On Jan. 15, he returns to New Zealand to shoot the second half of the Ninja Steel story arc through May. That will be the show’s 25th anniversary, airing in 2018 with guest appearances of the most popular past Rangers, Shewfelt said.
In terms of non-ranger alumni, we’ve already seen Kelson Henderson who has played various roles on Power Rangers including Boom from Power Rangers SPD, but footage from the sentai counterpart Ninninger does lend itself for past rangers to appear: Yellow Ranger from Magiranger, Red Ranger from Kakuranger, and both Red and Green Rangers from Hurricaneger. (Power Rangers Mystic Force, Mighty Morphin’ Alien Rangers, and Power Rangers Ninja Storm respectively.)
But are these the “most popular” rangers or are we in store for more surprises? Power Rangers Ninja Steel premieres Saturday, January 21, 2017 on Nickelodeon.
