en PortalulTauTV. By the power of Grayskull... In November 2015, "Masters of the Musical Universe" debuted at the Headwaters Theatre for a brief one-weekend run. With a small cast of eight, John-Ryan Griggs and Meghan Trause paid tribute to their beloved cartoon characters with this witty satire based on the original "He-Man and the Masters of the Universe" and "She-Ra: Princess of Power" cartoons. The show was called "electric" by Simon Springer of HeManWorld.com, and delighted fans for its four sold-out performances.
