A signature ability is an ability that can only be possessed by members of one evolutionary line.

With the large number of abilities in the main series games and the comparatively small number of Pokémon in Pokémon Uranium, it is not uncommon for a canon ability to be exclusive to one line in Pokémon Uranium despite multiple Pokémon having it in the official games. Due to the large number of such instances, these abilities will currently not be included in this list.

  • Though not signature abilities in the main series games, Drought, Drizzle, and Sand Stream all only have one evolutionary line that can obtain the ability in Uranium. This means the only weather-summoning ability that can be obtained by multiple Pokémon is Snow Warning.
