This new Power Ranger's design is an amalgamation of Tommy Oliver's Green Ranger and White Ranger costumes, and this is done on purpose as this new Ranger has a deep connection with Tommy Oliver. How he is connected with Tommy will be revealed in later issues, to be specific, we will meet his alter ego on issue #11, and his origin story on issue #12. The original plan was to feature the White Ranger, but it later evolved by incorporating elements of the Green Ranger.
The new Ranger was designed by series cover artist Jamal Campbell in collaboration with series writer Kyle Higgins and Saban Entertainment, making this the first new Ranger in the Mighty Morphin Era.
