Jonas Wallen was a Human male senator who represented the Eucer sector to the Galactic Senate during the Separatist Crisis. Around 22 BBY, he was involved in a gambling scandal with fellow senator Char Bibbeck, in which the two senators were accused of betting on which planets would secede from the Galactic Republic. Jonas wanted to continue his scandal, but Char refused to waste credits since he believed it was futile. He was later assassinated by Aurra Sing who was hired by the Confederacy of Independent Systems in order for both sectors to join the Separatists.
