[Batman & Robin] Mr. Freeze wants to cover the world in ice. Poison Ivy wants to cover the world in plants. Those two plans seem incompatible, why are they working together?

They both see Batman as a threat, and neither of them see each other as a problem. Once the Bat is out of the picture, they're both planning to betray each other as soon as they get a chance.

Mr. Freeze thinks he can get rid of Poison Ivy whenever he wants, because he can freeze her out. Poison Ivy is counting on the fact that underneath the suit, Mr. Freeze is a man like any other. And that means she can manipulate him now, and betray him once she's gotten what she wants.
