Portuguese man o' war
The Atlantic Portuguese man o' war lives at the surface of the ocean. The gas-filled bladder, or pneumatophore, remains at the surface, while the remainder is submerged. As the Portuguese man o' war has no means of propulsion, they move according to the winds, currents, and tides. Although they are most commonly found in the open ocean in tropical and subtropical regions, they have been found as far north as the Bay of Fundy, Cape Breton and the Hebrides.
War (Marvel Comics)
Kieros was a young Vietnam War veteran who was paralyzed in combat. He was kept in a hospital and placed in an iron lung, but felt as though he was betrayed and forgotten by his country. Apocalypse appeared to him one day and offered him the ability to move and to get revenge on those who had tossed him aside. He accepted the offer and was indeed given the ability to move again, which allowed him to use his mutant power—the ability to create explosions through kinetic contact, usually by clapping his hands together—in Apocalypse's service as his Horseman of War. He often bickered with one of the other Horsemen, Famine, and disliked her total lack of obedience.
