The Bakunawa is an ancient superweapon that belongs to Merga, who plans to resurrect and use against the Three Kingdoms of Avalice, not only in an act of vengeance against the Avalicians, but as part of her plan to "Purify the World". The Bakunawa appears to have a mysterious connection to the late Princess Cordelia and the island chain of Parusa.
The Bakunawa will also be the Final Stage in Freedom Planet 2, and may possibly be called "Bakunawa Finale". Like Final Dreadnought, will be divided into a Round Stage Set; except there will be 3 Rounds instead of 4.
- Bakunawa is named after a Mythical Sea Dragon of the same name, and is also known as the "Mooneater". This is one of many references to the Philippine Culture in Freedom Planet 2.
- The name Bakunawa is believed to originally be a compound word meaning "Bent Snake", from Post-Western-Mayalo-Polynesian *Bakuq ("Bent", "Curved" ) and *Sawa ("Large Snake", "Python" ), which makes sense, given it's snake-like appearance.
