→Differences between Colosseum and XD
* The effectiveness of different purification actions in Colosseum is on average greater than the same actions in XD, but at the same time, the average magnitude of a Shadow Pokémon's full [[Heart Gauge]] is larger in Colosseum than in XD.
* Shadow Pokémon in the first game sometimes enter Hyper Mode, but in XD they enter Reverse Mode instead.
** In Hyper Mode a Pokémon may attack its Trainer, but in Reverse Mode, they will not.
** While in Reverse Mode, a Pokémon hurts itself after every turn, whereas a Pokémon in Hyper Mode incurs no self-damage.
* In Pokémon Colosseum, [[Shadow move]]s have neutral effectiveness against all types, but in Pokémon XD, Shadow moves are super effective on non-Shadow Pokémon and not very effective on other Shadow Pokémon.
