Alk'iod'inrokini is a Chiss agent in the Eclectic Subdivision of Advanced Species division of the Department of Floaters. She is known by her core name "Iodin" within HQ because most non-Chiss find pronouncing her full name (in the Chiss language, Cheunh) very difficult if not impossible. Like all Chiss, Iodin has blue skin, blue-black hair and glowing red eyes. When on missions in sci-fi continua, she uses a charric (a combined particle and energy weapon native to Chiss space).
