The answer is simple for me xD because Vegeta is my favorite character, so I would see his mother, just to know everything about him and his past.

My second choice would be Goku's mother. We saw 2 specials about his father, but nothing about his mother. Why? Where was she during the story about Bardack? Goku is the main character, I think could be important to see all his origins.

I'm curious also about Goku JR's mother and his family overall.

Some of these pics are genderbents of dbz characters. Shorotto is not Goku's mom. She was made up by a deviantart User.

I know it. I've put these images just to make this poll nice. I'm perfectly conscious that all of these pictures are fanarts (except the screenshot of old Pan and Goku JR) and that's the reason I chose them. The poll should be empty and banal without pictures, don't you think? And about the genderbents... I didn't find any fanart about Yamcha and Ten's mother, so I thought that the genderbents could represent their mother the best.

Anyway, it's specified "mothers who never appeared during the story" and, since they don't appear, I can't have a screenshot of them XD So, I used fanarts :D

If you want to choose who is the best (seen) mother, you can pick here:
