Thanos is a variant of Thanatos, while Thanatos was originally a god related to death in Greek mythology.
In 2008 ~ 2009, a subtitle translation team translated it as "world overlord" or "Thanos" for short, in order to highlight its domineering. There is no such name as Thanos in Hong Kong and Taiwan.
Thanos's original name, his original name is Dione. In cartoons, Thanos once saw himself in the future and mentioned his name when he recalled his memory. Later, in order to highlight the domineering, the name was changed to Thank OS, and the subtitle translation team pushed its domineering to the peak.
10 years later, Thanos has become an official title, and Thanos directly translated into Thanos in Avengers 3: Infinite War.
