Future King Kai contacts Future Trunks again when Future Korin gives some Senzu Beans to Future Trunks, and he teaches Future Trunks how use the beans. When Future Trunks comes back with the Z Fighters, Future King Kai teaches him to fight in team. Future King Kai uses telepathy again when Future Trunks is on New Namek in order to teach him how use the Dragon Radar.
