Unfortunately, Panaka has a less than heroic story after his role in liberating Naboo from the invasion by the Trade Federation. After the Clone Wars, Tanaka continued working for the Empire, remaining extremely loyal to Palpatine — remember, old Sheev is a Naboo native — and he even rose to the rank of Moff. The novel “Queen’s Shadow” (a great source of “Anakin sucks” information) specifies that Panaka gave his first formal address as governor of that galactic sector around the time of Padmé’s funeral.
At some point during the events of ” Leia, Princess of Alderaan,” Panaka met Leia and even deduced (or heavily suspected) that the princess of Alderaan was Padmé’s daughter. Before he could even think about divulging that information to the Emperor, however, he was killed in an attack by Saw Guerrera’s forces.
Though Panaka did not return for the other two films in the prequel trilogy, “Attack of the Clones” introduced his nephew, Gregar Typho. Typho served as Padmé’s bodyguard and, after her death, became convinced there was a larger conspiracy and set out to hunt down her killer. Together with Padmé’s handmaiden Sabé, they faced Darth Vader and deduced he was responsible for the death of Anakin Skywalker and Padmé. Unsurprisingly, Vader prevailed, but luckily for Typho, the Sith Lord spared him.
