Roblox NPC Generator — Create Custom NPCs with AI
Describe any character — wizard merchant, stone golem boss, space marine guard — and get a fully textured 3D model ready to import into Roblox Studio.
NPCs bring your Roblox game world to life. A medieval marketplace without merchants, a dungeon without guardians, a space station without crew — these worlds feel empty. Custom NPCs designed to match your game's theme make everything feel more intentional.
PromptBlox generates NPCs as standalone 3D mods. Describe the character, get a textured model, import it into Studio, and add the behavior scripts (dialogue, patrol, attack) on top. The AI handles the visual design — you handle what the NPC does.
Types of NPCs You Can Generate
Merchants & shopkeepers
A town blacksmith, magical potion seller, or floating robot vendor. Add a ProximityPrompt and shop GUI in Studio.
Guards & soldiers
Castle guards, space marines, dungeon sentinels. Great for decorating your map and adding patrol scripts.
Bosses & enemies
Giant stone golems, dragon knights, alien commanders. Use as end-stage enemies or area bosses with combat scripts.
Quest givers
Wise old wizards, mysterious strangers, oracle characters. Add dialogue GUI scripts in Studio.
Creatures & monsters
Goblins, zombies, giant spiders, alien drones. Perfect for survival or adventure games.
Friendly characters
Guides, tour NPCs, cheerful robots. These are great for new-player onboarding areas.

Frequently Asked Questions
Does the NPC have movement or dialogue built in?
NPC mods are 3D models. Behaviors like patrol paths, attack scripts, and dialogue GUIs are added in Studio. The Roblox Toolbox has free NPC AI scripts, or check the Roblox documentation for pathfinding and ProximityPrompt examples.
Is the NPC sized like a Roblox character?
Generated NPCs are scaled to approximately Roblox character size by default. You can rescale them freely in Studio — great for making giant bosses or tiny minion enemies.
How much does an NPC cost?
Standard NPC mods are 10 credits. Deluxe (higher mesh detail) are 20 credits. Your first generation is covered by signup credits, with an optional 100-credit Discord bonus after manual review. See pricing.
Can I generate multiple NPCs for the same game?
Yes — generate as many as you need. Use the same style words across all your NPC prompts to keep a consistent visual theme throughout your game.
