The next season of Doctor Who will have a new monster for The Doctor and Clara to defeat. It’s called Block 3 and he looks a lot like a BioShock’s Big Daddy. You can’t really tell from the teaser above, but you can check out a pick of the beast in the daylight after the break.
Expect to see Block 3 make its debut in episodes 5 and 6, which happens to be when Maisie Williams of Game of Thrones will also be guest starring on the show. Maybe she’ll be in the Little Sister role.
