Enemy of Mine
Every so often you get a story arc featuring a hero and villain temporarily putting aside their differences and forming something of a mutually beneficially alliance in the face of some greater evil or for something just as basic as survival, a valuable lesson in the form of "Not so Different" is usually a theme behind stories like this, maybe if the villain never had his or her "defining darkside character horizon" he or she could have been a hero or possibly a partner in another lifetime. The two may become close during their time spent together, sometimes developing intimate feelings and sometimes acting upon those feelings but not always. May lead to a lot of back-to-back badass moments and hero saves villain, villain saves hero. Sometimes the villain may pull a double cross on the hero at some point in the story, though the hero usually expects the betrayal. Though it's not uncommon for the villain to honor the terms of the truce either. This is probably my favorite kind of story telling device, it has its origins in the Arab proverb. "The enemy of my enemy is my friend"
Another phrase used to describe this is "War makes for strange bedfellows." This results in a scenario where foes must work together to achieve a common goal.
