So why do I think that Sera and Lucifer take (not without some difficulty I admit, make Caesar give back what is Caesar's, Goku is strong) A/ The power of Sera and Lucifer 1 - Sera We could see in the flashback ep 1 s1 of Hazbin that sera was there creating the Earth with Adam and Lilith She therefore partially created everything that goes with it (so other planets like those of the Sayans in addition to all the other alternative universes found in Dragon Ball Super with a little luck) 2 - The power of Lucifer Lucifer, as you know, was kicked out of paradise in the evil he created because of having given the apple to Eve He therefore entirely with Lilith created hell in itself Conclusion: Lucifer and Sera create universes on their own And unless I'm mistaken, that's not something Goku can do. B/Goku Why couldn't Goku win against Sera and Lucifer? Already those who have read the DBS manga know that in the first volumes, Goku was even in SSJ 3 just to touch Berus (who is a god eh) and we know that angels such as Whis are stronger than the gods (and do you remember who else are angels? Lucifer and Sera) PLUS I'm on volume 18 of DBS currently (I know there are 2 or 3 more out but come on that won't change this reasoning) and Goku even in super sayan blue IS IN PLS FOR BEERUS and Whis) I can cite other examples pls eh there are no problems CONCLUSION Sera and Lucifer slaps Goku (PS : This reaonment is not mine, I debated in my side)
