjoy the post-game content and collection completion. Either way, understanding the mechanics prevents frustration.
Battle Facility Strategies and Endgame Content
After defeating the Champion, Pokémon Ultra Sun transforms into a competitive proving ground. The Battle Tree and Battle Festival are where casual playthroughs become genuine tests of mastery.
Mastering the Battle Tree and Battle Festival
The Battle Tree is Ultra Sun’s primary post-game facility. You face trainers in single, double, or triple battles across 20-win streaks. Winning streaks earn BP (Battle Points), redeemable for items, TMs, and held items.
The first 20 wins feel manageable if your team is level 50+. But the difficulty curve is brutal. Trainers in win 21+ use competitive movesets, items, and perfectly trained Pokémon. Your team needs to match that precision.
Winning strategies for Battle Tree streaks:
-
Lead with a Taunt or Priority User: Opening with Taunt prevents opponents from setting up. Alternatively, Priority moves like Trick Room setters or Quick Attack users let you control the opening turns.
-
Use Held Items Strategically: Choice Scarf (boosts Speed by 1.5x), Assault Vest (boosts Special Defense by 1.5x), and Life Orb (boosts damage by 1.3x but causes recoil) are standard. Casual holds like Leftovers are weak here: competitive held items make the difference.
-
Team Redundancy: If your lead faints, your second Pokémon should cover its weaknesses. Don’t bring three glass cannons and hope to outspeed everything.
The Battle Festival is an alternative post-game facility with slightly different rulesets. Single battles are the most straightforward. Focus on Battle Tree wins first: Festival is bonus content once you’re comfortable.
Breaking through 50-win streaks requires near-flawless play. Even competitive players reset multiple times. The reward, rare held items and high-tier TMs, justifies the grind for players pursuing team perfection. Resources on Nintendo Life cover community strategies if you’re stuck on specific battle types.
Pro Tips to Optimize Your Gameplay Experience
These final optimizations separate efficient playthroughs from frustrating grinds.
Save before major battles. Totem battles and legendary encounters can go south fast. Saving before Ultra Necrozma, the final Champion battles, and legendary hunts prevents losing hours of progress to bad RNG.
Use the Exp Share wisely. Ultra Sun’s Exp Share (an item) distributes experience to all Pokémon. This is helpful for leveling multiple Pokémon simultaneously but can lead to overleveling. If you want a challenge, turn it off for Totem battles and re-enable it between islands.
Farm SOS battles early. The first few islands have abundant SOS battles. Use this time to farm EVs, catch perfect IV Pokémon, and level your team efficiently. Grinding later is slower and less rewarding.
Stock up on held items. Leftovers, Rocky Helmet, and Assault Vest are found or bought. Having held items equipped during story battles provides a hidden advantage that makes encounters noticeably easier.
Plan your moveset before battles. Mid-battle move changing isn’t an option. Know what your Pokémon will use. TM moves are customizable: plan coverage before major fights.
Nickname your Pokémon. It sounds trivial, but nickname your team. You’ll bond with them, remember their roles better, and the playthrough feels more personal. Plus, it prevents accidentally releasing your starter.
Exploit type matchups obsessively. Ultra Sun punishes type-neutral matchups. Every Pokémon you send out should have at least a neutral or favorable matchup. Switching out when at a disadvantage is smart play, not cowardice.
Understand Natures. A Pokémon’s Nature (determined at capture or breeding) boosts one stat and lowers another. Timid Nature (+Speed, –Attack) helps sweepers. Adamant Nature (+Attack, –Special Attack) helps physical attackers. Breeding with an Everstone held by the desired parent guarantees nature inheritance.
Conclusion
Mastering Pokémon Ultra Sun gameplay means understanding its systems, respecting its difficulty spikes, and adapting your strategy to each challenge. From your first steps in Alola to grinding Battle Tree streaks, every decision shapes your playthrough.
Start with the fundamentals: build a balanced team, prioritize type coverage, and level appropriately. Prepare ruthlessly for Ultra Necrozma and end-game content. Understand EVs, IVs, and held items, the invisible stats that separate victory from defeat. Most importantly, remember that Ultra Sun rewards planning and punishes carelessness.
Your journey through Alola is as rewarding as you make it. Play smartly, experiment with team compositions, and don’t fear resets, they’re part of the process. With these strategies and insights, you’re equipped to handle everything Ultra Sun throws at you.
