Bills is out of the power scale. goku dies with ease
While SSJ4 didn't seem impressive feat-wise, if we were to believe Death Battle's numbers, SSJ4 should in theory be equal or even higher than SSJG. According to Death Battle(I don't know where they got their numbers), SSJ4 should be 10x as powerful as SSJ3, who Bills seemed to be kicking around with ease. And the best part about SSJ4, Goku doesn't have the short time limit that SSJG has. I am going to hold my judgement on which is stronger until I see some more feats for SSJG, or some official numbers come out.
Birusu kills him horibly.
didn't i say that death isn't allowed here. Only give up or unconscious.
Beside SSJ4 has long durability and has Dragon fist. He may weaker than SSJG during Shadow dragon saga but Bills may need to use 50% power to take him down. At the end of GT he also got huge zenkai boost after beating by Omega shenron. As we don't know how much he got stronger but according to the zenkai rules Bills have to use 80-90% power or even more. (Just guessing)
