Watch full movie online. For the honor of Grayskull... The sequel to 2015's "Masters of the Musical Universe"; "Battle for Etheria," directed by John-Rhyan Griggs and Meghann Trause, brings new characters (and a few "buffed up" old ones) as He-Man and She-Ra fight Skeletor - and the evil Hordak - to a mix of '80s tunes. "Masters of the Musical Universe: Battle for Etheria" ran for just one weekend that jam-packed hundreds of theatre-goers into five sold-out performances at The Headwaters Theatre in September 2016.
