## Abstract (arXiv)

Strategic decision-making in Pok'emon battles presents a unique testbed for evaluating large language models. Pok'emon battles demand reasoning about type matchups, statistical trade-offs, and risk assessment, skills that mirror human strategic thinking. This work examines whether Large Language Models (LLMs) can serve as competent battle agents, capable of both making tactically sound decisions and generating novel, balanced game content. We developed a turn-based Pok'emon battle system where LLMs select moves based on battle state rather than pre-programmed logic. The framework captures essential Pok'emon mechanics: type effectiveness multipliers, stat-based damage calculations, and multi-Pok'emon team management. Through systematic evaluation across multiple model architectures we measured win rates, decision latency, type-alignment accuracy, and token efficiency. These results suggest LLMs can function as dynamic game opponents without domain-specific training, offering a practical alternative to reinforcement learning for turn-based strategic games. The dual capability of tactical reasoning and content creation, positions LLMs as both players and designers, with implications for procedural generation and adaptive difficulty systems in interactive entertainment.
