Shoulda shown darkspine sonic, but with really long hair, i say long hair because, sonic used 3 of the rings in SATSR, so i think that if he used all 3 he would have had SSJ3 hair, but darkspine color.
OMG Why hasn't this masterpiece gotten more views? o.o I love the idea of super saiyan 2 being Hyper sonic. XP But with super saiyan 3 sonic, I think the hair should have been a little longer. Nonetheless its an amazing animation.
