The Eco Disk is used by Daxter in jail break. It was also used by him in the final cutscene as a weapon of choice for destroying the gun in PlayStation Move Heroes.
Ecos Used[]
The Ecos used in the Eco Disk are most likely blue eco contributing to the speed, rotation, length of flight and color of the disk. Another eco used is probably red eco for the explosion that occurs during detonation. Lastly, the eco disk can be saturated with Dark Eco while Daxter turns into Dark Daxter causing the disk to send dark eco volts arching to any breakable object in range.
Trophies[]
