Square Enix announced a partnership with Google to integrate Google's Gemini AI into the Japan-exclusive online RPG Dragon Quest X, creating an in-game companion character called 'Chatty Slimey' (Oshaberi Slimey) that can converse with players via text and voice. A closed beta test was announced in March 2026.

Chatty Slimey takes the form of the franchise's iconic Slime monster and is designed as a guide for new players who may feel lost in the long-running MMORPG. The AI analyzes information from the game screen and can initiate conversations when notable in-game events occur, such as defeating a powerful enemy or obtaining a rare item. Players interact with Slimey through a chat function, and the system automatically generates voiced responses using Google Gemini, including voice chat via Gemini Live. A closed beta test was announced in March 2026 with applications open through March 30, 2026.
