A Hidden Ability is an ability that cannot be obtained through normal means. In the main series games, Hidden Abilities can be found in a number of way, but in Uranium, they can currently only be obtained by using the Poké Radar.
Despite the name, Hidden Abilities are not an extra ability present on a Pokémon that is unseen. A Hidden Ability still functions like any other ability, being seen on the summary screen of a Pokémon and being clearly seen in battle, such as when it activates or if a Pokémon switched abilities through Skill Swap. A Pokémon cannot have more than one ability at a time. For example, if a Titanice had Snow Warning, it would not receive the health restored by Ice Body, because it does not have both abilities.

Though these Pokémon have data for Hidden Abilities, they cannot be encountered in patches of tall grass, and so cannot legitimately have their Hidden Abilities.
