He is currently the head of Liberty and Discovery Automatic Corp and secretly controls the September Institute and the Lux Vox Data Research Center (he refers to this shadowy affiliation as the Righteous Vanguard because of course he would call it that.)
According to Austin Ibex has the potential to be the best kisser in the Golden Branch, but because he wants to be #1 so bad he will only ever be #2.
He is a real fucker.
Prior to becoming a Candidate, his name was Attar Rose; he worked with Maryland September, helping her found the September Institute. His younger brother Quentin later became Detachment's Candidate, Jerboa.
At some point after the Golden War, he gained several robot clone bodies that all had Righteousness installed on them (because of course he did).
After the September Incident, he gave his Candidacy and position as the leader of the Righteous Vanguard to Aria Joie and mysteriously disappeared. He came out of the shadows as the final fight with Rigour approached, but was killed by a Rigour-enthralled clone of Maryland September.
