"CONSUUUUUUUUUUUUUUUUME!"
Despite being aged down, Iron Man's life is still filled with many nightmares, some from his enemies and others of his own creation.- Rhona, having become the Teen Genius equivalent of a school shooter during episode 38, "All the Best People Are Mad". Tried to gas Whitney, cut Rhodey in half, vaporize Pepper and electrocute Happy.
- And she did something similar once before, so she probably has quite the body count behind her.
- Mallen in episode 42 "Extremis", once he takes the Extremis formula. The creepy cocoon he comes out of, his black eyes with red irises, his decomposed skin, the growing insanity, not to mention his enhanced strength, super-speed, and lightning and heat powers, make him one of Iron Man's most terrifying foes.
- There's also the sheer insanity in his actions.
- Pretty much everything about Technovore. Not to mention how its driven to eat any technology to improve itself and will even eat humans if it feels the need."Cooooooonsuuuuuuuume...!"
- MODOC from season 1, episode 21 "Designed Only for Chaos" itself is pretty scary. It's a technologically advanced Humpty Dumpty that, to put it simply, Mind Rapes you and steals everything in your head.
- You didn't misread that, people. This show actually manages to make MODOC legitimately threatening.
- Also, this version of MODOC looks just plain creepy. It's especially unsettling because this was never a problem with MODOC.
- Justin's beginning as Titanium Man in "Titanium vs. Iron", has him brutally blow-up Iron Man's empty armor, and actually express disappointment there are no blood splattering everywhere.
- Justin Hammer's zombie gas in "The Hammer Falls" and its effects. Also, Justin's Villainous Breakdown may qualify. He deserves it, but God is his Sanity Slippage creepy.
- In episode 47 "The Hammer Falls", Iron Man drops Justin Hammer from high up into the air, into his building. He makes no move to catch him, proving that he wasn't simply trying a scare tactic; if Hammer didn't grab onto something, he genuinely might have died. Afterwards, Mr. Fix took the remote that Hammer tried to use, shoved Hammer into a pod previously used on Killer Shrike, and zombified him. Iron Man then shot the computer that Mr. Fix was inhabiting. Earlier in the series, Mr. Fix was removed from his body and transformed into an AI, being trapped inside of a computer. The same computer that Iron Man just destroyed. In other words, Tony pretty much killed Mr. Fix and tried to murder Hammer with no remorse.
- Killer Shrike planning to murder a bunch of hostages unless Tony kills himself by blasting his head off with his own repulsors.
- The extra-dimensional demon Dr. Doom summoned in his second appearance in episode 46, "Doomsday".
- Dr. Doom is exponentially creepier in the show than in other incarnations, coming off as a towering anger-prone Invincible Villain due to his extremely advanced quantum technology built into his suit and there's no Fantastic Four to stop him in this verse. He gets the Too Powerful to Live write off when he ends up having his own soul trapped in the aforementioned demon's dimension, presumably forever.
- Magneto gets some credit for being able to find "Annie" in episode 43, "The X-Factor". No matter where she runs, claiming that he can sense the iron in her blood like a fingerprint. All in Creepy Monotone.
- Tony Stark's armor AI becoming a crazed Yandere for Tony in the same vein as the sentient, psychotic Safe Armor brought to life by lightning in the controversial comic story, The Mask in the Iron Man. During its short experience with sentience, it put Pepper on its hit list based solely on the number of texts she sends Tony and tries to lure her to the lab so it can kill her, almost kills Rhodey when he tries to debug it, and tries to lock Tony inside itself to protect him from himself. The fact its end goal is to be Tony's Robotic Spouse is described as creepy in-verse, especially with its statement that all of Tony's "biological needs will be met" in her care.
- Andros Stark in episode 44 "Iron Man 2099", Tony's grandson from a Bad Future that wants to murder Tony to ensure the future he came from never happens. Nothing in the modern era can stop him due to his future technology and he becomes the only one of Tony's enemies to succeed in murdering him, on-screen no less in front of all of his friends.
- Thaddeus Ross' plan for the Hulk in episode 48 "Rage Of The Hulk". Capture the Hulk, kill him, dissect his corpse, and use his remains to replicate an army of Hulks under Ross' control.
- Watching the Makluan Overlord's son being vaporized near the end of "Dragonseed".
