This is Boo. Earlier in the month Boo went to her first ever PAX, in Melbourne, Australia. Boo spent the weekend as a cosplay clotheshorse for her parents.
Over the course of the event she was everything from a tiny little Ezio to a tiny little Claptrap from Borderlands. As you can guess, photos with the wee one were in high demand.
