The Combine

# Wallace Breen (The False Prophet): Breen can be associated with the demon Bael, who, according to The Ars Goetia, appears in various forms and grants the power of invisibility. Breen's collaboration with the Combine and manipulation of humanity reflect Bael's deceitful nature.
# Combine Advisors (The Puppet Masters): These enigmatic beings can be likened to the demon Paimon, known for his knowledge of the arts and sciences and granting visions of the future. The Advisors' advanced intelligence and ability to control other species mirror Paimon's powers.
# Wallace Breen (The Cult Leader): Breen's collaboration with the Combine and manipulation of humanity can be likened to the cult leaders in Lovecraft's stories who worship and serve the Old Ones, often deceiving others for their dark purposes.
# Combine Advisors (The Eldritch Abominations): The Advisors' otherworldly appearance and advanced intelligence can be compared to the Old Ones or Elder Gods from the Cthulhu Mythos, such as Cthulhu or Yog-Sothoth. These entities possess immense power and knowledge, far beyond human comprehension.
# Combine Overwatch (The Minions): The Overwatch forces can be associated with the various humanoid or hybrid creatures that serve the Old Ones in Lovecraft's works, such as the Deep Ones or the Mi-Go. These minions carry out the will of their malevolent masters, often with little regard for human life.
# Headcrab Zombies (The Possessed): The transformation of humans into headcrab zombies can be likened to the victims of possession or mind control in Lovecraft's stories, such as the residents of Innsmouth who are transformed into Deep One hybrids.
