In Freedom Planet 2, the heroes have to stand shoulder to shoulder with the heroes of Avalis to help them through the most dangerous and difficult challenge of their lives. An ancient evil has awakened from the depths of the ocean. The Realm Stone was destroyed, and Merga broke free — a water dragon that has not been seen since the bloodiest wars. The threat is very close, so the heroes must stick together to give a worthy rebuff and not be defeated due to disagreements.
