Keanu, who could not win a single battle, went with Nincada to a cave on Dewford Island, where Nincada used Secret Power to make the Secret Base. Though Keanu decorated the room, he felt he was even disappointing Nincada by not battling.
Seeing the heroes entered his Secret Base, Keanu had Nincada attack them with Fury Swipes, forcing their way out. However, Team Rocket arrived and stole Keanu's Nincada, then forced it to dig to transform the Secret Base. Though Team Rocket were forced out by Team Magma, they managed to sneak in, seeing Team Magma and Aqua members arguing with each other. Once the trouble settled down, the heroes helped Keanu retake Nincada, who used Secret Power to blast Team Rocket away. Despite his old base destroyed, Keanu promised to build a new one with Nincada, as well as to train it for battles.
