Палпатин - НЕ КОС!

[гросс-адмирал Траун]

Его имя "приклеили фэны":
Palpatine's full name (assuming he has any names other than "Palpatine" alone) has never been revealed. The usage "Emperor Palpatine" suggests that Palpatine is in fact his only name, though the use of titles such as "Senator Palpatine" suggests it may be his family name. Of course, Palpatine might be a name of state, as the name Amidala is, so it may mean that neither Palpatine's given nor family name is known.

Nevertheless, the original version of his character in Lucas's early scripts was named "Cos Dashit" and many Star Wars fan fiction writers have quite incorrectly adopted the name "Cos Palpatine" in their stories and web pages -- so much so that it has become fanon. The name "Dantius Palpatine" has also been adopted, though its origins are more ambiguous, seeming to come from SuperShadow, a website of bogus Star Wars material, including synopses for Episodes VII - IX. On the offical website it is stated that Palpatine's first name, if he has one, has not yet been revealed.
