Reused animation: the opening shot and subsequent direction is based on animation from Into Etheria (1985), the scene where She-Ra and He-Man destroy the guard tower uses animation from The Price of Power (1985), and Bow and Glimmer drive a Horde transport vehicle away using animation from The Peril of Whispering Woods (1985).
The sequence of He-Man and She-Ra working together to lift and throw a large object was first seen in He Ain't Heavy (1985) and would be seen again in Sweet Bee's Home (1986).
