<p>There are 2 things that make the Manga version a more "stable" version, first in that Zamasu learned about Goku from Shin, and second, that Shin was Probably visiting Zamasu without any interference from Future Trunks, since he appeared at about the same time they were visiting Zamasu.

<p>So Zamasu created Black in the future because of Goku, right? But, we know that Goku died in the future because of an illness... a long time before he met Zamasu. </p>

<p>So how is it possible that Zamasu knows Goku in the future? </p>
