Planet Genesis is the planet where the famed Senzu Beans come from. It is located in another dimension, accessed by Korin when he was a wandering cat. Korin, after interacting with Regenesis, came back with the Senzu Beans in tow. Regenesis has not met Korin since. Even back then, Korin perceived Regenesis to be a greater threat than even Cell, and that was the first time he had met creatures of that level of power.
