One of the things that Dragon Ball Super did well was give more priority and relevance to several characters ignored in Dragon Ball Z
Dragon Ball, like the rest of the titles in the manga/anime industry, is not a perfect work. And, just as he has done very good things that have allowed him to earn his status, he has also made some questionable decisions, one of the most criticized being the excessive attention that the Saiyans have hadleaving many other characters in the background.
Even though there is a character who has been treated in the worst way in the franchise, There are also many others that were not the most relevant during Dragon Ball Z or they were seen very little, but that, fortunately, Dragon Ball Super has corrected by giving them more prominence.
Master Roshi
Master Roshi had a great opportunity to shine in Dragon Ball Super
Master Roshi was one of the first characters that was introduced in the franchise and was relevant in the original series. However, during Dragon Ball Z, he was relegated to a more comical role as a pervert and made people laugh with the beatings he received for his actions. And this was a mistake, since he has always been a strong character. Fortunately, in Dragon Ball Super he had his time to shine.
It all happened during the events of the Tournament of Power. And if we go to the Dragon Ball Super manga, we can see that it has more participation. In fact, he even went so far as to confront Jiren, demonstrating his hundreds of years of combat experience. This was a breath of fresh air and something positive for the character.
Android 17
Android 17's participation in Dragon Ball Z was minimal, since he was limited to being an antagonist at the beginning of the Cell arc and after this villain absorbed him, we didn't hear anything more about him. However, Dragon Ball Super shows us more about this character, as it is revealed that he got married and that He is dedicated to taking care of nature on an island as a forest ranger.
Goku recruited this Android to join his team in the Tournament of Power. And definitely 17 was one of those that had the best performance. In fact, he was the main protagonist of this event and was the one who won the victory, working as a team with Goku and Frieza.
Kaio-Shin
Shin also gained importance when his life bond was revealed.
Shin was a character that was introduced at the beginning of the Buu arc in Dragon Ball Z. This is the Supreme Kai of the East in Universe 7. At first, he was someone who looked powerful, but later his role fell into the background as a simple support. However, Dragon Ball Super offers us more information about his role that gives him more depth.
One of the most shocking revelations in Dragon Ball Super was the fact that Shin and Beerus, the God of Destruction, they share a life bond; That is, if one dies, the other too. This makes Shin's life and integrity more important. Not to mention that he is also extremely useful with his knowledge of the multiverse.
Bardock
Although Bardock and his movie do not belong to canon, this was changed in Dragon Ball Super, where its official presentation was made in the plot. But this series, in the manga, did something very well, as it gave depth and development to this beloved character.
When Vegeta and Goku hear Bardock's story on the planet of Granolah and subsequently see the message he left on his Explorer device, they understand more about his nature as a Saiyan, accepting and embracing his roots, but without bearing the sins of his race. This information was fundamental for the growth of these characters, not to mention that it also greatly improved Bardock as a bloody Saiyan, but who treasured his family.
