Why The Introduction Of Adamantium Is Such A Big Deal For The MCU
Adamantium Is One Of Marvel’s Strongest Metals
Adamantium’s introduction is a big deal for the MCU because of its sheer power. Itisa virtually indestructible steel alloythat can withstand most pressure and cut through almost any surface. Most notably, Wolverine’s skeleton is laced with adamantium, which is how he possesses his superhuman strength. In the comics, it was created by Dr. Myron MacLain when he mixed vibranium and an unknown catalyst, later being duplicated in a version without vibranium known as True Adamantium.
Vibranium has been the most powerful metalin the MCU since the franchise’s inception, but comic fans knew its rival would eventually come along. It was a highly-anticipated plot point, and with it coming so soon inCaptain America 4, it likely means thatvibranium will be taking a backseatin the MCU. Vibranium has served as the center of several conflicts due to its value and strength, but with how powerful and expensive adamantium is, the resource wars will only intensify as Ross foreshadows at his White House press conference.

The adamantium reveal inBrave New Worldwill be a huge moment for the MCU because it won’t just be the introduction of the long-awaited metal, but it will alsofinally address the Celestial massthat fans have been wondering about sinceEternals. The comic version of adamantium was man-made, but the fact that Celestials will be made out of the metal posesthe question of whom the creator of adamantium in the MCUwill be.Captain America: Brave New Worldwill be the perfect MCU project to explore how humans react to the powerful substance coming to light.
