Claptrap has some special, special friends.

So, you'd like to hear another story? Well, how about one where heroes from another world wander into the Borderlands, unaware of the horrors they will face? From that comes an up-and-coming manufacturer, a myth, someone who should not exist and the greatest bandit to ever live. No? Then screw you. It's Handsome Jack against anime teenage girls with transforming guns.
