10 Worst Things Doctor Doom Has Done In Marvel Comics

10. Attacking Wakanda for Vibranium
In his relentless quest for power and resources, Doctor Doom set his sights on Wakanda’s vast vibranium reserves. Rather than negotiating diplomatically, he allied himself with a militant Wakandan faction known as the Desturi and orchestrated a full-scale invasion. Doom’s forces overwhelmed Wakanda’s defenses, stealing a massive cache of vibranium. He planned to use the metal to enhance his technology and sorcery. Only the swift intervention of Black Panther and other heroes prevented the invasion from causing even greater devastation.

9. Ruling Latveria with an Iron Fist
As the monarch of Latveria, Doom maintains absolute control over every aspect of the nation. While he has brought technological advancement and stability to the country, his regime is a brutal dictatorship. Dissent is crushed mercilessly, surveillance is constant, and any opposition is met with severe punishment. Doom portrays himself as a benevolent ruler, but in reality, he governs through fear, propaganda, and oppression.

8. Manipulating Scarlet Witch for Power
During the ‘Children's Crusade’ storyline, Doom exploited Wanda Maximoff, the Scarlet Witch, during a time of emotional vulnerability. After she suffered memory loss, Doom convinced her that they were in love and planned to marry. His real motive was to access the Life Force within her, an immensely powerful source of chaos magic. If successful, it would have made Doom virtually omnipotent. His manipulation of Wanda showed his willingness to exploit others, regardless of the emotional or physical toll on them.

7. Killing Doctor Strange
In ‘Secret Wars’ (2015), Doom briefly aligned with Doctor Strange to preserve the remnants of the multiverse by creating a patchwork planet called Battleworld. However, when some heroes attempted to escape, Strange aided them in secret. Feeling betrayed, Doom murdered his former ally in cold blood. This act of treachery underscored his fragile ego and his ruthless intolerance for disobedience—even from friends.

6. Conquering Earth Multiple Times
Doctor Doom has, on several occasions, successfully conquered the Earth—albeit temporarily. In one instance, he used the mind-controlling powers of the Purple Man. In another, during ‘Secret Wars,’ he reshaped reality to his will as a self-proclaimed god. These conquests, while short-lived, reveal the true scale of Doom's ambition. He doesn't just want to rule a nation—he wants to rule everything.

5. Erasing Citizens' Memories on Battleworld
After constructing Battleworld from fragments of destroyed realities, Doom wiped the memories of its inhabitants. He stripped away their knowledge of their past lives, families, and identities, leaving only what suited his new world order. This act of mass mental erasure was done to ensure no one questioned his authority. By robbing people of their histories and autonomy, Doom demonstrated a chilling disregard for individual freedom and identity.

4. Experimenting on Asgardian Refugees
After the fall of Asgard, Doom offered asylum to displaced Asgardians. However, his "hospitality" was a cruel facade. He captured and experimented on several refugees, subjecting them to torturous procedures and cybernetic augmentation. Transforming living beings into unwilling test subjects, Doom mutilated and violated those under his protection, further showcasing his unethical scientific obsession and complete lack of empathy.

3. Sending Franklin Richards to Hell
In one of his most disturbing acts, Doom orchestrated the banishment of Franklin Richards—Reed Richards’ young son—to Hell itself. To do so, Doom sacrificed his own childhood love, Valeria, offering her soul in exchange for the power needed to carry out the plan. This was not just a physical attack, but a psychological assault on Reed and his family. Sending an innocent child to eternal damnation purely to hurt his enemy highlights Doom's unmatched cruelty and depravity.

2. Replacing Reed Richards During ‘Secret Wars’
After becoming a god on Battleworld, Doom went beyond conquest—he attempted to replace Reed Richards entirely. Doom declared himself the head of the Fantastic Four, married Sue Storm, and even became a father figure to her children. This grotesque impersonation of Reed was not just delusional—it was deeply invasive. Doom’s twisted desire to usurp Reed’s life revealed the depth of his envy and his obsession with being superior in every way.

1. Killing His Ladylove Valeria for Magical Power
Arguably the most heartless act in Doom’s long history of villainy was the murder of Valeria, the woman he loved. In order to gain the magical power required to torment the Richards family and banish Franklin to Hell, Doom willingly sacrificed her life. This act wasn't driven by desperation or necessity—it was cold, calculated, and entirely self-serving. To kill someone he truly loved for personal gain shows that there is no line Doom will not cross. It solidifies his place not just as one of Marvel's greatest villains, but as one of fiction’s most remorseless monsters.
