Dragon Ball: The Super Kaioshin is very weak, so why can he still become a god?

In "Dragon Ball", not only the earth, but also "gods" exist on other intelligent planets, and the gods on these planets are their bosses, the kings of the southeast, northwest and northwest. And these Kaio-Kings are all subordinates of Kaio-Kami. Both Kaiowen and Kaioshin come from Kaixin Star, and they are Kaixin Star people. The seventh universe where Sun Wukong lives originally had five Kaiōshin, namely: East, South, West, North, and the Great Kaiōshin! Five million years ago, in a battle with the demons, the Northern Kaiojin and the Four Kaiojins were killed, while the Southern Kaiojin and the Great Kaiojin were absorbed. As a result of absorbing the Daikaiōshin, the Fat Demon was born. Buu's gluttonous nature comes from absorbing the Southern Kaiojin. In the end, only Higashikami survived. Kaioshins seem to be very weak, so how did they become gods? In fact, their strength is not weak at all

Kaioshin has the ability to crush Frieza back then. According to his own introduction, he can kill him with one finger. At the beginning of Buu's chapter, Piccolo's attitude towards Kaiowen God at the martial arts conference explained everything. Although there was Wia from the superior, this warrior who had been trained by Frieza and Hiru had no idea when he saw Kaiowen God. It was immediately clear that the strength of both sides was not in the same dimension. Since Piccolo can come to participate in the martial arts tournament, it shows that he has the confidence to fight against the Super 2 Saiyans, but he is instantly intimidated when facing Kaioshin. Indirectly, it also shows that Kaiohshen at this time is as powerful as Goku and others. The main function of the Kaio God is not to fight

As opposed to the God of Destruction, the Kaio God is the god of creation and will only intervene in major events related to the fate of the world. The responsibility of Kaiowashin is to create the planet and create "keys" to allow life on the planet to flourish and develop. As an attendant of Kaioshin, he has many abilities that even Kaioshin does not have, such as the ability to heal. In the Buu chapter, Jaibit, the attendant of Kaioshin, healed Son Gohan. There is also teleportation, an ability that can only be used by Goku, Gebit, and East Kaiojin. Eastern Kaioshin didn't know how to do it at first, but he learned it while he was merging with Gebit!

The strongest of the Kaioshins is Zamasu. Zamasu once served as a Kaioh, and later became a trainee Kaioshin. After merging with Goku Black, Zamasu defeated Goku and others. In the end, it was all King who used "Erasure" that destroyed Zamasu and Mirai together.
