Lana Kane is the other top agent at ISIS and just happens to be Archer's ex-girlfriend.  She's a curvaceous black woman that despite her ridiculous physical and mental abilities is always second fiddle to Malory's favorite agent and son.  Most notable about her?  Besides her fake boobs?  Her giant hands.

Lana Kane Quotes

Archer: Brain aneurysm.
Lana: What's a brain aneurysm have to do with walking around in a swamp?
Archer: Nothing, it can happen anywhere at anytime, that's what makes it so terrifying.

Gandalf: I love your new hairdo, by the way.
Lana: Well if you like the collar, you're gonna love the cuffs.

Archer Quotes

Cyril: Why are you so scared of crocodiles?
Archer: Gee, I don't know, Cyril. Maybe deep down I'm afraid of any apex predator that lived through the K-T extinction. Physically unchanged for a hundred million years, because it's the perfect killing machine. A half ton of cold-blooded fury, the bite force of 20,000 Newtons, and stomach acid so strong it can dissolve bones and hoofs.

Cyril: Archer, do something!
Archer: Who am I, Alan Turing? He was also in X-Men, remember?
