This actually sounds like a fun idea. How's this:
Name: ArmaGideon (Aka GUTS)
Power: A timeless cosmic celestial being inhabiting a human body whose stomach cavity contains a micro-black hole within the abdomen that is directly linked to the center of the universe; in which any and all matter can become consumed at a whim. The torso opens up as the intestines flail around like appendages; wrapping around potential victims and pulling them in. Intestines are also able to be manipulated as though they were tenticles and used in various ways. (ie; grappling, strangling, binding, ect.) Assumedly, to contain such a devastating entity would warrant an invulnerability to it; in which case making the host body virtually indestructible.
Back Story: The entity was awoken here on Earth (Gaya) in the bones of a man long dead since the days of the cowboys. ArmaGideon wrapped the bones with the sands of the desert and brought life back in to the frame work that once was. When A secret deck of mystical cards was discovered at a pawn shop by a young boy named Marcus Desmond; Marcus began to find that each card presented him with a different ability. Elsewhere a homeless woman by the name of Stacy Motese had awoken one morning to find a rash of tan, bizarre, markings covering her arms, shoulders, and spine; each wielding a different power relative to the deck of cards currently in Marcus Desmond's procession. The last of a demonic race of fairy kin had lie dormant until the markings on Stacy Motese began to surface. The last fairy awoke from her statue like form and with little time to find a host, enchanted an elderly man, stealing his body for her own as a means of transport. She resided in the mans throat; and though very powerful, was restricted by her host's age. Levitation replaced flight, and the ability to control the minds of others was reduced to making them brainless zombies. She needed to take over the body of Stacy Motese, and find the ancient mystical cards in order to take on her final form and for ever rule the universe. ArmaGideon arose from the depths of eternity to make sure that the fairy's destructive intentions never be brought to fruition.
Like Marvel could ever think of this kinda shit! LOL! Im either a total idiot or completely brilliant...
