This team is composed of the Ranger Slayer, Magna Defender, Zeo Ranger II Yellow, Green Samurai Ranger, Red Space Ranger, and the mysterious Dark Ranger (formerly known as Dino Charge's Talon Ranger). This is the first time the Dark Ranger made his appearance in the Power Rangers series outside of toys. As to the reason why this team was formed, more details will be revealed in the Shattered Grid crossover's finale issue. This will be the team in the Mighty Morphin Power Rangers comic book, at least in the foreseeable future.
Bennett, who is a fan of the Power Rangers growing up stated that it is a dream come true to write the series. She hopes to keep the momentum, vigor, and emotion of everything the previous team has set up into a new world of possibilities.
