Siro Altman and beria Altman appear in the plot at the same time. From the beginning of their debut, they seemed to be intertwined and inseparable from each other. I have to say that these two Otto warriors are super strong, and they have the ability to directly destroy the country of light as soon as they appear. In view of what kind of relationship exists between them, we can actually talk about it from multiple angles, so I will briefly talk about it.

There is an old enemy relationship between Siro Altman and beria, which is very common in the plot, because most of Otto's fighters and villains have this relationship. Besides Siro and beria, Otto's father and beria are also old enemies. The old enemy relationship is the old enemy relationship, and some old enemy relationships can even last forever. Old enemies like Ciro and beria can last forever, because beria was defeated by Ciro in previous appearances, which has become a fetter in his heart, and he tried his best to kill Ciro.

In fact, there is a close interpersonal relationship between Ciro and beria. Beria was once an Otto warrior in the land of light. If he hadn't become the evil Altman, he would still be in the country of light and a more senior Otto warrior. He has the same qualifications as Otto's father. That is to say, if beria is still an Otto warrior in the country of light, then Ciro will call beria Grandpa. This is their relationship.

There are only two relationships between them, and the second relationship about him is not shown. Only according to their seniority, they are really grandchildren, because his father Sai Wen is the adopted son of Otto's father, and Otto's father is the same as beria's father.
