In 2018, Boom! Studios made a graphic novel as a tribute to the late JDF aka. Tommy Oliver. It tells the story of his final moments as a Power Ranger, and how his son J.J. became one in his father’s honor. It also features Lina Song, who is currently SPD Blue, Sky, who is now promoted as the Deka Ranger, and Bridge the Red Ranger with a Fire Squad vest since Once a Ranger.

Many fans wonder about the events after that novel story. Maybe J.J. will earn his own Battlizer. Maybe Grumm and the A-Squad will escape to get revenge. Maybe Jack will return to assist his allies. All will be revealed once Hasbro makes a sequel or an animated series based on Soul of the Dragon.
