Monster Catcher Battle System for RPG Maker MZ — Complete Sample Project

Monster Catcher Battle System for RPG Maker MZ — Complete Sample Project

Turn RPG Maker MZ into a full monster-catching RPG. This is a complete, ready-to-run creature-collector battle system for RPG Maker MZ — 35 tightly integrated plugins plus a working sample project you can open and play in minutes. Wild encounters, catching, type effectiveness, IV/EV/Natures, evolution, trainer battles, a PC storage box, a MonsterDex, a Monster Mart, day/night, weather, and image-based menus are all built in.

You focus on your monsters and maps — the systems are already done.

NOTE: All graphical assets included in the sample project are meant to be used as placeholders only. You must replace them eventually with your own assets before distributing your game.

▶ Why buy this?

✅ Everything works together out of the box. 35 plugins, one correct load order, zero setup guesswork — the sample project is already configured.

✅ Fully customizable. You can replace every asset with your own. You can also adjust the position and size of every asset. All settings live in the Plugin Manager parameters.

✅ No coding required. Build monsters, moves, and items using simple notetags in the normal RPG Maker database.

✅ Beginner-friendly documentation included — a full HTML guide with copy-paste examples for every feature, notetag, and plugin command.

✅ Made as Actors, not Enemies — your monsters use MZ's real level curves, so stats, EXP, and evolution behave exactly how you'd expect.

✅ Commercial-use license included. Ship your game and sell it.

▶ Full Feature List

Region-painted wild encounters with per-map monster pools and level ranges.

Full day/night cycle with screen tint and glowing map lights (lamps, windows, fire).

Weather system — fixed or weighted-random per map, or triggered by item/command.
