Akira Toriyama's Dragon Ball Super is an incredible addition to the popular Dragon Ball franchise, taking the characters on even bigger, bolder adventures. Ramping up the challenges in an action-packed universe like Dragon Ball is no small feat.
However, Dragon Ball Super succeeded, by bringing a host of powerful new characters and an expanded multiverse. Among them, the God of Destruction Beerus from Universe 7 is one of the strongest.
As the story progresses, Goku and Vegeta gain god-like powers with their Ultra Instinct and Ultimate Ego techniques. Beerus shows interest in training them to become the new gods of destruction of universe 7.
However, it seems that Goku is not interested in this role. Perhaps Beerus will have better luck considering another Saiyan: Gohan.
The transformation into Beast form is possibly Gohan's most powerful transformation, as seen in the series at this time.
Those who witnessed Gohan Beast's fight against Cell Max assured that he surpassed Goku and Vegeta in terms of strength. Vegeta, Broly, Beerus, and Whis are surprised by Gohan's new power level, suggesting that Beerus should consider Goku's son as a candidate for the position of God of Destruction.
In addition to strength, Gohan also has explosive Ki, surpassing that of Goku and Vegeta, which makes him an even better candidate for Beerus's successor. Ever since he was a child, Gohan's anger has guided him in crucial moments.
Gohan also has a deep understanding of the balance of nature, an essential trait of the God of Destruction. His work as an entomologist reflects his care and compassion for the natural world, helping him understand the necessary balance in the universe.
Seeing other gods of destruction in action, Gohan is no stranger, unlike Goku and Vegeta, who have complex relationships with the multiverse. Gohan can foster positive relationships between universes, an important aspect of Universe 7's security.
Ultimately, the fact that Gohan survived without dying in the main timeline highlights his strength, intelligence, and strategic abilities. This makes him a logical choice to be the next God of Destruction, a position he is more than capable of taking.
