Pokémon-ex are a special kind of Pokémon found in the TCG. They first appeared in the EX Ruby & Sapphire expansion.

The ex in the name stands for extra, as indicated by a wide range of attacks that have some sort of additional effect on Pokémon-ex. For example, in the EX Deoxys expansion, there is a Grumpig card which possesses an attack called "Extra Ball", which deals additional damage if used against a Pokémon-ex.

The major difference between Pokémon-ex and other types of Pokémon is that when a Pokémon-ex is Knocked Out, two prize cards are taken, as opposed to the standard one. To compensate for this downside, Pokémon-ex are significantly stronger than other types of Pokémon. In the EX Ruby & Sapphire expansion, Pokémon-ex were basic Pokémon with relatively powerful attacks, however in all following expansions, they have taken on a number of other traits. Pokémon-ex may have up to two Weaknesses or Resistances and a Retreat Cost of up to five. Their HP is also not bound by the traditional 120 HP limit on all other types of card, the highest so far being found on Wailord ex, at 200 HP. Additionally, they are immune to certain effects, for example their Poké-Bodies are not deactivated by Space Center (EX Deoxys), but they are also excluded from the benefits of certain cards, such as Sitrus Berry (EX Unseen Forces), which cannot be attached to them. There are also certain cards that only affect Pokémon-ex, nearly always negatively. The most well known example would be Desert Ruins (EX Hidden Legends), which requires each player to put a damage counter on each of their Pokémon-ex with a maximum HP of 100 or more between turns.

Being a Pokémon-ex affects a Pokémon's name, so Blissey cannot evolve from Chansey ex. However in EX Unseen Forces, Blissey ex had text allowing it to evolve from either Chansey or Chansey ex. This also occured with Scizor ex. However, Rocket's Scizor ex is only capable of evolving from Rocket's Scyther ex, not Rocket's Scyther.

Many Attacks, Poké-Powers and Poké-Bodies on Pokémon-ex are similar or identical in effect to those found on previous cards of the same species, allowing players to continue using popular strategies and tactics while avoiding the need to reprint cards.
