Dooku is Syfo-Dyas. Jango Fett was hired by Dooku to have his DNA create a clone army. Now, either Dooku or a bounty hunter killed off Syfo-Dyas so they could use his name. Dooku used to be a Jedi, so he (being a Jedi) could have erased the systems. Sorry, this time I think someone has three identities.
