Witty Tony Stark Replies
It's pretty simple. Make up replies that Tony would say to something in an everyday situation, in battle, at parties, etc.
Enemy: "Any witty comebacks, Mr. Stark?"
*sonic booms fill the air, and several of Tony's Mark suits come flying in one by one*
Tony: "Oh...about forty."
"Let's see a swiss army knife do this!"
(shoots a drone)"Tag, you're it."
(referring to his weaponry) "Mine's bigger."
You wanted to be the hero. Now you gotta pay the price.
