Apollo is a unique individual in that he/she/it is not an individual at all, but five separate teenagers who form a new entity. Strom, Meda, Quant, Manuel, and Moira are a pod, as these kinds of personalities are called, genetically engineered to work as one and to be able to communicate non-verbally. As a rare quintet, much relies on the successful training of Apollo, but as more accidents occur, the pod members struggle just to survive.
