Hordak is his uncle but we don't know on which side. It has not yet been confirmed whether or not Filmation's writers conceived Prime as Hordak's brother. However, he is referred to as such in the Character Profiles in Disc 6 of the She-Ra Season One DVD set. Two UK She-Ra annuals in the mid-1980s state that Hordak is Prime's brother, but these operate within a canon independent of the cartoon and also altered Horde Prime's name, referring to him as 'Prime Horde'. The UK He-Man comics state explicitly in one issue that Horde Prime is not Hordak's brother, but again these operate within an independent canon, and Prime is depicted with a completely different appearance from the cartoon. She-Ra and the Princesses of Power (2018–2020) In the Netflix/DreamWorks reboot, She-Ra and the Princesses of Power, Hordak is one of the many clones of Horde Prime, who cloned himself to build a vast army to conquer everything in his path. Hordak served as Horde Prime's top general until he was revealed to be defective, and was cast out by Horde Prime, as a result, sent to die on the front lines, only for a portal to open and transport him to the planet Etheria in the empty dimension of Despondos. Horde Prime is also shown to frequently call Hordak his "little brother" despite him being abusive and considering Hordak as a wayward extension of himself. Masters of the Universe Classics In 2008, Mattel debuted the Masters of the Universe Classics (MOTUC) line of action figures. This line was to be sold exclusively on its collector-centered website, mattycollector.com. This line features classic MOTU characters sculpted in an updated style with added articulation by renowned toy sculptors The Four Horsemen. Currently, the MOTUC line has no comprehensive backstory, but the figures' packaging does include short character bios that merge elements from various incarnations of the franchise, as well as some newly developed information to form a new, distinct MOTUC continuity. Hordak's MOTUC bio states that his birth name is Hec-Tor Kur, second-born heir to the Horde Empire, who came to Eternia while battling He-Ro. Hec-Tor adopted the name "Hordak" and eventually raised an army to battle against the Snake Men for rule over Eternia. Eventually, Hordak's army defeated the Snake Men, but it was then defeated by King Grayskull, who banished Hordak to the dimension of Despondos. The official product description also
