Well, JudoDave, I hope you meant the super-villain Black Knight, because he's coming up.
While in the jungles of Africa, Tony Stark was out testing one of his weapons, used for fighting terrorism. He accidentally stepped on a trap and the following events led him to adopt the guise of...
The Invincible Iron Man! #3: Money is Power Part 1
Money is power. The good can use it. One example is Tony Stark. He gives a lot of his money to charity and the needy. With his wealth he aims to advance mankind.
Money is power. The evil can use it. One example is Justin Hammer. He seeks to advance his own wealth, only giving money to improve his reputation. He would do anything to become the richest man.
Hammer's Mansion
Justin Hammer sipped his coffee, reading the business paper. Stark Industries was making more money again. The gray-haired man threw the newspaper onto the floor in anger. He must find a way to destroy Tony Stark. He thought about the situation for a while, until he came up with a solution.
He picked up a phone, dialed some numbers, a listened to a beautiful foreign voice. "Hello, this is Madame Natasha speaking."
"Madame, this is Justin Hammer. I have a job for you."
A Ball
Tony Stark was enjoying the ball. He was hosting it and there were so much prominent people. Henry Pym, a scientist, was dancing with Janet Van Dyne, his fiancée. Obadiah Stone was scratching his bald head while talking to Kyle Richmond. What caught his attention the most a beautiful Russian woman and a mustachioed Englishman.
"May I have the pleasure? I am Tony Stark, the host of this ball." he asked as held out his hand. The Englishman shook it. "I'm Nathaniel Garrett, descendant of the medieval legend the Black Knight, and this is Madame Natasha from Russia.
As Tony Stark shook hands with the brown-haired lady, he studied her. She wore a fashionable black dress and her arms seemed to have some muscles in them while still looking delicate.
Suddenly Justin Hammer intervened. "Excuse me, Mr. Stark. I have an appointment with this fine young lady." The corrupt businessman smirked as he led Madame Natasha away and started dancing with her.
Mr. Stark started feeling a little lovesick, so he secretly prepared some special hearing devices he used as Iron Man to eavesdrop on Natasha. He was shocked when he heard the following conversation.
"What am I supposed to do, Mr. Hammer?"
"Find the plans for Stark's latest projects and then destroy the machinery... do it tonight. That should put me at the top."
"And what is my pay?"
"Oh, I should say $300,000,000."
"I'll take the job."
Tony went out of the room. Norman Osborn, leader of Oscorp, tried to stop him for a conversation, but the man wearing a green suit was distracted by J. Jonah Jameson. This enabled Tony to get to his car. Jarvis and Hogan asked if he needed anything, the latter wanting to drive the millionaire. Mr. Stark said no and jumped into a car, speeding towards the Stark plant.
The Stark Plant
Iron Man waited for Madame Natasha. He didn't want to harm her, just talk her out of destroying his company. The armored avenger was starting to feel sleepy, but he refused to give in. As his eyes started to close some, they popped open. A red beam was hitting his security camera, malfunctioning them. A black female figure swung in, noticing the superhero.
'So you must be Tony Stark's bodyguard! Well, it does not matter!" She exclaimed in her Russian accent. "Prepare to meet death at the hands of the black Widow!"
The female mercenary swung on a rope-line of hers and surprisingly kicked the heavily armored Iron Man into an electronic panel. Electricity swirled everywhere and the Black Widow was surprised when the man seemed unharmed.
"How—"
"Simple, Madame. I run on transistors, so electricity doesn't do much to be unless it's concentrated in mass energy. The black Widow recovered from her surprise and snatched some papers off Stark's desk, swinging out of the window she came in through. Iron Man lunged after her, but staggered when a heavy grenade was thrown at his face and exploded.
"Alright, Widow! I've been trying to not be so rough to you since you're a woman, but now I'm going to get you!"
"Not quite, Iron Man!" shouted the Black widow as she exploded an experimental tank with another grenade and jumped onto a warehouse roof. "The black widow spider has a deadly sting and I have copied it! Here!"
She shot a black dart from a wristband, but it broke against the metal armor of Iron Man.
"Impossible," she said under her breath.
"Now, lady, I'm going to blast the roof from under your feet!" Red repulsor beams destroyed the roof that Madame Natasha was standing on and the beautiful woman started falling. But she fired a cable that stuck to the roof and swung out in an impossible maneuver, escaping a charge from Iron Man.
"What th—Ungh!" A grenade hit the avenger's head and knocked him onto the floor. The black Widow fled from the factories and power plant, knowing that she would probably be caught if she stayed. She did manage to destroy a few more pieces of valuable equipment, but not enough to end Tony Stark's company.
Justin Hammer's Mansion
"Your room is down the hall three doors to the right, Mr. Garrett."
"Thank you, Mr. Hammer."
Nathaniel Garrett entered his room and closed the door behind him. He then opened a suitcase, in which was a medieval knight's helmet.
Stark's Office
"What happened here, Mr. Stark?" asked Jarvis, the butler.
"Iron Man had a fight with a woman," Stark answered, not saying the woman's name. "She was driven off."
"Happy" Hogan came in with his usual frown. "Hey, boss, I was wondering if I can actually drive you somewhere. I'm you chauffeur, ain't I?"
"Sure, Hogan. Drive me to my mansion."
The two got into a sleek car and drove away from the plant.
Justin Hammer's Mansion Again
"Mr. Garrett, what is all the noise about? If you keep it up I'll send you to a hotel instead of this free room you're having! For heaven's sake answer me!"
Justin Hammer was angry. First Madame Natasha failed, and now Nathaniel Garrett was doing noisy things in his room like a five year old. He finally opened the door. "Mr. Garrett, for the last—" He was cut off in mid-sentence. Standing before him was a winged horse, neighing and stomping its hooves, and on top of it was a medieval knight in black armor with a long lance.
"I, my angry friend, am the Black Knight! And I'll prove that I'm the right one to hire for the destruction of Tony Stark by destroying... IRON MAN!"
Next, the Black Knight strikes in: Money is Power, Part Two!
