The Masters of the Universe Classics line that started in 2008 greatly elaborated on the history of Anwat Gar and it's people, the Gar. It was revealed that all blue-skinned characters from Motu productions, such as Keldor/Skeletor, Sy-Klone and Shokoti, are members of the Gar species.
Anwat Gar was a wordplay on Angkor Wat, a temple in Cambodia, which has become a symbol of the country, appearing on it's national flag.
The "Legacy Armor" granted to He-Man and Skeletor by the Legacy Stones is based on the "Samurai He-Man" and "Samurai Skeletor" action figures respectively, released in 2003 by Mattel.
