As the Avengers rally to thwart Emperor Supreme Doctor Doom’s ambitions for global domination, another formidable team of villains is emerging—the Masters of Evil. This notorious group, assembled from the depths of Marvel’s villain roster, aims to vanquish their heroic foes, and they certainly embody their sinister moniker in their actions.
The upcoming Avengers #25, slated for April 23, 2025, crafted by the talented duo of Jed MacKay and Valerio Schiti, sees the Avengers gearing up for a showdown against Doctor Doom, who has finally set his strategic plans into motion.

Marvel has tantalizingly unveiled the cover of this “giant-sized”edition, signifying the emergence of a new version of the Masters of Evil. Initially established by Baron Zemo, the original team comprised some of the Avengers’ most formidable adversaries. However, over time, its members were supplanted by less threatening foes, rendering it almost a parody. Now, the latest incarnation promises to be far deadlier than appearances suggest.
Madcap
Debuted In: Captain America #307 (1985) by Mark Gruenwald and Others





Madcap is a character devoid of a discernible identity, who thrives on psychological chaos. His origin story is as bizarre as his personality; during a fateful church trip, he was the lone survivor when a bus was destroyed to conceal an experimental chemical release. The hyper-healing enzyme left him unable to feel pain, a condition that spiraled him into deep survivor’s guilt and a reckless embrace of nihilism.
With no sense of purpose, Madcap indulges in madness and whimsy, wielding a power that drives those around him to insanity. A confrontation with Ghost Rider even exposed him to pain again, igniting a desire to experience that torment repeatedly. His sole fixation became inflicting suffering upon Deadpool, as he sought to bring chaos into Wade Wilson’s already tumultuous life, leaving devastation in his wake. Yet, after witnessing Deadpool’s self-destruction, he moved on, satisfied.
Dreadknight
Debuted In: Iron Man #101 (1997) by Bill Mantlo and Others

Bram Velsing, a brilliant scientist from Latveria, transformed into the fearsome Dreadknight after escaping the vengeful grasp of Doctor Doom, who punished him for his rebellious thoughts. After fleeing, Velsing found refuge among a collection of genetic experiments led by Victoria Frankenstein, who assisted in his recovery. Driven by vengeance against his former master, he reclaimed a long-lost winged horse and evolved into a knight-themed villain armed with a high-tech lance.
Eventually, as chaos erupted in Latveria, Dreadknight saw a fleeting opportunity to seize power, only to be thwarted by an improbable alliance of Spider-Man and Silver Sable. Despite his failure, his mechanical genius remains a powerful asset to the Masters of Evil.
Mister Hyde
Debuted In: Journey Into Mystery #99 (1975) by Stan Lee and Others

Dr. Calvin Zabo, also known as Mister Hyde, is another cunning villain with a history within the Masters of Evil. A physiologist gone rogue, Zabo invented the “Hyde Formula” to transform himself into the superhuman Mr. Hyde. His unethical experiments against impoverished individuals make him a monstrous figure, one who invariably provides heroes with formidable challenges.
Though not always a tremendous threat in isolation, his tainted legacy includes fathering Daisy Johnson, known as Quake, and helping spike the rise of Ghost Rider following a notorious confrontation in Los Angeles. Hyde’s morbid fascination with torment and disregard for human life solidify him as a key player in the team.
Exterminatrix
Debuted In: Marvel Boy #1 (2000) by Grant Morrison and Others

Oubliette Midas, once a victim of hideous grooming at the hands of Doctor Midas, evolved from a tormented girl into Exterminatrix, a consummate killer and assassin. Her upbringing was rife with trauma, turning her into a monster nurtured by her father’s cruel lessons. Despite her horrific tendencies, a pivotal moment reveals her vulnerability when she learns that Doctor Midas is not her biological father, highlighting her tortured psyche.
Though capable of profound empathy, her emergence in the Masters of Evil suggests a chilling complexity; her prior emotional awakening might serve more as a strategic guise than true remorse.
Mad Thinker
Debuted In: Fantastic Four #15 (1963) by Stan Lee and Others

The enigmatic Mad Thinker is a criminal mastermind in robotics and probability analysis whose genius rivals that of a supercomputer. His ability to calculate odds rapidly has made him a longstanding adversary to numerous superheroes, especially the Fantastic Four. Lacking a defined ambition beyond chaos, he often collaborates with other villainous intellects.
The Mad Thinker’s obsession with creating synthetic life forms, fueled by experiments with the original Human Torch, underscores his focus on technological domination. Together with the other Masters of Evil, his cold, calculating nature might be essential for executing sinister plans.
Doctor Doom’s Masters of Evil Are Unhinged Animals
These Villains Don’t Have to Be Powerful to Be Unstoppable

Doctor Doom’s new iteration of the Masters of Evil is marked by a chilling blend of intelligence and a merciless drive that rivals their predecessors. Their signature cruelty diverges from typical villainous ambition; each member presents their unique flavor of horror. As Doom positions himself as a supposed “savior” to the world, he manipulates this remorseless team from the shadows.
With Doom tightening his grasp, the Avengers will be stretched thin as they face the devastation reaped by the Masters of Evil across the globe.
Anticipate Avengers #25, coming April 23, 2025, for a deeper dive into this thrilling conflict.
