broly his power level will keep on rising forever and beat goku
He's more legendary, but not as powerful. Maybe SSJ4 Goku is, but that is not certain. He's definately more popular than Broly. The fusion of Goku and Vegeta, is immeasurably stronger than Broly though.
buu
No broly's maximum and only transformation is the legendary super saiyan form.
i think he might be cause the last time broly face goku he was only in ssj1 when they defeated him but he surpass ssj1 ssj2 ssj3 and is in ssj4 form so i think he would own broly
SSJ4 Goku, of course!
If Broly went SSJ4 he wouldn't be as strong as Goku or Vegeta. This is becasue in his base form he was considered weak, and in his second coming, his ssj form was weak enough for gohan to keep up with him without transforming. Broly's LSSJ form makes him really strong, and ssj4 is a base multiplyer which means it would multiply broly's base strength just as much as goku's base strength. I think a better question would be what if broly went LSSJ4 if there is even such a thing.
Omega shenron, because he has to be defeated by a super saiyan 4 fusion and broly is the basic super saiyan form, so if these two fought, broly would have to have fused with another super saiyan four.
no only....ssj1,ssj2,ssj3,ascended,legendary,ssj4
Goku easily
omega shenron ssj is dominated by broly id say that ssj2 would be about even so ssj3 would be able to beat him so ssj4 would probably dominate him and since omega shenron is stroger than ssj4 definately omega shenron unless broly went ssj4 or something
goku ssj4 is way stronger than kid buu because buu wouldn't defeat even a great ape which ssj4 would
SSJ5 Goku wins (if he wasn't in a battle then SSj4 Vegeta wins)
