The One Below All

The One Below All's powers and abilities

The One Below All is the source of the mutagenic form of Gamma energy and is able to possess Gamma Mutates; though it can only indwell one host at a time to directly influence people and the living world. While needing a host to directly affect the material world, It can subtly influence people and events in a physical reality where and when its strongest. It can push people when they're consumed by the more negative aspects of the psyche (like making two angry bar patrons attack each other and then stab Langowski despite almost no serious buildup causing Jackie McGee to note it seeming random). Puck mentioned that it had been stroking minds and moving things around to suit its plans. It was also able to reach Brian Banner before Gamma Mutates even existed when he was able to see a Green Door and catch a glimpse of the One Below All suggesting that it might have been manipulating the events of lives of Brian and Bruce Banner so that it would have a way of freeing itself from the Below Place years later. It has also been shown seemingly being able to increase its power with the anger and sorrow of others as when Hulk was thrown in a savage rage and Jackie McGee seeing her deceased father. This alludes to its phrase "I have all of the power you give me", meaning that the worse state a person is in, the more power and control it has. Even when restricted by the Green Door, the One Below All's power greatly eclipses that of other demonic entities such as Mephisto.

The One-Below-All can spawn entities called Qlippoth, which take on the appearance of peoples' loved ones and enemies in order to torment them, and can also regurgitate hordes of demonic monsters.
