While Dragon Ball’s main narrative isn’t particularly convoluted, several incomplete story lines have been referenced along the way. Most haven’t been expanded upon more than when they were briefly mentioned, and as the years go on, we’ve begun to think that we’ll just be left in the dark when it comes to a few of these stories.
Vegeta’s brother Tarble
Although the Dragon Ball Z OVA entitled Yo! Son Goku and His Friends Return!! may not be canon, Vegeta’s younger brother Tarble definitely is. Even if fans haven’t seen the OVA, it’s clear that Tarble isn’t as strong as his older brother, but we can’t help but wonder just what he was doing when he got the news of Planet Vegeta’s destruction.
We know that Toriyama won’t give us the privilege of exploring this Saiyan’s story, but we know it would make for a very interesting story. Plus, we’d be able to see some of his techniques in action in his battles.
Goku’s Experiences On Planet Yardrat
Even though we’ve seen a Yardrat in action during the Tournament of Power, Goku’s specific experiences on Planet Yardrat have never been illustrated in the series.
It would be amazing to see Goku struggle to learn Instant Transmission, or even see him devouring pounds of whatever they serve on Planet Yardrat.
How Frieza Assembled A New Frieza Force
Frieza had been dead for years, but upon his first resurrection, he still had loyal supporters like Sorbet, who kept the remains of his army intact. After the Z-Fighters incapacitated this fighting force, he not only destroyed them by powering up, but even Sorbet met his end, reducing Frieza’s numbers to zero. So how was he able to assemble such a massive force in Dragon Ball Super: Broly?
Sure, his name carries weight throughout Universe 7, but even Rome wasn’t built in a day. He even managed to get a kind-hearted soul like Cheelai to join his new army, leaving us to wonder just what kinds of benefits Frieza had been offering to recruit these new members.
Goku’s Experiences During The 7 Years He Was Dead
After being dead for seven years, we can confidently say that Goku didn’t run out of things to do in the Other World. We know for a fact that during this time, he discovered his Super Saiyan 3 transformation, trained with fighters from all corners of the Universe 7, and even picked up the Fusion Dance from the Metamorans.
He could’ve even hung out with his dead family members, Grandpa Gohan included, but Toriyama’s never felt the need to expand on the years he spent as a dead man, and honestly, he doesn’t need to. The story moves along just fine without it! Still, we’d be lying if we said that 7 years wasn’t a long time. Seeing what Goku did in the Otherworld could only add 7 years back onto our own lives.
Trunks And Mai In An Alternate Universe
After Future Zeno erased Future Universe 7, Future Trunks and Future Mai found themselves with nowhere left to go.
After Whis agreed to go to a time where Universe 7 still existed so that he could warn Future Beerus to destroy Zamasu, the two would be allowed to live in this alternate future universe, but the caveat was that a Trunks and Mai would already be living there.
