After 85 Years, Marvel Kills Off A Beloved Superhero Icon

A major Captain America character and longtime Avenger seems to die in Marvel's main continuity. The Avengers earn their reputation as Earth's Mightiest Heroes thanks to unparalleled power. But no matter how godlike they appear, every member of the Avenger has at least one major vulnerability that their enemies can exploit. Some of these weaknesses are shockingly mundane, such as the mere fact that half of the team can be taken out by regular, well-placed bullets. It may not seem like it, but the Avengers' defenses are constantly tested, and on rare occasions, they fail. When the Avengers fall, each death leaves an irreversible mark on the team's history. Captain America's assassination on the courthouse steps following Civil War finished breaking the superhero community's moral compass and created a leadership void that resonated across every major title. Hawkeye, Scott Lang, the Vision, and Jack of Hearts' deaths in Avengers Disassembled marked a point of no return for Earth's Mightiest Heroes in one of the most tense eras in their sixty-three-year history. In Marvel's main continuity, every major Avenger has died at least once, including the recently deceased Thor. Even though death is eventually reversible in the Marvel Universe, no one is ever fully safe, and superhero deaths are even more shocking when their respective stories choose not to tease them beforehand. Bucky Barnes Seemingly Dies In A Nuclear Bomb Explosion, And No, It's Not A Multiversal Variant Avengers: Armageddon #4; Written By Chip Zdarsky; Art By Delio Diaz, Frank Alpizar, And Jesus Aburtov Thaddeus Ross fast-tracks his global takeover by collaborating with Russia and reactivating all existing nuclear bombs across the world, and David Colton turns the situation even more volatile by deciding to neutralize every single warhead. Every single member of the Avengers condemns Colton's decision, but to their surprise, Bucky Barnes supports the idea. While the Avengers manage to stop a few missiles, another lands right where David Colton and an enhanced Red Hulk are fighting. Unfortunately, Bucky Barnes is also hit point-blank by the nuclear explosion. The page depicting the nuclear explosion features Bucky and Captain Marvel taking the full impact, but while Carol Danvers is shown resisting the shockwave, Bucky's body appears to be disintegrating, his metal arm flying off and the rest of his body getting torn to shreds. When David Colton talks with his mother on a different plane, he admits "people are dead" around him, which likely includes Bucky. Miracleman's utopian society allows medicine to reach unprecedented heights, but not even the Miracleman from Alan Moore's run could restore Bucky Barnes from a nearly point-blank nuclear explosion. Sadly, The Winter Soldier's Last Twist Makes Sense Bucky Took The Risk And Paid The Price Bucky Barnes’ decision to align with David Colton’s extreme nuclear disarmament initiative reflects the grim pragmatism he learned after recent comic events. Having recently captained a highly volatile roster of the New Avengers, Barnes witnessed firsthand the threat of the Jackal's Killuminati, a cabal of weaponized clones modeled after Earth's most powerful thinkers. Fighting the Killuminati exposed Bucky to the devastating reality of weapons of mass destruction falling into erratic hands, made exponentially worse when Bucky found his trust broken by Black Widow's manipulation. Bucky's remaining faith in institutional oversight and conventional superhero restraint likely convinced him that conventional diplomatic channels are entirely useless when confronting global annihilation. While Wolverine argues that forcefully stripping the globe of its deterrents sets a dangerous precedent, the Winter Soldier sees the impending apocalypse as a fight-or-die situation. Bucky Barnes' long history of fighting tyrants has taught him that as long as these apocalyptic payloads exist, there will always be someone ready to weaponize them. Backing David Colton's godlike Miracleman persona to shoot down every nuclear bomb is a gamble that could have rid the Earth of one of its most dangerous threats. Unfortunately, Bucky's gamble didn't pay off. What do you think about Bucky Barnes' apparent death?
