The Power Rangers franchise celebrated its 20th anniversary in 2013.
The anniversary marked two decades since Mighty Morphin Power Rangers first premiered in 1993. Saban Brands promoted 2013 as a major celebration, pairing anniversary events and merchandise with the launch of Power Rangers Megaforce. Megaforce was the franchise's 20th television installment and featured story elements designed to honor earlier Ranger teams.
The celebration is sometimes associated with Power Rangers Super Megaforce, which premiered in 2014. Super Megaforce was the follow-up season and expanded the anniversary concept through Legendary Ranger powers, allowing the new team to assume forms inspired by Rangers from earlier series. Its timing can make 2014 seem like the anniversary year, but the official 20th-anniversary campaign centered on 2013.
The other options represent nearby dates rather than the correct milestone. 2012 preceded the anniversary, 2014 was the year Super Megaforce aired, and 2015 followed the twentieth year. The franchise later marked its 25th anniversary in 2018 and its 30th anniversary in 2023.
