Scagdead (or "Skagdead") was a B.O.W. created due to infection from the t-Abyss virus and subsequent mutation of a human body that possessed a strong resistance to the virus (only exhibited by approximately 1 out of every 1000 people).
History
The Scagdead was first recorded in 2004 during the bioterrorism attack on Terragrigia. It was observed by Jessica Sherawat, who detailed it in a "t-Abyss Report" to the Global Pharmaceutical Consortium. It was observed a year later in 2005 on board the Queen Zenobia. The ship's communications officer had mutated into a Scagdead and locked himself inside a small storage room. He broke out, but was destroyed by Jill Valentine and Parker Luciani of the BSAA. Two other subjects were observed aboard the Queen Semiramis and destroyed by Chris Redfield and Sherawat.
The unique process of the creation of a Scagdead, which requires a rare human host, is believed to be connected to similar traits exhibited by the Progenitor virus, which adapts to superior DNA and endows superhuman abilities to human hosts, and the t-virus which requires adaptable genes in order for a human to become a Tyrant.
Attributes
The host's resistance to the virus only slows it down and does not stop its advance entirely. When humans are infected, they suffer from a high fever then develop tumors around their shoulders and necks. These symptoms happen a few days or weeks after being infected, and as the infection advances the host gradually loses consciousness. The hosts are aware they are being taken over by the virus, but they cannot do anything about it. Even after the virus has completely infected the host and taken complete control, the head of the host mutters words unconsciously, as if they are sleepwalking.
