Sisseri Deo was a male Firrerreo Padawan serving the Jedi Order during the final days of the Republic Classic era. Stationed at the Coruscant Jedi Temple during the latter stages of the Clone Wars, Deo participated in the Jedi Temple Apprentice Tournament in 19 BBY.
Discovered to be Force-sensitive, Sisseri Deo was taken to the Coruscant Jedi Temple by a member of the Acquisition Division for training in the Jedi arts. At the academy there, Deo studied in a clan until he graduated from the academy and became eligible to become an apprentice to a Jedi Master.
During the Clone Wars, Deo was still stationed at the Temple and participated in the 19 BBY Jedi Temple Apprentice Tournament. Administrated by Master Ilena Xan, Deo successfully won in the first and second rounds of the competition, defeating Forzi Ghul, but was ultimately eliminated after losing to Padawan Tallisibeth Enwandung-Esterhazy.
