The Source is a cosmic force and the source of everything that exists.[2] It is protected by the Source Wall, a barrier containing statues of those who fail to pass it.[3]
In The New 52, the emotional entities sacrifice themselves by entering the Source to replenish the emotional spectrum.[6]
In DC Rebirth, Perpetua is sealed in the Source Wall billions of years prior before being freed when it is cracked in Dark Nights: Death Metal.[7] Furthermore, John Stewart absorbs the Source's power and meets its physical form, which resembles Jack Kirby.[8]
