Blackout

A villain who debuted as an enemy of Dazzler, this Blackout possesses darkness-manipulating abilities and later became associated with the Masters of Evil, most notably playing a role in the landmark 'Avengers: Under Siege' storyline alongside Baron Zemo's assembled team.

Born in the thick of Marvel's Bronze Age, Blackout made their debut in Dazzler #32 in 1984, brought to life by the creative team of Jim Shooter, Mike Carlin, and Mark Bright. Over a publishing history that stretches a remarkable four decades to 2024, this villain has haunted the Marvel Universe in some genuinely pivotal company — sharing pages with heavy hitters like Captain America, Captain Marvel, and the scheming Moonstone/Karla Sofen. Most notably enshrined in Avengers: Under Siege, one of the most celebrated Avengers storylines of the era, Blackout is the kind of deep-cut Marvel menace that rewards the curious collector who digs past the headliners into the darker corners of the universe.
