I have no idea what the brand is. I bought it at some expo in a clear bag along with other similar figures. They all had a circular plastic base with the 'Z' symbol on it, if that helps.

For my fellow canadian collectors, amazon.ca has Goku Warrior Awakening Version for under $43+tax with free shipping.
They've also got sales on some of the newer effect pieces (aura and wave).
