Thanks to RangerCrew user, @monapromaray and the airings/spoilers in India it has been revealed today that Dino Super Charge will end in a three part finale!
This is the first time Power Rangers has gotten a three part finale since 2001 with Time Force!
[EDIT: it may be that the 3 part finale may be a 3 part arc ala Jungle Fury’s Finale arc.]
The Finale will begin & conclude with Episode 18, 19 & 20. Still no word yet on the Official Return of the series.
Here is a brief synopsis of Episode 18:
“An evil monster attacks the Rangers, turning some of them to stone. Shelby must work with Keeper to create a new Zord, the only plan that can save her friends.”
