Fictional historyEdit

In the Ultimate Marvel universe, the Triskelion is one of the first headquarters of S.H.I.E.L.D., and base for the Ultimates. Originally designed by British architect Norman Foster, the facility was to have been mobile like the Helicarrier, but the cost proved prohibitive. The Triskelion was partially destroyed by the Liberators, whose super-soldiers scuttled the S.H.I.E.L.D. Helicarrier onto the facility, though the Scarlet Witch used her powers to save the building's first three floors and everyone within them.[2]

While under repair, the Triskelion's prison was breached by the Green Goblin, who gathered Doctor Octopus, Electro, Sandman, and Kraven the Hunter to form the Ultimate Six.[3]

During the Ultimatum storyline, the Triskelion was attacked by suicide-bomber duplicates of Multiple Man until Hank Pym sacrificed himself to stop the clones. Shortly after Ultimatum, the Triskelion was undergoing another stage of repairs and became the headquarters of the Ultimates' replacements, the Avengers.

During the Avengers' tenure, the Triskelion was attacked by vampires, a battle in which with the entire facility was teleported to a desert in Iran. After the Iranian government protested, S.H.I.E.L.D. temporarily moved their headquarters to Stark Industries. With help from the European Defense Initiative, S.H.I.E.L.D. was trying to find a way to return the Triskelion back to New York City.

This Triskelion was finally left to the new pro-American, Iranian government after powered rebels had taken down the former rulers, as the way to threaten Russia, China, and the Arabic nations authorities.[4]

A new Triskelion was built in New York, and in other countries, such as one in Bangkok in SEAR (South East Asian Republic, another newly established superhuman-run state).[5]

The Triskelion in New York City was destroyed when Hulk escaped custody along with Reed Richards, but was rebuilt into a flying fortress using technology from Richards' Aleph-One.[6][7]

During the Secret Wars storyline, the Triskelion is destroyed when Hulk's Doc Green form used the Fastball Special with Colossus during the incursion between Earth-616 and Earth-1610.[8]

Other versionsEdit

The Marvel-616 version of the Triskelion debuted as part of the All-New, All-Different Marvel branding. Located off the coast of Manhattan, it has three wings radiating from a hub, each serving a different purpose. The first wing houses the ground crew for the Alpha Flight Space Program; the second, a Wakandan Embassy; the third, the headquarters of the Ultimates (unrelated to the team from Ultimate Marvel).[9]

The Triskelion is later revealed to host S.H.I.E.L.D. personnel, including a medical emergency team.[10]

  • The Triskelion is featured in films set in the Marvel Cinematic Universe:
    • The Triskelion first appears in the 2014 film Captain America: The Winter Soldier (2014) as S.H.I.E.L.D.'s headquarters in Washington D.C.'s Theodore Roosevelt Island, on Little Island at the foot of the Roosevelt Bridge. The base is taken over by Hydra during their uprising from within S.H.I.E.L.D. in order to use three weaponized Helicarriers to kill people they deemed threats.
