Space Phantom

A mysterious alien from Limbo, the Space Phantom possesses the ability to perfectly imitate any living being, temporarily banishing the original to Limbo in the process. He first clashed with the Avengers as an agent of mischief, using his shapeshifting power to sow chaos and discord among Earth's mightiest heroes.

Few villains can claim they crashed the Avengers' party as early as issue #2, but Space Phantom made that audacious Silver Age entrance courtesy of Stan Lee and Jack Kirby in 1963 — practically at the birth of Marvel's mightiest team. This shape-shifting menace has haunted Marvel's cosmos ever since, racking up appearances across The Avengers, Avengers Forever, and Beyond! over an extraordinary six-decade span that speaks to genuine staying power. With five key issues to their name and a rogues' gallery of co-stars that includes Thor, Iron Man, and Janet Van Dyne herself, Space Phantom is woven into the very fabric of Avengers mythology. If you love the grand, weird ambition of early Marvel cosmic storytelling, this is a character absolutely worth tracking down.
