Synopsis for "Extremis"

A S.H.I.E.L.D. team lead by Maria Hill is chasing a man named Mallen who has stolen a serum. He rambles that a real agent would not stand down, and that he'll show Fury he's fit to serve - he injects the serum into himself, and collapses. The agents track him down, only to find a strange cocoon on the ground - Mallen rises from it, with claws, pale skin and a feral look in his red eyes, he brutally attacks the agents, their bullets bouncing off him. The gang is heading home from school, realizing that it is soon over, Pepper says she can't imagine Rhodey as a military in the Air Force. She wants to join shield, but as they visit the recruitment office, it enters lock-down. The man arrives, aggressively attacking the S.H.I.E.L.D. personnel and muttering while he blasts lightning all around him. The friends decide to make a break for Rhodey's car where Tony's armor is stored so he can suit up. Seeing Iron Man, Mallen believes that defeating him will surely make S.H.I.E.L.D. recognize his abilities. With both amazing speed, reflexes and fire breath, Mallen soon defeats Iron Man and fries his heart implant using an electric attack. Black Widow arrives with S.H.I.E.L.D. backup, and Mallen flees the scene after injuring several more agents. As the friends watch on, Maria Hill extracts Iron Man whose vital signs are extremely weak.

Realizing they have to get his armor off to save him, Fury calls back through the armor comlink to get his friends on the line. Rhodey remotely opens his armor, allowing the doctors to help him. At the Helicarrier, Tony wakes up, bruised and weak, shocked that Fury has learned his identity - but the agents insist his secret is safe with S.H.I.E.L.D. They insist he is too beat up to continue the fight, his heart forever too damaged to endure the stress of fighting as Iron Man. Hiding in the streets, Mallen hallucinates, seeing Fury telling him about his "dissociative problems" and his being a failure - his rage towards Fury builds. Analyzing the fight in his mind, Tony wonders how Mallen can be so fast and durable, and he questions Hill and Fury about the serum he heard mentioned. Fury decided to reveal to them that Extremis is an experimental serum, using nanites to rewrite a person's biology and improve it, though every iteration so far is different. He reveals they have recovered Captain America and have him frozen in an ice block, and would possibly need Tony's help to revive him. Tony insists they inject him with a low dose of Extremis too, to help him heal and defeat Mallen. Fury thinks he is out of his skull, but the alarms soon go off - Mallen is attacking. They insist Tony should get some rest, but he has escaped to the Extremis lab, tailoring his own dose to modify his biology to enable him to tie the suit directly into his brain.

Rhodey, Hill, and Pepper bust into the lab, finding a cocoon on the floor in front of the frozen Captain America. Tony breaks out of it, freshly healed, even having regrown his heart. Maria Hill freaks out - he could have died, or worse, turned into another monster like Mallen. Fury and Black Widow arrive at Mallen's location to arrest him with the aid of four Mandroids. He quickly overpowers them, Fury muttering he should have never bought Hammer tech. On the helicarrier, doctors attempt to assess Tony's vital signs, but he is able to sense and affect technology around him, messing with their instruments. He successfully calls his suit and assembles it around him, the cybernetic link now feels apart of himself. Black Widow battles Mallen, but even as she breaks his neck, he quickly recovers, and Fury's blaster has no effect on him either. Iron Man arrives, knocking Mallen into a nearby restaurant where they battle. Tony's reflexes can finally keep up with Mallen's speed, and outside, using satellite uplink for a tactical advantage, he plucks a power cable up through the asphalt and shocks Mallen with the high voltage, finally knocking him out.

Iron Man offers to look into S.H.I.E.L.D.'s security, saying it needs some help. Nick Fury says he's looking forward to when Tony turns 18, he'll want him on a team he's been putting together.


  • Though similar in description to the mainstream continuity's Extremis, this serum seems to take effect after only a few minutes, where the original worked over 48 hours, or 24 hours after Stark removed the safeties.


  • When Fury mentions the team he is putting together, it could be alluding to formation of the Avengers.
  • Introduction of Mallen and the Extremis storyplot.
  • Captain America is recovered by S.H.I.E.L.D. though still frozen in ice in this episode.
  • Reed Richards is again being mentioned as a teacher at the university M.I.T.
  • S.H.I.E.L.D. agents Dum-Dum Dugan and Phil Coulson are briefly mentioned by Maria Hill.
