The Enemy disc from Legacy Discs was PDGA Approved as of 8-25-2015.

"The ENEMY disc is Legacy's long awaited overstable driver. The ENEMY will offer a combination of speed and over stability. This disc will be the weapon to use in a head wind. The disc design was developed to have a comfortable feel with a deeper rim to give a player maximum torque. The ENEMY will be available in several plastic editions." - by Legacy Discs
