In early drafts of <I sizset="80" sizcache="2">Attack of the Clones</I>, the name of the Jedi who contacted the Kaminoans was Sido-Dyas, pointing to a likely early conceptual connection to Darth Sidious. However, interestingly, "Sifo-Dyas" appears in one place, apparently as a typing mistake (as the D and F letters are located next to each other on a QWERTY keyboard) that Lucas later preferred to the original name.<SUP class=reference id=cite_ref-draft_0-0 sizset="82" sizcache="2">[1]</SUP>

In addition, "Sido-Dyas" was originally only a false identity for Sidious—Obi-Wan claimed never to have heard of him, and Mace Windu confirmed that there was no Jedi by that name.<SUP class=reference id=cite_ref-draft_0-1 sizset="83" sizcache="2">[1]</SUP>

His backstory was promised by George Lucas to be revealed in <I sizset="85" sizcache="2">Revenge of the Sith</I>,<SUP class=reference id=cite_ref-1 sizset="86" sizcache="2">[2]</SUP> but instead is now explained in the lead-in novel, <I sizset="87" sizcache="2">Labyrinth of Evil</I>.

The first visual appearance of Sifo-Dyas was in The Eyes of Revolution comic featured in Star Wars: Visionaries. The story was written and drawn by ILM concept artist Warren Fu and as a little easter egg, or inside joke, Fu used himself for the face of the Jedi Master. Artist Chris Trevas noticed Fu\'s likeness in the comic while doing research for his own illustration of Sifo-Dyas in <I>Jedi vs. Sith: The Essential Guide to the Force</I>. For the sake of continuity, and respect for a fellow artist, Trevas contacted Warren Fu to reprise his role for the Jedi vs. Sith illustration as well.<SUP class=reference id=cite_ref-2 sizset="91" sizcache="2">[3]</SUP>

His name was changed to "Zaifo-Vias" in Brazil, in order to avoid puns on his name. (Sifo-Dyas sounds like "Se Fodias", which means something almost like "we\'re having sex" in a formal 2nd person.)

요약)
1) 클론의 습격 초안에는,사이포 디아스는 존재하지도 않았습니다. 원래의 이름은 사이도 디아스(Sido-Dyas) 였다고 하네요.
이 이름은, 사이도 디아스는 시디우스와 비슷하게 들리기 때문에, 클론을 주문한 사람이 결국 다스 시디우스였다 라는 복선을 심어주기 위함이었다고 하네요. 그런데, 초안 작성중 그것을 옮기던 사람이 sido-dyas의 d를 너무 바쁘게 쓴 나머지 f로 써버려서(QWERTY 키보드에서 f는 d옆에 있음)
사이포 디아스가 되어버린 거지요.

2) \'The Eyes of Revolution\' 에 나오는 사이포 디아스의 얼굴은, 작가 Warren Fu의 얼굴을 기반으로 만들어졌답니다.

3)사이포 디아스의 이름은 브라질에선 \'Zaifo Vias\'로 바뀌었다는데요. 사이포 디아스는 \'세 포디아스\'로 들리는데,
  브라질 말로 \'우리는 섹스하고 있어요\'라는 뜻이기 때문이랍니다.
