The Titan was known as the strongest and commonly revered as a undefeatable demon of overwhelming strength.
Little is known about The Titan which was introduced in Doom (2016). One of the only references to The Titan can be found in The Titans Realm where the skeleton of the deceased titan can be found. The Titan was enscribed to be defeated by the Doom Slayer in an earlier age.
- The Titan breed of demons may be either fallen angels or Nephilim, mentioned in the Bible; "2 Peter 2:4 4 - For if God did not spare angels when they sinned, but sent them to hell, putting them in chains of darkness to be held for judgment."
