Prince Zed is a minor character from the 1985 animated series She-Ra: Princess of Power.
She-Ra: Princess of Power
Prince Zed is the son of Horde Prime, who addresses Hordak as 'uncle'. This could suggest that Prime is Hordak's brother, but it is also possible that Zed only called him 'uncle' as a friendly term, or he is on Zed's mother's side. However a letter from this episode said "your nephew" stating that Hordak is his uncle but we don't know on which side. How Prince Zed is Horde Prime's son still remains to be seen.
At first, Prince Zed is a spoiled brat, but during a battle, he is captured by the Great Rebellion, but they tend his injuries rather than lock him up. When he sees the consequences of Hordak's latest plan of poisoning the Whispering Woods he has a change of heart. Hordak, fearing Horde Prime's wrath, accepts Prince Zed's deal to return with him in exchange of undo the poisoning, but Hordak doesn't intend to fulfill his part of the deal and is only stopped by the fact that Madame Razz added an antidote to his poisonus formula. Zed returns with the Horde, assuring his new friends that on the day he takes his father's throne, he will release Etheria, and all other worlds, from Horde control.
