However, the two stop in response to the Action Commander Zodomas, whose swordsmanship attracts Joe's attention and fights him as the Gokaigers battle the Gormin. However, the Action Commander overpowers Gokai Blue and takes his leave as the other Gokaigers arrive. While the others eat, Joe proceeds to hone his fighting style to counter Zodomas's fighting style with Ahim forced to watch before Joe tells her. As Luka tells Ahim to accept his reasons out of friendship, Joe completes his training. The next day, Joe finds Ahim waiting for him and as she gives him her Gokai Saber to use in his upcoming duel with Zodomas. However, Zodomas uses Sugormin to as Gokai Pink arrives to his aid before the other Gokaigers arrive. After the others assume the forms of the Gekirangers and Dekarangers to take out the Sugormin, they give their GokaiSabers so GokaiBlue he can use a five-blade fighting style to defeat with his Five-Blade Style Blue Slash. When Zodomas and the Sugormin are enlarged, the Gokaigers form Magi Gokaioh to ground Zodomas before destroying him. Soon after, Joe presents a "thank you" cake to the crew and is modest about it.
