4. Oracle

Tech-iest superhero is a good tagline, but when your entire "thing" is operating a huge, computer-based weapon, you really do not want to get hacked.

And if there's one DC hero who could get into The Iron Man and bring it down from the inside, it's Barbara Gordon, aka Batgirl, aka Oracle. Even hidden away in a wheelchair in her secret Birds of Prey hideout, Stark wouldn't know what hit him. By the time he found Barbara, he'd be too busy playing an involuntary game of Stop Hitting Yourself to do anything about it.

Tony's suits are pretty darn hack-proof. I don't even think Batman could do it. But Oracle's whole thing is that she’s a computer genius. She has the hard advantage in this one. Tony can throw up firewalls and use as much Norton Antivirus as he wants, but when Oracle turns her sights toward you, there's nothing you can do.

Even wheelchair bound, Barbara could bring Stark to his knees.
