Zamasu is back and worse than ever, only this time, he has Heart...s.
Bad joke aside, we now see that Zamasu has survived and aligned himself with the likes of Hearts. If you remember Baby from Dragon Ball GT, you will likely recognize Kamin & Oren. These were creations made by the Tuffles the same way Baby was made only instead, they were made in Universe 6 instead of 7. They appear to be twin brother and sister.
If you are confused, Hearts' main objective is to basically destroy Zeno. Yes, he wants to kill "God". Prison Planet was only made to source energy similar to when Babidi was collecting energy to release Buu. Only this time, it was in an attempt to create an entirely new universe. It is a lot to cram into these small promotional videos and I am honestly not a fan of throwing this much stuff out in only a small window of time but the characters are definitely interesting.
This can open up a lot of new stories for future series as well as some interesting backgrounds for a lot of new faces we have seen in Dragon Ball Super.
If you need/want an explanation for all these characters, just watch this video:
