I was wondering why Count Doukou didn't have a Sith with Darth like all the other Sith Lords. My sis says it's becuase he wasn't fully trained. But Anakin wasn't a fully trained Sith Lord and he got his name,but why not Doukou?

It's like Obi-Wan said, his sith name was Darth Tyrannus. They called him Dount Dooku because he was the son of a count on his halaman awal planet of Serenno. After he left the jedi, he went back to Serenno and took over his father's estate as count. When he became involved with Sideous and the Seperatists, he called himself Count Dooku still, prpbabaly partially because he may have wanted to hide his identity as a sith from the jedi and probably partially because he wanted power. So yes, he did have a sith name: Darth Tyrannus.

Count Doukou was never intended to become a
Sith Lord. He was a member of the Sepratists and in alliance with them. The Sepratists have red light sabors as well as the Sith. And they also have no mercy for the Jedi. That is why they are against them. But in a match they would lose against the Sith as well because they are not in alliance with them completely. Ventress, Vice Roy Gunray, General Greivous are all Sepratists.

Hes Sith name is Darth Tyranus,but why do they call him Cont Dooku i dont know
