About Lethalmon
Lethalmon sends a prisoner into space to capture Pokémon on distant worlds after humanity has depleted Earth. Each run revolves around managing a limited step allowance while searching planets, with rarer and stronger encounters appearing further out. It suits players who enjoy repeatable roguelike runs, difficult choices and careful expedition planning. A central hub lets you sell caught Pokémon for money or keep them for battle, creating a trade-off when valuable partners appear. Money can alter natures, IVs and EVs, while other upgrades increase your movement allowance. Planets and gyms reshuffle between expeditions, and a shared Pokédex retains records across runs. Five badges open the route to the Pokémon League.
