Squadron Sinister

The Squadron Sinister is a fictional supervillain team appearing in American comic books published by Marvel Comics. The Squadron Sinister first appeared in the final panel of The Avengers #69 (October 1969), created by Roy Thomas and Sal Buscema. Squadron Sinister is a pastiche of DCs Justice League.

The limited series Squadron Supreme,[2] written by Mark Gruenwald, explains that the Grandmaster creates the Squadron Sinister modeling them on the already-existing Squadron Supreme of the Earth-712 universe.[3] The similarities also caused confusion in Marvel's production department, as the covers of The Avengers #85 (February 1971) and #141 (November 1975) "cover-blurbed" appearances by the Squadron Sinister, when in fact it was the Squadron Supreme that appeared in both issues.

The Avengers eventually defeat the Squadron and the Grandmaster abandoned them as a result.[4] The Squadron reappear in the title Defenders, reunited by the alien Nebulon. The villains receive greater power in exchange for the planet Earth, and create a giant laser cannon in the Arctic to melt the polar ice caps, thereby covering the entirety of the Earth's surface in water. The superhero team the Defenders are alerted to the scheme by Nighthawk and defeat the villains and Nebulon,[5] with Nighthawk reforming and joining the Defenders the following issue.[6]

After this defeat the three remaining members of the Squadron Sinister are teleported off world by Nebulon, returning with an energy-draining weapon. The villains plan to threaten the Earth again, but are defeated once more by the Defenders and the Avenger Yellowjacket.[7] During another brief encounter with several members of the Avengers, who seek a way to separate Doctor Spectrum's Power Prism from fellow Avenger the Wasp, the characters are revealed to have disbanded.[8]

While Nighthawk becomes an ongoing character featuring regularly in the Marvel universe, two of the other members of the Squadron make isolated appearances. Hyperion appears in the title Thor, battling the hero once again,[9] and features in Marvel Two-In-One in an encounter with the Thing.[10] Hyperion also travels to the Earth-712 universe and, after impersonating the Squadron Supreme's Hyperion for a time, dies in a heated battle with his counterpart.[3] The title The Amazing Spider-Man showcases the Whizzer's return, where he returns to crime with a new costume and the alias Speed Demon.[11]

The Grandmaster reappears and reforms the Squadron Sinister: an apparently resurrected Hyperion; a new Dr. Spectrum (Alice Nugent, former lab assistant of Henry Pym) and Nighthawk and Speed Demon, who have both had bad experiences with superhero team the New Thunderbolts. Courtesy of a phenomenon known as the Wellspring of Power - an interdimensional source of superhuman abilities - the Grandmaster increases the Squadron Sinister's powers and they battle the New Thunderbolts. Thunderbolts team leader Baron Zemo defeats the Grandmaster, and in the ensuing chaos the Squadron Sinister scatter and escape.
