Didn't Goku still have the ssjg power at the end of the movie with that and the various timeskips he should stomp Bills.
Don't be dense. GT is non-canon and SSG doesn't exist in the GT series. Numbers also prove the GT cast is vastly weaker than their DBZ selves. @taichokage
That I don't know, however, he would likely have been at least stronger than Omega Shenron in base since he absorbed his entire source of power plus his own on too of that.
Meaningless. The Shadow Dragons power came from Negative energy created by the wishes granted. The Dragon Balls at the end were Purified, that means there is no actual power left from the Shadow Dragons nor would Goku acquire them. Fans speculated Goku becoming a god in the future, which is irrelevant since he was already a God thanks to the recent movie, which has thrice proven the fact that GT is non-canon and never will be.
Nvm Word of God states the Twelve Gods of Destruction all being Universe-busters when at full strength, Birus openly stated he wasn't at his full power and needed to hibernate longer.
