With Comic-Con currently in full swing at the San Diego Convention Center, Marvel Entertainment sent out a photo of a familiar prop that will likely be seen in Avengers: Age of Ultron, the powerful staff used by Loki (Tom Hiddleston) in Thor, Marvel's The Avengers and Thor: The Dark World. However, the staff is being held in a mysterious device, which you can take a look at below.

Back in December 2012, we reported that Tom Hiddleston's Loki will not be featured in Avengers: Age of Ultron, but his mystical staff will still play a big part in the story. The staff was last seen during an end credits scene in Captain America: The Winter Soldier, which gave us our first look at Avengers: Age of Ultron characters Baron Von Strucker (Thomas Kretschmann) and the siblings Quicksilver (Aaron Taylor-Johnson) and Scarlet Witch (Elizabeth Olsen).

It is believed that Loki's staff was used to give the brother and sister duo their superhuman powers, but that has not been confirmed at this time. It remains to be seen what this mysterious device is that is holding the staff in place, but perhaps we'll find out more details during Marvel's Hall H panel at Comic-Con later this weekend.
