Generation 9 UU — Singles Format Reference

Gen 9 UU is the second tier of the Smogon usage hierarchy. Pokémon below OU's usage threshold play here, supplemented by UUBL drops too strong for UU. The format runs faster and more polarized than OU.

Defining list

UUBL

Take OU's top 25% of usage off the table. What plays at the next 25% is UU — faster on average, more polarized, less defensive depth, more priority abusers.
— The UU structural fact

At a glance

UU is the usage tier directly below OU. Pokémon drop into UU when their OU usage falls below the tier's threshold; Pokémon rise to OU when their UU usage exceeds OU's lower-end threshold. The cycle produces continuous mid-tier movement.

UU runs the same Smogon clause set as OU plus a tier-specific UUBL banlist for Pokémon too strong for UU but not used enough for OU. The format's defining feature is its pace — fewer wallbreakers absorb Choice Band hits, fewer reliable defensive walls anchor stall, and priority moves cover more matchups than in OU.

Format rules

UU applies the standard Smogon Singles clauses identical to OU, plus the UUBL ban list. The format's structural identity flows from which Pokémon are NOT in OU vs which are NOT in UU.

UUBL & the tier system

The Smogon usage tier system is the franchise's primary self-balancing mechanism. UU's banlist is dynamic — Pokémon move between OU, UU, and RU based on usage trends.

How tier shifts work

  • Drops — when a Pokémon's OU usage falls below the tier threshold for several consecutive months, it drops to UU.
  • Rises — when a Pokémon's UU usage rises above the OU threshold for several months, it rises to OU.
  • UUBL — if a Pokémon's UU usage indicates it's too strong for the tier (high win-rate, high usage) but not used enough for OU, it's placed in UUBL — banned from UU but not legal in OU.

UUBL examples

UUBL is dynamic — exact members shift across cycles. Common UUBL residents in Gen 9 have included variants of Roaring Moon, Iron Valiant, and other OU drops that proved too strong for UU. The current UUBL list lives on Smogon's tier page.

Archetypes

UU archetypes mirror OU's but with different defining Pokémon. Hyper Offense, Balance, and Stall all viable; weather teams less central; speed-control via priority more common.

Aggressive

Hyper Offense

Six offensive Pokémon. Common build: hazard-stack lead + Choice Band wallbreaker + Choice Specs special breaker + setup sweeper + priority cleaner + endgame closer.

Balance

Bulky Offense

3-4 offensive Pokémon plus 2-3 defensive pivots. UU defensive cores: Rotom-Wash, Slowking variants, Skarmory drops, Sylveon Wish-pass.

Defensive

Stall

Six defensive Pokémon. Stall in UU works around Sylveon Wish, Skarmory Spikes, Rotom-Wash defensive support, plus a stallbreaker (Hatterene equivalents or progressive wincons).

Specialty

Sand · Rain niche

Without OU's top weather setters (Tyranitar usually OU), UU weather teams use alternative setters and rely on the speed boost more than chip damage.

Setup

Setup spam

UU rewards setup sweepers. Calm Mind users, Dragon Dance setters, Swords Dance physical breakers — fewer reliable revenge killers means setup wincons close games.

Priority

Priority offense

Bullet Punch, Aqua Jet, Sucker Punch users get extra value in UU. With fewer Choice Scarf revenge killers, priority moves cover speed control gaps.

Team roles in UU

The seven structural roles apply identically to UU. The Pokémon filling them are different from OU — typically lower-stat-line versions or niche Pokémon that didn't crack OU.

1. Hazard setterStealth Rock + Spikes / Sticky Web

UU hazard setters: Skarmory (when OU-dropped), Salamence Stealth Rock, niche Sticky Web setters.

2. Hazard controlRapid Spin / Defog

UU removers: Rotom-Wash Defog, niche Rapid Spin users (Sandaconda, etc.). Spinblockers fewer in UU than OU.

3. Speed controlChoice Scarf / priority

UU speed control leans on priority more than OU. Common Choice Scarf users: Salamence, Rotom variants, niche threats.

4. Status absorberMagic Guard / Natural Cure

Sylveon + Heal Bell / Wish, niche Magic Guard absorbers.

5. PivotU-turn / Volt Switch / Teleport

UU pivots: Rotom-Wash Volt Switch, Salamence U-turn, niche Teleport users.

6. WallbreakerChoice Specs / Choice Band

UU breakers: Specs special attackers, Banded physical attackers. Lower stat lines than OU but still effective in UU's defensive context.

7. Win conditionSetup sweeper / progressive

UU wincons: Calm Mind setup, Dragon Dance setters, Sword Dance physicals, Iron Defense + Body Press niche.

What makes UU different

UU is OU's structurally faster, more polarized cousin. Without the format's top-tier defensive walls, offensive Pokémon cycle through KOs more quickly.

Setup viability

Setup sweepers close games

  • Faster pace — without OU's defensive cornerstones (Toxapex, Garganacl etc. typically OU-staple), wallbreakers exploit lower defensive ceilings more reliably.
  • More setup viability — fewer reliable revenge killers means setup wincons cycle to +1 / +2 more easily.
  • Priority bracket matters more — Bullet Punch, Sucker Punch, Aqua Jet, Mach Punch users get extra value relative to OU.
  • UUBL volatility — the tier's banlist shifts more than OU's. Pokémon drop, get UUBL'd, sometimes return.

How to get started

UU has a smaller community than OU but an active ladder and dedicated tournament scene. The faster pace makes ladder games shorter than OU.

  1. Read Smogon's UU tier page — banlist + UUBL list canonical.
  2. Pick an archetype — UU rewards setup spam and HO; balance and stall work but require tier-specific defensive knowledge.
  3. Copy a sample team — Smogon's UU samples are vetted; tier shifts make them rotate, but baseline structures stay valid.
  4. Ladder Pokémon Showdown — UU ladder is active. Tournament play continues via Smogon UU Open and similar.
  5. Track tier shifts — UU's usage cycle moves Pokémon every few months. Stay current via the tier page.
