User blog:Imperial Wyrm/Dragon Ball Minus Power Levels

As you may know, Dragon Ball Minus does contradict the Bardock: Father of Goku special. The biggest problem would be that Goku is sent to Earth as a three year old in Dragon Ball Minus, while he is a few weeks old in Father of Goku. He is also much weaker in Bardock: Father of Goku. In my opinion, the anime and manga have similar but different canon. Father of Goku could be anime canon and Dragon Ball Minus could be manga canon. So, in the manga, Goku is really three years older than he'd actually be in the anime.

In Father of Goku, Bardock is stated to become almost as strong as King Vegeta, after getting many zenkai's. He was stronger than Nappa, who had a power level of 4,000 in the Saiyan Saga. As for how strong Bardock is in the manga (where he is called Burdock), he is stated to be in the upper ranks as far as low class warriors go. Toriyama stated this in a 2014 interview with Saikyo Jump, which you can find cited if you look at the Power section of Bardock's article on DB Wiki. Bardock is clearly weaker in the manga.

There are stronger and weaker low class Saiyans. I'd say the weakest are around 500 while the strongest are over 1,000.
