The BBC has just released a bunch of images covering the characters, companions, and monsters of the 2013 spring return of Doctor Who.

Most of the images are from the early episodes. The ones heavily featured are from the first episode “The Bells of St. John,” the third which takes place on a submarine and features the Ice Warriors, and the fourth, which is a ghost story featuring Dougray Scott and Jessica Raine.

There is some interesting information released with the images. Jenna-Lousie Coleman’s character is referred to as Clara throughout, and is seen entirely in modern dress. Dougray Scott’s character is named Alec Palmer, and he seems quite friendly with the Doctor and Clara. Jessica Raine’s character is named Emma Grayling. The fez makes a return as the Doctor and Clara stand on the historic Thames waterfront next to the London Eye. The TARDIS is parked behind them as a crowd and a mime look on.

There is also a new alien revealed that looks like a cross between a Silurian and a Sycorax. It’s likely the same alien that is trapped in the box behind Jenna-Louise Coleman in the teaser below.

What do you think of the new images? Which is your favorite?
