1983 Mattel MOTU/POP Mini-Comic Canon:
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.
1984 World MOTU/POP Annual Books Canon:
In this canon, Rattlor is Tung Lashor's best friend, although what the two find to talk about is a mystery, as Rattlor prefers hissing to speaking. This silence gives him a mysterious, eerie quality, which he uses to great effect in combat. Just before he strikes, he will sound his battle rattle, giving his victim a tiny traction at a second to realize their horrible fate.
1985 Filmation MOTU/POP Animated Series Canon:

2002 MYP MOTU Animated Series Canon:
Rattlor was 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 idiotic henchmen of the Evil Horde in the Filmation animated series, the Rattlor of the new series is a commanding figure and a cunning tactician, who serves as King Hiss's right-handman.
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 animated series.
