Zachery was the most powerful pirate because there were no other pirates who could defeat the three factions’ alliance and challenge the Confederation publicly.
He made the first contact with the Kaedians and brought the scourge of war to earth.
The Pirate King Zachery was one of the brightest stars in the history of interstellar pirating history. He could have made history if he had not been confronted by the most powerful man in the world—The Blade Warrior.
During that time, Zachery was the only person whose power could rival Li Feng and Rilangalos.
However, all that he had built up had been destroyed by Li Feng. Wang Tong reckoned that Einherjar Wannabe was a much more terrible opponent than even an Einherjar because of his brutality.
Wang Tong conceded that he could not let such a maniac let loose in the real world, so he decided that he should do whatever it took to keep Mr. Wannabe in here.
