10 Best Fakeout Endings In Comics

The daughter of assassins Lady Shiva and David Cain, Cassandra Cain spent her younger days solely being trained in brutal fashion to become a master martial artists. While she became well versed in a plethora of fighting styles, part of that strict training regime meant she wasn't allowed to speak - and thus, she was a mute when readers were introduced to her as the new Batgirl in 1999.

As part of 2005's Fresh Blood story, Cass and the Tim Drake incarnation of Robin find themselves caught up in one of the Penguin's schemes. Forced by Cobblepot and his cohorts to fight to the death or both be killed, these two heroes get surprisingly brutal with one another; the violent, aggressive ante upped by Cain mocking Tim for how he'll never be Batman, and Robin responding by slating Batgirl's oft-brutal methods.

With Cass knocked unconscious, Penguin wants to make sure the deed is done, and so he gives Robin a gun to make sure Batgirl really is dead. And jarringly, Drake doesn't hesitate in putting a bullet in his teammate.

The brilliant part of this, is that Batgirl's intense training means she's remarkably able to not flinch after being shot. The tragic part of this, of course, is that it shows how disturbing that training was.

Regardless, Cain soon gets to her feet as our two heroes take out the bad guys.
