Stereotomy (ステレオトミー Sutereotomī?) is a process created by Desty Nova to regenerate himself after his death. As a result of other circumstances, this resulted in multiple incarnations of him existing simultaneously. A variation, Stereotomy D (ステレオトミー D Sutereotomī D?), was created by Nova X to produce the Nova Decoys, dumbed down versions of Nova that distracted the Tipharean survivors and enabled him to remain in hiding.
