Jonus was a captain in the Imperial Navy who often flew as the top cover during bombing runs. At one point, he served under Gamma Squadron. He eventually served with Death Squadron under the bomber squadron Scimitar at the time of the Battle of Hoth. He narrowly escaped being eaten by a space slug once when he had to evac. He scored several kills against numerous Rebel blockade runners during his early years with the Imperial service. He was last seen evacuating Death Star II during its explosion, but it isn't known if he escaped.
