Quotes / Kryptonite Is Everywhere

Bass: I'm not calling Supes in on this... the guy's weak against magic and kryptonite. I'm pretty sure this Amon guy knows some magic, and any yahoo can get their hands on kryptonite. Heck, I bet this guy sells kryptonite ice cream.
Ice Cream Vendor: In two flavors! Regular, and now mint! Buy now!
Bass: See what I mean?

Spider-Man: You've already used kryptonite in a few of your movies. Shouldn't you move on to something different?
Superman: Oh, it's different this time. This time we have a whole MOUNTAIN of kryptonite!

Gold is lethal to Cybermen? What a rubbish weakness! Why do they even need a weakness? Doing this reduces from formidable mock humans to super hero villains that can be swiped down by their Achilles Heel. It's like saying throwing a bucket of water over the Daleks could finish them off…so they want to wreck havoc on Ocean World!

A young girl is possessed by a devil, and Constantine shouts, 'I need a mirror! Now! At least three feet high!' He can capture the demon in the mirror and throw it out the window, see, although you wonder why supernatural beings would have such low-tech security holes.

In a fight against Juggernaut and Cassidy in their spacious castle basement, Cassidy mentions the word 'tomb' to the X-Men.

Power Girl: Do either of you know where I can get some Kryptonite?
Lois Lane: I don't think so. I mean, Kryptonite is pretty rare. Every time Superman found a chunk of it, he wrapped it up in lead and threw it into space.
Power Girl: Just great. And there's no way of tracking where those chunks are, right now. If this was Earth-One, I could find the stuff within half an hour. It's practically as common as coal in that universe.
Jimmy Olsen: Not that common, Ms. Kara. But there's a lot more of it over there than there is here, from what Superman toold me. It must be rough, being a Kryptonian over there.
