Beerus is introduced as one of the 12 Gods of Destruction in the universe of Dragon Ball Super. Among the numerous deities in Universe 7, Beerus is the most powerful God of Destruction. As the deity responsible for maintaining balance in the universe, he is tasked with the duty of ensuring cosmic order.
Beerus made his first appearance in the movie Dragon Ball Z: Battle of Gods. Despite his immense power, this deity is characterized by his laid-back and humorous demeanor, often displaying a rather relaxed attitude.

During his first journey to the Earth-like planet, Beerus unexpectedly encountered Majin Buu while seeking delicious food. This incident nearly led to the destruction of the Earth, but fortunately, it turned out to be a minor issue.
Since then, Beerus has maintained a friendly relationship with some Earthlings. However, the unpredictable and volatile nature of the God of Destruction makes it uncertain whether he will remain the same in the future.
Recent developments in the Dragon Ball Super manga and movie suggest that Beerus will engage more in training Goku, Vegeta, and Broly. There is still uncertainty about when or if he will return as the God of Destruction for Earth.

After training Goku and Vegeta to become formidable warriors, Beerus expressed a desire for a battle where he could unleash the full extent of his might if need be.
Nevertheless, Beerus remains a character of great complexity. He is neither entirely good nor entirely evil, and there is a possibility that he could evolve into a new God of Destruction in the future if the Z fighters do not exercise caution. His unpredictable nature makes Beerus a captivating character, leaving fans of Dragon Ball Super genuinely concerned about what may transpire in the near future.
