As you CBMers may or may not know, The 21st season(and possibly the 20th too!) of Power Rangers, Power Rangers Super Megaforce, will be slightly loaded with cameos from past season rangers such as Jason David Frank and more! Here is the glorious piece of evidence of 6 returning rangers
As you can see in this shot, The returning cast will be Hector David Jr. as Samurai Green, Brittany Pirtle as Samurai Yellow, Jason David Frank as the legendary MMPR Green Ranger, Patricia Ja Lee as Space Pink, Selwyn Ward as Space Blue and Danny Slavin as Galaxy Red. Also, if you look closely you can see stunt actors in other past season ranger suits.
According to this promo poster, JDF himself may be getting his own Megaforce episode similar to what Jason Smith, Jungle Fury Red, Will be getting.
