Bif Bang Pow!’s been using the holiday season as a way to reveal near product with a daily unveiling. Today’s reveal was particularly exciting, so it gets a post dedicated to it. As part of their 8″ classic Doctor Who retro-figures line, they’ve announced a Li H’Sen Chang and Mr. Sin. These figures are, of course, from the 4th Doctor adventure ‘Talons of Weng-Chiang’, an episode of note due to the giant rat that attacks Leela in the sewers of London. These figures are slated for September 2013 and can be pre-ordered now from Entertainment Earth.
