Ultron: You think you're saving anyone? I turn that key and drop this rock a little early and it's still billions dead. Even you can't stop that.
Thor: I am Thor, son of Odin, and long as there is life in my breast...I am running out of things to say. Are you ready?
[Vision sucker punches Ultron with Thor's hammer.]
Vision: It's terribly well-balanced.
Thor: Well, if there's too much weight, you lose power on the swing.
Tony Stark: You listening? That little witch is messing with your mind. You're stronger than her. You're smarter than her. You're Bruce Banner.
[Hulk roars angrily.]
Tony Stark: Right, right, right. Don't mention puny Banner.
Chosen answer: This is a fairly US-centric gag. In Archie comics, the titular Archie has two competing love interests: Betty and Veronica. Given the Hulk/Banner's history with Betty Ross being able to calm him down, Tony Stark has named the containment system/Hulkbuster armor "Veronica".
