During Interplanetary Preps, head to Master Roshi’s house to find Krillin, who will have this substory for you. He has figured out a way to train while travelling to Namek, which involves using your mind. While trying to picture Krillin in your mind, you end up forming an image of Nappa, so you will have to fight him. This form of Nappa is pretty easy, as he doesn’t seem to have access to all of his Super Attacks. Once you defeat him, you will have to do battle once more, this time against Krillin. As with all other fights against Krillin thus far, all he seems to have is the Kamehameha, so he will go down pretty quickly, bringing an end to this substory.
