The fifth Power Morphicon was recently announced with dates for August 2016.
Power Morphicon, a Power Rangers-centric convention run by fans, began in 2007 and has been held bi-annually since its second convention in 2010. Each event has brought a number of guests from the Power Rangers alumni along with guests from shows such as V.R. Troopers, Big Bad Beetleborgs and Kamen Rider: Dragon Knight.
In 2014, Power Morphicon welcomed its first Super Sentai actor as a guest to the event, Yuuta Mochizuki who played Tyrannoranger Geki in 1992’s Kyoryu Sentai Zyuranger. He also attended a panel with the original Red Power Ranger, Austin St. John. Power Morphicon 2014 also saw the inclusion of Super Sentai stunt actors Hiroshi Maeda and Yasuhiro Takeuchi as well as the reveal of the Power Rangers Dino Charge cast.
The fifth Power Morphicon will be held on August 12th-14th at the Pasadena Convention Center in Pasadena, CA. Memberships will go on sale on August 1st, 2015.
