Onslaught has a number of supernatural powers, including the ability to manipulate people's minds and behaviour, superhuman strength and the ability to manipulate magnetism. He is also virtually indestructible, making him a formidable foe for any hero who confronts him.

The One above All is a comic book character created by Marvel Comics and is known to be the supreme being of the Marvel Universe. He is virtually omnipotent and omniscient and is considered by many to be the God of this universe. The One above All was first introduced in the comic "The One above All: A New Beginning", where it was revealed that he had been present in the Marvel Universe from the beginning and had been quietly influencing events. Although he often acts as a neutral figure, he has intervened directly in the lives of Marvel characters on occasion, such as when he granted supernatural powers to Doctor Strange or when he gave Peter Parker the chance to become Spider-Man again. The One above All is known for his ethereal appearance and great power, and has left his mark on the Marvel Universe as an important and fascinating character.
