Good idea but...
*NOTE TO ANIMATOR*
This is a very good idea. It’s plausible. But you need to add more detail. In the story. Like how did he confront Goku? And at first it seemed like the story was taking place right after the Freeza saga. Then Goku could turn ssj3??? It’s a little confusing. But the story is still good. I have an idea for let me know what you think. How about Xeon fights Goku on that planet he crashed on but Xeon loses and Goku thinks he killed and that’s why he never spoke of this fight. But years later when Goku can turn ssj3, Xeon comes back and has a few new tricks up his sleeve. Keep up the good. You have talent.
