About This ROM Hack
Pokémon Delta Green (Zenon Returns) is a story-driven Pokémon LeafGreen ROM hack set in a future version of the Kanto region. While it begins like a traditional badge quest, the game quickly shifts into a darker, choice-based narrative involving Team Rocket, legendary Pokémon, and a mysterious antagonist known as Zenon.
The hack heavily reworks maps, events, difficulty balance, and story flow, making it feel nothing like the original Pokémon LeafGreen after the early game.
Story Overview
The story takes place several years after Pokémon LeafGreen. You begin your journey in Kanto with the familiar goal of earning Gym Badges and challenging the Pokémon League—but fate has other plans.
Rumors spread of Team Rocket regaining power and attempting to control a legendary Pokémon once sought by Giovanni. However, this Pokémon does not choose Giovanni as its master. Instead, it seeks to oppose a mysterious and dangerous human known as Zenon, whose actions are causing destruction across the region—particularly around Wilturf Silent.
You encounter Zenon early in the game, and from that point onward, events spiral into conflicts involving:
- Team Rocket’s resurgence
- Legendary Pokémon such as Mew and Celebi
- Moral decisions that affect your allies and encounters
Your choices will influence how the story unfolds—and even whether you side with Giovanni in the endgame.
Key Features
- Future Kanto Region: Explore a reimagined Kanto set in the future, with redesigned routes, towns, and dungeons. Unpopular or flawed maps and puzzles (e.g., Rock Tunnel, third gym puzzle, Fuchsia City) have been rebuilt for better gameplay.
- Increased Difficulty: The game is significantly harder than Leaf Green. Gym leaders, trainers, and AI strategies have been rebalanced to challenge advanced players.
- Side Quests and Player Choice: Participate in multiple optional events and side quests. Your choices influence encounters, story progression, and rewards.
- Companions: Brendan, May, and Rival (Terry) accompany you on your journey, providing battle support and interacting with story events.
- Expanded Pokémon and Moves: New Pokémon and moves are available. Starter Pokémon were balanced in Beta V1.1.4 (from Tyrogue-Teddiursa-Snubbull to Diglett-Magikarp-Ralts). Event Pokémon provide additional team-building options.
- New Storyline with Xenon: A new plot introduces Xenon as a central antagonist. Team Rocket’s plans and Legendary Pokémon play key roles, and player choices impact the outcome of the story.
- Quality-of-Life Improvements: Running Shoes now work in caves. Map layouts are optimized, and event triggers have been refined for smoother gameplay.
- Major Event Additions: Beta versions include new events like the Pewter City early starter event, altered Mt. Moon encounters, and a Big Event after obtaining all eight badges, rewarding completion of side quests.
