The Harrowing Transformation: Archangel’s Dark Descent into the Role of Apocalypse’s Horseman

Archangel, once a valiant member of X-Force, found himself unwittingly ensnared in a treacherous fate when he was chosen by the malevolent Apocalypse to become the Horseman of Death. Little did he realize the profound consequences that would accompany this transformation. As Archangel partook in the blood-soaked missions of X-Force, he gradually felt the insidious pull towards evil. It was later unveiled that the team’s act of eliminating a clone of Apocalypse triggered an Ascension Protocol, intended to mold Archangel into the very embodiment of Apocalypse himself.

Embracing his new role, Archangel donned the mantle of the new Apocalypse, wielding authority over Clan Akkaba, the dreaded Final Horsemen, Dark Beast, and Genocide. Together, they unleashed devastation upon a small town in Montana, obliterating it entirely and reshaping the land into a twisted domain known as Tabula Rasa. Inevitably, this malevolent force clashed with X-Force in a fierce battle.

However, a glimmer of hope emerged when Psylocke, a member of X-Force, managed to administer a cure to Archangel. Piercing him with a Celestial Life Seed, she initiated his salvation.

 10.  Scarlet Witch

Unleashing Chaos: Scarlet Witch’s Disturbing Descent

Among the Avengers, no member has ignited more controversy than Scarlet Witch. Unlike other characters who require forays into alternate universes to encounter their most malevolent versions, fans need not venture beyond the realm of Earth-616 to witness the darkest facets of Wanda Maximoff. Within this continuity, Scarlet Witch has committed unspeakable acts, with her most notorious transgressions occurring during the infamous Avengers Disassembled storyline.

While Scarlet Witch had previously assailed the Avengers, her assault during this particular event proved far more devastating. With ruthless intent, she coldly eliminated three of her fellow Avengers, marking this assault as her most heinous to date. What made matters worse was the revelation that Scarlet Witch acted of her own volition, free from any external possession or influence. This attack on her comrades was driven solely by a vengeful agenda, unclouded by external forces.

The Darkest Iron: The Villainous Reign of Civil War’s Iron Man

Within the vast tapestry of Marvel events, few have had such detrimental consequences for characters as Civil War, which birthed the most nefarious incarnation of Iron Man. What sets Civil War Iron Man apart is the chilling fact that every action he takes is driven by his own volition. He willingly betrays his closest allies in pursuit of power, collaborating with villains and constructing a prison in the forbidding depths of the Negative Zone to incarcerate those once considered friends.

Upon assuming control of S.H.I.E.L.D., Iron Man becomes consumed with apprehending Luke Cage’s New Avengers, to the point where he remains oblivious to the Skrulls’ insidious takeover. Throughout his tenure as the leader of the Superhero Initiative, Iron Man’s primary objective revolves around validating his beliefs and imprisoning all who dare to disagree. His deeds surpass even the audacity of common villains, blurring the line between his reign and the despotic rule of Norman Osborn. This stark comparison epitomizes the depths to which Iron Man descends during this tumultuous period.

His actions leave an indelible mark, tarnishing his reputation as a hero and illustrating the corrosive nature of power when it falls into the wrong hands.

This monstrous entity was a fusion of Magneto and Xavier, a result of Xavier wiping his enemy’s mind. Onslaught nearly obliterated the Marvel Universe’s heroes, showcasing the extent of his danger. As an independent psychic parasite, he has since resurfaced multiple times, continuing to pose a significant threat.

 13.  The Maker

The Ultimate Universe stood as a daring experiment, unveiling a fresh superheroic narrative within Earth-1610 for contemporary readers. In due course, the Fantastic Four made their entrance, showcasing their greatness as heroes. However, tragedy struck when Sue Storm fell victim to Magneto’s assault on humanity. This catastrophic event caused Reed Richards to plummet into a downward spiral, transforming him into the malevolent figure known as the Maker.

The Maker subsequently transcended into the 616 universe, engaging in countless battles against numerous heroes. While the 616 version of Richards had always exhibited a somewhat amoral disposition, the Maker personified a complete absence of morals, evolving into an abominable monster. The loss of his beloved Sue shattered him, amplifying his anguish further when he realized that things could have unfolded differently, intensifying his torment.

 14.  Hydra Captain America

Marvel’s endeavors to introduce surprising plot twists don’t always achieve the desired impact, despite their ability to captivate the pop culture scene. One such twist occurred when Captain America disclosed his affiliation with Hydra. Leveraging his tactical acumen and esteemed status as a revered hero, Cap exploited his position to seize control of S.H.I.E.L.D., instigating a series of events that granted him dominion over the United States and unveiled his allegiance to Hydra before the world.

Utilizing his influential position, Captain America assembled his own team of Avengers, which included the likes of Odinson, Scarlet Witch, and the Vision. Together, they labored alongside Cap, striving to prevent the occurrence of even more dire circumstances.

However, the situation took a turn for the worse when Weapon X encountered his world’s Death Seed. Believing he could wield its power without repercussions, he made the fateful decision to embrace it. Alas, this proved to be an immense error, as it transformed him into the new Apocalypse. The X-Force of the 616 universe lent their aid to the X-Men of Weapon X’s reality, engaging in a relentless battle against him. However, it would take some time before Weapon X could ultimately be vanquished.
