Spira

Spira is a boss spawned with the Spira's Call. It is the final boss of Spirabox, and takes its name from it. Defeating it for the first time grants the player the A Savior achievement. On Challenge Mode, after losing all HP, Spira changes into his True Form, gaining more HP and obtaining new attacks.
