He first appears in the "King of the Snake Men" MOTU minicomic, where he and Tung Lashor are called from another dimension by King Hiss. When they appear, Kobra Khan says they "are from the Evil Horde on Etheria!", but both Snake Men swear allegiance again to their former leader King Hiss.
He also appears in the She-Ra: Princess of Power TV series as a member of the Evil Horde and, in later episodes, one of Skeletor's Evil Warriors. The original MOTU cartoon had come to a close by the time his figure was released.
2002 SeriesHe also appears in the 2002 series, where he is not only one of the Snake Men, but now the general of King Hiss's troops. In the episode "Snake Pit", General Rattlor is the first Snake Man freed by Kobra Khan. While formerly portrayed as another henchmen in the Filmation series, the Rattlor of the new series is a commanding figure and a cunning tactician who serves as King Hiss's right-hand man. He also gradually develops a rivalry with Kobra Khan who attempts to replace him as King Hiss's lieutenant. This version of Rattlor often makes allusions to his, and the other Snake Men's taste for human flesh, something that was deemed too controversial for the Filmation series.
