Marvel: I wish to be the One- Below- All.

A fan of Marvel, and a former USA marine goes on adventure.

The One Below All is the direct opposite counterpart of the One Above All. This has radically altered Marvel's cosmology since this makes the One Below All Marvel's first true Anti- God and as such, it is the unequaled embodiment of destruction, wrath and ruin.

The One Below All is also the true power behind the mutagenic factor of gamma radiation in Marvel, creating the gamma mutates, Hulk is obviously the most famous and most powerful. It was this very revelation that drove Brian Banner as he believed his son carried a monster gene, having caught a glimpse of the One Below All during her own experiment's into gamma radiation.

So far, Diana Addison has no true form, but she has very brief appearances where she can take seemingly any form she desires, though she favors the use of extremely abstract and terrifying visages.

There's no doubt that Diana Addison could further play her dreaded reputation as the true Satan of the Marvel MCU universe.

Despite her Satanic nature, Diana Addison apparent true form is actually the Goddess of creation, which is very likely symbolism to the One Above All's nature as both of an embodiment of destruction and the hidden, malevolent intellect behind the mutagenic nature of gamma radiation in the Marvel Universe.
