Gaius Caesar
The Julio-Claudians continued to rule Rome after Augustus' death and remained in power until the death of Nero in 68 AD. Augustus' favorites for succeeding him were already dead in his senescence: his nephew Marcellus died in 23 BC, his friend and military commander Agrippa in 12 BC and his grandson Gaius Caesar in 4 AD. Influenced by his wife, Livia Drusilla, Augustus appointed her son from another marriage, Tiberius, as his heir.
