Upd: Pokemon Gym Leader Simulator

We’re currently coding the Elite Four Invasion event. Once a month, a rogue AI controlling Lance’s Dragonite will attempt to "audit" your Gym. If you beat him, you get a golden statue outside your building. If you lose? He deletes your Gym’s theme music and replaces it with a 10-hour loop of the Poké Flute.

Patch 0.8.0 goes live this Friday at 6 PM GMT.

As always, you can wishlist the game on Steam or join our Discord (link in bio). If you find a way to break the new gravity panels, please report it. If you find a way to use the gravity panels to softlock a kid into surrendering out of frustration? That’s not a bug. That’s strategy.

Get your badge polish ready. The challengers are getting smarter.

P.S. Yes, we added Shiny Pokémon. No, you cannot set your ace as a Shiny unless you beat the game on Hard Mode. Stop asking.

The latest update for the Pokémon Gym Leader Simulator has arrived, bringing a massive overhaul to how players design, manage, and defend their custom Gyms. Whether you are a veteran strategist or a new challenger, this update introduces features that bridge the gap between creative building and competitive battling. What’s New in the Latest Update?

Custom Room Hazards & Terrain: You can now set permanent Entry Hazards or Terrain (like Electric or Psychic) that trigger the moment a challenger enters the field.

The "Legacy Leader" Boss Rush: A new PvE mode where you can test your custom Gym layout against AI versions of iconic Leaders like Brock, Misty, and Blue.

Advanced AI Customization: Program your Gym "Minions" with specific behaviors, such as prioritizing status moves or switching out when at a type disadvantage.

Enhanced Badge Designer: A revamped UI for creating your custom Badge, now featuring metallic textures and animated particle effects for when challengers win. Mastering the Simulator

To make the most of this update, focus on the new Synergy Mechanics. The simulator now rewards "Thematic Cohesion"—if your Pokémon, Gym layout, and Badge design all align with a specific Type or strategy (like a Rain Dance team in a water-themed Gym), your defenders receive a small stat boost during NPC invasions. Community Sharing & Leaderboards

The update also streamlines the Gym Code system. You can now export your entire Gym setup as a single string of text to share on forums or Discord. High-ranking players on the global leaderboard now earn "Prestige Points," which unlock exclusive furniture and rare Pokémon skins for their Gym's aesthetic.

The concept of a " Pokémon Gym Leader Simulator " centers on the fantasy of running your own gym, managing staff, and defending your title against rising trainers. While often found as fan-made games or Roblox simulations, the "story" typically follows a common narrative arc. The Rise of a Specialty Leader

The story usually begins with you as a veteran trainer or a promising apprentice taking over a fledgling gym in a new region. Unlike a standard journey, your goal isn't to collect badges but to curate them.

Choosing Your Type: You must specialize in a single type (e.g., Ghost, Steel, or Dragon), which dictates your Gym's aesthetic and team composition.

Building the Infrastructure: The "Update" (UPD) aspect of these simulators often involves upgrading your gym from a simple room to a complex gauntlet filled with puzzles, traps, and junior trainers to test challengers.

The Challenger Loop: You encounter a variety of NPCs—from "Youngsters" with basic teams to "Ace Trainers" with competitive strategies. Each victory earns you resources to improve your facility. Key Narrative Elements

The Power Level Paradox: As a leader, you must balance being a "gatekeeper" and a "teacher." You often maintain multiple teams of varying levels to match the number of badges a challenger already possesses.

The Elite Challenge: The endgame usually involves defending your gym against the Regional Champion or rival leaders looking to prove their type is superior.

Management & Reputation: A major part of the story involves building your gym's prestige. High prestige attracts more skilled challengers and unlocks rarer TMs and held items for your Pokémon.

If you are looking for a specific fan game, players often recommend checking YouTube showcases of gym leader fan projects to see the latest "UPD" features like mega-evolutions or custom badge crafting. Pokémon, BUT you play as a Gym Leader

Have you played the new update? What is your Gym Leader persona—are a benevolent teacher or a ruthless tyrant? Let us know in the comments! Enhancements


This is the biggest "Simulator" addition. You aren't just battling; you are managing a brand.

You can now create one "Gym Signature Move." For example: Boulder Breaker (Rock-type, 70 BP, but it raises your Defense by two stages if the opponent misses). This move is tied to your Gym, and challengers see its name but not its effect until it hits them.
