Hyper Mode

Hyper Mode is a condition Shadow Pokémon will sometimes enter in Pokémon Colosseum. This is not to be confused with Reverse Mode, its equivalent in Pokémon XD: Gale of Darkness.

A Shadow Pokémon enters Hyper Mode during a Pokémon battle, and it will spend a turn having its emotions "rise to a fever pitch". Its status meter will turn red and black, and an aura of the same color will appear around the Pokémon, presumably only seen by Rui. When in Hyper Mode, the only move a Shadow Pokémon can use is Shadow Rush, which will have a raised critical hit ratio. If any other move is chosen, it may disobey and use another move instead. It may also turn at any time and attack its teammate instead. Items cannot be used on a Pokémon in Hyper Mode.

Hyper Mode can be ended by either calling to a Pokémon in battle, using a cologne on it, or leaving it at the Pokémon Daycare. Doing this will "open the door to its heart" a bit and bring it closer to being purified.
