Nighthawk

Nighthawk was a member of the Squadron Supreme.

Avengers Assemble
Nighthawk was an alien superhero from a distant world where he was a member of a team of heroes similar to the Avengers called the Squadron Supreme. The people of their world feared their power and turned against them. As a final solution, Hyperion destroys his home planet along with his team on it, escaping into space in his Citadel.

Nighthawk when he first appears in the disguise of S.H.I.E.L.D. Agent Kyle Richmond. Using his position on S.H.I.E.L.D. as the Director of Interstellar Operations, Kyle secretly gets into S.H.I.E.L.D.'s database in order to obtain the contingency plan about the Avengers while trying to get Falcon to join up with his group. It also shown that he was aware of the Cabal that Hyperion was apart of. Using the contingency plans, he used a HYDRA robot loaded with a special chemical to disable Hulk, used a Hydrarobot to attach a Norn Stone to Thor's Mjolnir causing him to go through the Nine Realms, used a special code to knock out Black Widow, shut down JARVIS, disable Iron Man, and use a sonic grenade on Captain America's shield. Upon capturing Falcon and a cube that rose Hyperion's citadel, he heads to the citadel where he reveals his identity to Falcon while mentioning that Kyle Richmond was an alias. Nighthawk explains that he is the "architect" of the Squadron Supreme while Hyperion was the "hammer" of the group. After mentioning that the rest of the Squadron Supreme are heading to Earth, Nighthawk then uses Hyperion's citadel to fire a laser that starts heading to Manhattan while broadcasting to the world to surrender the Earth to the Squadron Supreme's protection or else lose a major city every day. In the nick of time, the Avengers show up after getting out of their traps. While Hulk and Thor work to shut down the citadel, the others fought Nighthawk where they managed to defeat him and remand him to S.H.I.E.L.D. custody. Outside of Nighthawk's cell, Nick Fury mocks the idea of Nighthawk being one step ahead where Nighthawk states that he's always one step ahead. This is proven right when Hyperion arrives and frees Nighthawk in front of Nick Fury. Nighthawk and Hyperion then leave to get their group together.

Using the Reality Gem, Doctor Spectrum alters reality so the Avengers are all criminals with darker costumes and the Avengers Tower is headquarters of the Squadron. Due to a spike in energy, Iron Man sees the real reality and manages to convince his team to come together. However Spectrum has created a machine that will give him complete control over reality, and plans to alter history so the Avengers were never born. Captain is able to get a hold of the stone and revert reality back to normal. The Squadron leaves with Nighthawk activating charges placed at the base of Avengers tower. The Avengers manage to prevent the structure from falling onto New York in time for J.A.R.V.I.S. to activate the repair systems.

In "Terminal Velocity," Nighthawk sends Hyperion to fight the Avengers as part of a diversion for Speed Demon to get specific information from the Stark Tower computers. After Hyperion and Speed Demon get away from the Avengers, Hyperion and Speed Demon meet with Nighthawk at the Squadron Supreme's hideout where Speed Demon gives Nighthawk the information he obtained.

In "Spectrums," the Power Prism that possessed Doctor Spectrum made its way back to Nighthawk. Upon the Power Prism no longer needing a host, the Power Prism forms a new body that resembles Doctor Spectrum as Nighthawk welcomes it into the Squadron Supreme. Later in "Midgard Crisis," Nighthawk learned from Zarda that her plans to sway an Avenger to their side didn't go well and that she was wrong.
