Here is an interesting excerpt from Bob Forward's script for the season one She-Ra episode "Horde Prime Takes A Holiday". Earlier in the script Bob mentions that Horde Prime should not be seen; which makes sense to us, as his actual look was never revealed during the series. However, at the end of the episode the script states that upon Horde Prime's return he should be seen "decked out in dark tan, Bermuda shorts, and a wild Hawaiian-print shirt". I will be the first to express my confusion, and my gratitude that we never saw that particular scene come to life!
