Step into Pokémon Go's PvP mode with the Ultra League Tier List. Choose your Pokémon, enter the arena, and dominate your opponents!

Ultra League is one of the most popular competitions in Pokémon Go’s PvP mode, GO Battle League. It is an open format like Great League and Master League, meaning there are no restrictions on the types of Pokémon that can participate. However, there is a maximum limit of 2,500 Combat Points (CP) for the Pokémon used in battles. Today, we have prepared the Ultra League Tier List 2023 for you. If you’re ready, let’s get started!

Ultra League Tier List 2023

Despite the noticeable impact of the balance changes in the Hidden Gems update on competition, Ultra League continues to remain quite stable overall. One significant change is the decline of Trevenant, which has dropped entirely from the top ranks. Considering the feedback from players based on the latest updates, we have created the Ultra League Tier List. Let’s get started!





Tier List Overview Criteria

  • T0: This is the highest tier in a tier list, reserved for the most powerful or effective options in the game. Characters or strategies in this tier are considered to be essential picks for competitive play and are often banned in tournaments.
  • T1: This tier is just below T0-tier and includes characters or strategies that are still very strong and effective, but not quite as dominant as those in the T0-tier.
  • T2: This tier includes characters or strategies that are considered to be average or balanced in terms of their strength and effectiveness. They may have some strengths and weaknesses, but they are not as dominant as those in the higher tiers.
  • T3: This is the lowest tier in a tier list, reserved for the weakest or least effective options in the game. Characters or strategies in this tier are often considered to be inferior to other options and may be rarely used in competitive play.

It’s important to note that the exact definitions and criteria for each tier can vary depending on the game and the community creating the tier list. Additionally, a character or strategy’s placement in a tier list is not always an accurate reflection of its overall strength or effectiveness, as factors such as player skill and game balance can also play a significant role.

Best Pokemons in Ultra League


With an absolute max CP of 2447, Registeel caps off right below the Ultra League maximum, meaning that it’s also expensive to prepare for Ultra League. Much like in Great League, the high energy gains from Lock-On allow Registeel to heavily pressure shields, and demands immediate answers for it. While it can narrowly beat Giratina-Altered Forme, the Origin Forme’s access to Shadow Ball allows it to deny Registeel’s total domination. Fighting-types are still a major weakness for Registeel, which are to be expected in this league as they naturally deal with the Dark-types who are meant to counter Giratina.


Giratina-O duels its Altered self for dominance of the Ultra League, and with good reason. Its stats are wonderfully set for the Ultra League, with strong damage output from Shadow Ball, and its typing is great. Its two forms have remarkably similar performance, though Giratina-A benefits from the coveted Dragon Claw and extra bulk. It’s a genuinely dangerous Pokemon, and in the off chance it gets a boost or two from Ominous Wind, it becomes even more frightening and deadly. Giratina-O also faces competition from the likes of Trevenant and Cofagrigus due to their similar movesets. Common Pokemon like Obstagoon, Mandibuzz, and Umbreon can completely shut Giratina-O down.


Swampert is very good for Ultra League partly thanks to the numerous Steel-types in the meta, in addition to the relatively few Grass-types compared to Great League. Dominance over many of the “anti-Giratina” picks which are mostly Dark-types and also Snorlax, in addition to numerous wins against counters to those picks (AKA Fighting-types), makes Swampert very appealing to use. It should also be noted that Swampert can tie or even narrowly beat Giratina Altered Forme depending on movesets and shielding scenarios, which would possibly make this Pokemon a 5/5, if it were not for the lack of consistency in that matchup. Earthquake is preferable in Open Ultra to give you a strong neutral hit against Giratina, whereas both Earthquake and Sludge Wave are viable in Ultra Premier.


Charizard’s devastating moveset allows it to perform well in the Ultra League, shredding even the sturdiest Pokemon with repeated Blast Burns. Risky vulnerabilities and unspectacular bulk are still major problems for Charizard though. Access to Dragon-type moves is valuable against popular Dragon-types like Giratina.


Much like in Great League, Zygarde-C continues to possess insane bulk in the Ultra League – enough to tower over even Giratina. It possesses the tools to dismantle some of Ultra League’s finest tanks – Earthquake keeps Registeel and Galarian Stunfisk at bay, Crunch can make Cresselia think twice before about challenging it, and its STAB Dragon Tails (and Crunch, again) can topple over Giratina. To illustrate Zygarde-C’s tankiness, it is bulky enough to cleanly avoid getting 2HKOed by Cresselia’s Moonblast after some Psycho Cut chip, something that Giratina struggles with. All in all, Zygarde-C is poised to become a metagame-defining threat the moment that a player successfully collects the Cells necessary to transform it. That said, this beast still deeply struggles against Fairy- and Ice-type Pokemon, so Pokemon such as Tapu Fini, Walrein, Alolan Sandslash, and Alolan Ninetales are key to defeating it safely.

Galarian Stunfisk

The lv50 update boosts Galarian Stunfisk’s max CP to 2445, and goes just under the CP cap of Ultra League when it becomes your Best Buddy. This makes it ideal for Galarian Stunfisk to shine in this league, with all the perks it enjoyed in Great League now against the Ultra League meta. Fast energy gains, wide and powerful coverage, numerous resistances, and huge bulk all contribute to this Pokemon’s success in the meta. All for the price of a ton of XL candy.


Jellicent is incredibly powerful in both open Ultra League and Premier Cup formats. With strong neutral coverage that’s largely unresisted, in addition to its useful resistances, Jellicent stands to challenge much of the meta in a big way. Only a handful of Pokemon can comfortably beat Jellicent, including Snorlax, Alolan Muk, Gengar, and various Grass-types. Hex is recommended for Ultra League, though Bubble helps flip the matchup vs Obstagoon. Overall a very strong pick, with the biggest drawback being the amount of XL candy needed.


The Lv50 update greatly improves the performance of Deoxys Defense Forme in Ultra League, transitioning all of the perks it enjoyed in Great League to Ultra League. The steep XL costs might be worth it for competitive players due to the additional options that only Deoxys Defense Forme provides in this league. Medicham cannot reach the CP cap of this league, and no other meta Psychic-type has access to the powerful Fast Move Counter, in addition to the relatively unique coverage that Deoxys provides. Gallade, Mew, Hypno, and Armored Mewtwo have Fighting-type coverage, but only in their Charged Moves, while actual Fighting-types don’t provide resistances to both other Fighting-types and Psychic-types that Deoxys boasts. Overall a very strong contender now that XL is a possibility, though popular picks like Giratina and Cresselia help keep it in check.
