No, no.. Yamamoto is the strongest shinigami born in the last 2000 years. NOT the strongest shinigami born. Shinigami have assumedly been around much longer than that and so has the Soul King. I am also assuming, that Zero Squad has generations, and Ichibei is to it somewhat like Yamamoto is to the Gotei 13, one never replaced or the like.
