About This ROM Hack
Pokémon Korosu is a darker, more mature Pokémon hack that focuses on revenge, violence, and a grim Kanto/Sevii setting. It is set in the same universe as Pokémon Outlaw, with references to its events, but it is fully playable as a standalone story.
The hack combines nostalgic Pokémon mechanics with modern elements, including a Physical/Special/Status split and select Gen IV–VI Pokémon. Players will experience two regions: the crime-ridden Sevii Islands and a grim, post-Outlaw Kanto.
Story Overview
The protagonist is a young woman whose family has been murdered and who has been kidnapped by a mafia-like criminal group. She escapes and embarks on a journey of revenge against those who ruined her life.The story unfolds in two parts:
- Sevii Islands: Controlled by criminal factions; early-game story focuses on survival and revenge.
- Kanto: A post-Outlaw region in chaos; the sequel storyline continues with new challenges and darker events.
Key Features
- Physical/Special/Status split for modernized battle mechanics.
- BW2-style repel system – prompts to use another repel when one expires.

- Shinx and evolutions, Leafeon, Glaceon, Roserade, Weavile, Gallade, Lucario, and others.
