Over the years the Power Rangers have gone from being the original Mighty Morphin version through Alien, Zeo, Turbo, Space, Lost Galaxy, Lightspeed Turbo, Time Force, Wild Force, Ninja Storm, Dino Thunder, S.P.D., Mystic Force (my favourite - Wil), Operation Overdrive, Jungle Fury, RPM, Samurai, Super Samurai, Megaforce and ending up today in the 2014 line-up of Power Rangers Super Megaforce.
The new season starts in February and Nickelodeon has released a trailer, which is below.
You can watch Power Rangers on Nickelodeon and Channel 5.
