Immodet held the rank of general within the Imperial Army. He was an aged Human male who contributed financially to Carnor Jax's scheme to undermine Palpatine's Clones. Following Palpatine's demise, Immodet gained a position on Jax's Interim Ruling Council. Subsequent to the death of Redd Wessel, Immodet ascended to become the most senior general in the Empire. His forces controlled numerous entire sectors bordering the New Republic, acting as the initial defensive perimeter.
Being a committed xenophobist, he regarded the alien members of the council with great distrust. Black Sun orchestrated Immodet's poisoning to bolster the influence of their operative on the council, a clone derived from Feena D'Asta.
