Pokémon Giratina Strikes Back

Pokémon Giratina Strikes Back is a FireRed hack set after the main game's events, when Giratina breaks through from the Distortion World to invade. This randomized version shuffles all wild encounters and trainer rosters while the dimensional invasion storyline plays out. Three seeds give you a different Pokémon spread across the routes and trainer hands during the crisis.

Giratina Strikes Back is a relatively short, complete hack, which makes the randomized version a quicker experience than randomizing a full mainline game. The dimensional invasion storyline adds urgency to every trainer battle, and with a randomized Pokémon spread on both sides, the conflict feels appropriately chaotic.
