After a swift - and slightly hurt - glare at the Doctor, the man in the armour returned his gaze to the green mass, who was still growling behind them "Are you okay Hulk?" he asked. After what could only be a confirming growl, the Hulk jumped out of the building, crashing into the opposite building, before sliding down its side, and began running down the street towards the chaos.

The man returned his gaze to the Doctor, who was staring at his suit avidly. "Um, what?" he asked
"Your suit, Its incredible" the Doctor stated
"Well duh, I did create it" he said, his eyes rolling, "The name's Tony Stark, seeing as you were ignorant of who's company your in.
and you are?"
I'm the Doctor, and this is Captain Jack Harkness. May I?" The Doctor listed their names indifferently, his eyes gleaming happily as they never left Starks suit.

"sure, but I just told you whos company your in, and your not even star struck?" Tony's eyes widening "Jesus, it really is the end of the world."

"I know who you are," purred Jack, walking up to Stark. "You're creator of Stark Industries. A Genius millionare, a philanthropist and a bit of a play boy, am I right?"

"In all facts, apart from I'm a billionare, not a millionare." sniffed Tony indifferently.

"Woah, check you out" muttered Jack shaking his head sighing. "hot but with a huge ego. Sorry, not my type."

"What too similar to you?" Muttered the Doctor smirking.

He stood up, smiling widely. "as I said before, your suit is incredible, and that man you called 'Hulk' that can't possibly be The Bruce Banner? He was caught in a blast of gamma radiation? Amazing he's still alive, pity about the side effect."

Tony Stark looked incredibly at the Doctor. "what so you know who he is, but not me?" he pouted.

"Of course I know who you are!" Shouted the Doctor, startling them "Tony Stark, Aka Iron Man. That suits keeping you alive, however, it looks like your suit is a little damaged." He pulled his screw driver out of his pocket, and with a swift movement and a flash of green light. He pocketed it. "There good as new, or as good as I can do in these current times."

Stark put his helmet back on and checked his on board monitor "Full power" He noted. "thanks" he muttered.

"You're welcome" Beamed the Doctor, "Now what was that you said about the end of the world?"
