Necro-Overs (ネクロオーバー Nekuroōbā) are humans who were brought back from the dead and turned into super soldiers whose physical capabilities in all areas surpass most humans and even some Dopants, as well being hard to damage and kill. However, they require regular injections of bio-stimulants to keep their bodies from breaking down. The research on these super soldiers was formed by a collaboration of both the Museum and Foundation X led by Maria Daido (who took the name Maria S. Cranberry when she took the fake identity of an Interpol agent to fool Philip) based on Raito Sonozaki's death and revival after falling into the true Gaia Memory.
