Cancer, born between June 22 and July 22, is distinguished by deep reserves of empathy, love, and patience. These lovely traits are further enhanced by enormous emotional intelligence. As anyone who's ever been friends with a Cancer can testify, trying to hide exciting news, a glum mood, or a personal tragedy from them is impossible. At some point, you're going to ask a pointed question because a Cancer will "just have a feeling" something's up. Unfortunately, this sensitivity can curdle into something rancid. In a worst-case scenario, a Cancer can even become a hyper-possessive control freak like Jervis Tetch, Gotham City's infamous Mad Hatter.
"Batman: The Animated Series" sums the Mad Hatter up in Season 1's "Mad as a Hatter." Like most Cancers, his animated incarnation has a marked interest in other people's emotions — specifically, how he can control them through advanced neurotechnology. He's further defined by his obsessive passion for Alice, a bright-eyed co-worker with a fiancé Tetch loathes on sight. Here, we see how Cancer's loving tendencies can become manipulative, which pairs especially poorly with the blinding intensity of their emotions. Consumed by his own desires, the Mad Hatter brainwashes dozens of people, flees to a Wonderland-themed amusement park, and kidnaps Alice to serve as his mind-controlled paramour. Remember, Cancer: You have to make sure you invite people into your Wonderland, rather than force them.
