- The war was known to have taken place somewhere between AGE 720 and AGE 730. According to Saiyans' appearances, they were not yet members of Freeza's army. Then enters Dragon Ball Super: Broly, which tells us that Freeza not only ruled the Saiyans for "just" five years (from AGE 734 to AGE 739), King Cold was previously in charge. In that scene in which appears an image of Freeza and King Cold behind Bardock, the latter says that King Cold appeared and started to rule them, to which Leek replies that "it was a long time ago".
Now, "a long time ago" would definitely change when the war takes place, specially if we take into consideration the information that a moon only appears in planet Plant once every eight years (though that's a tidbit which would most likely be ignored if Toriyama would ever show his version).
- So, as implied by the guidebooks, King Vegeta is the first king of the Saiyans. He got the title by "merit" after leading the Saiyans to war. Then enters Dragon Ball Super: Broly, which tells us he is actually the third. That not only tells us that King Vegeta may not have led the Saiyans against Tsufurujins, the monarchy may have been established before the war (or even before Saiyans traveled to planet Planet).
- In the OVA, Vegeta says that Tarble was sent to another planet by their father due to his lack of talent for battle. In Dragon Ball Super: Broly, Vegeta does not know what happens to him.
If that scene had happened before the destruction of planet Vegeta (as it is the case in Dragon Ball Minus), we could assume that King Vegeta told Vegeta what had happened to his brother (and that is assuming King Vegeta died not by facing Freeza, but he was sitting on his throne or doing anything else when the planet was destroyed). But according Dragon Ball Super: Broly, that scene takes place after the destruction of planet Vegeta and King Vegeta was certainly dead by that time. How does Vegeta gets to know what happened to Tarble once the latter goes to Earth? We'll never know.
Anyway, what do you think of all this? Should Toriyama or anyone else depict one definite version of all these stuff (with chances of more things being altered) or let it be convoluted as is?
