Who are the superheroes using adamantium alloy?
Adamantium is a steel compound in the Marvel universe. Completely indestructible, the compound is used by superheroes to protect themselves against the most dangerous attacks of their enemies. Adamantium is closely associated with Wolverine’s skeleton and his claws, but it is also used by X-23 (the “female Wolverine,”) the rapier of Citizen V, and some weapons used by Iron Man. Villains also use Adamantium, especially foes of Wolverine and the X-Men like Constrictor and Lady Deathstrike. The outer skin of Ultron, who fought Captain America and the Avengers, is made of true Adamantium. You can read more about Adamantium here: http://www.marveldirecto …
