- "I am humanity's salvation, a savior giving purpose to a lost species that deserves far less. I. Am. Deimos."
- — Deimos in Demon Within
Deimos was accidentally summoned alongside his sister Dolos from Malum by the Corvus project. He merged Nova 6 and Element 115 To create Virus 61-15 and began his plan to turn all of humanity into an undead army to finally kill Dolos. Deimos was created at the Coalescence Corporation HQ in Singapore during the first Corvus Project, and later he contacted Sebastian Krueger and Yousef Salim in order to create New Corvus, inhabiting the new body and taking control of the Undead Armada after the 2060 Coalescence Disaster. He then waited 10 years and in 2070 possessed the bodies of John Taylor, Sarah Hall, Peter Maretti and Sebastian Diaz in order to create a Unification between the Winslow Accord and Common Defense Pact to unite Mankind against his Armada as he saw Humanity as a violent species which divided Earth and began Conflicts for no reason and wanted to reduce Humans on the Planet to only 400 million scattered across Earth to maintain the Winslow Accord-CDP Alliance created at the start of the 5-year Undead-Human War.
