The Sovereign of destruction is stupid
As you can tell by the head line, I think the overgod of destruction is stupid.
I can't believe that the overgod of destruction would give up his most reliable attack (his material attack)
He makes a soul attack from the 4 divine beast blood but then uses it on a overgod that has a overgod soul protection device. Why oh god (overgod) would he handicap him self twice, when fighting against a person that he had already lost against.
Making a soul attack but not using his material attack when fighting against an opponent that has a soul protection device makes no sense.
I know that some people might say that it was only a spar but i say no to that. The overgod of destruction obviously wanted to win or why would he bet with fate
In summary, the overgod of destruction develops a soul move and uses it against fate, who he knows has protection against it. Destruction might as well told Fate how he made the technique up before they had the fight
