Silva waited for them to make the first move. He had a mind focused on each one of them, and the rest of his mind for processing the fight.
He might have more power than all of them, but they were all variants of him that had access to systems as well, or had access. They would definitely possess an arsenal of unique skills that he hadn't seen before.
So even as a demigod, he had to keep his senses sharp as he fought. But as he watched them, they also watched him. No one moved, turning the situation into a stalemate before they started.
Then all of a sudden, a middle-aged variant moved. Black lightning blazed all over his body and he was gone in a flash.
Silva had not seen anyone with that amount of speed before. He tried to follow with his eyes, but even that was hard for him.
Luckily, he was able to predict where the attack would come from at the last moment. It was the benefit of several powerful minds.
