Gen 9 Ubers is Smogon's format for Pokémon too strong or too centralising for OU. It includes box legendaries like Miraidon and Koraidon, Mythicals, and other powerful Pokémon banned from lower tiers. Battles are 6v6 singles with Terastallization legal. Ubers has its own banlist — a small number of Pokémon like Mega Rayquaza are banned even from Ubers.
Top Gen 9 Ubers threats include Miraidon, Koraidon, Calyrex-Shadow Rider, Zacian-Crowned, Kyogre, Groudon, and Yveltal. Support Pokémon like Arceus-Water, Arceus-Fairy, Ho-Oh, and Lugia are also common. Miraidon and Koraidon are the most dominant Pokémon in the tier due to their field-setting abilities and raw power.
Gen 9 Ubers allows Pokémon banned from OU, including all box legendaries, Mythicals, and strong Pokémon like Flutter Mane and Chien-Pao. The power level is much higher, battles are more centralised around a handful of top threats, and defensive play looks very different with Arceus formes as the premier walls.
Most competitive Ubers teams are built around one of the dominant restricted Pokémon — Miraidon, Koraidon, or Calyrex-Shadow. Pair your primary attacker with support like Arceus-Water or Arceus-Fairy for defensive backbone, a hazard setter, hazard removal, and a speed control or revenge killer. Check the sample teams above for current top-tier Ubers structures.
Even in Ubers, a small number of Pokémon are banned as "AG" (Anything Goes). This includes Mega Rayquaza (which can bypass standard Ubers clauses) and others that make the format unplayable. Abilities like Shadow Tag and moves like Moody are also banned under standard Smogon clauses.
