Ahead of San Diego Comic Con 2015, new details about "Star Wars: The Force Awakens", including a new character and specifications of Supreme Leader Snoke, have been leaked online.

While it has already been revealed that the new trailer of the epic space opera will not be released in the international convention, speculations suggest that director JJ Abrams and team will have other surprises for the fans.

Although details of the cast members to attend comic con panel are kept under wraps, there is a buzz that Adam Driver, Andy Serkis, Domhnall Gleeson, Max von Sydow, Harrison Ford, Carrie Fisher and Mark Hamill could be part of the event to interact with fans and discuss about their characters in the upcoming sequel.

Meanwhile, new leaked information on the seventh instalment of "Star Wars" film franchise suggests that a new female character will be introduced in the film. She is described as a hotshot X-wing pilot named Jessika Pava with a call sign "Blue Three", according to Making Star Wars.

The website claims that the character knows Skywalker as the best pilot of the galaxy and starts admiring him after finding out that he defeated the Emperor.

Another speculation, based on a concept art, suggests that Snoke is not a human as he has snake head with closed mouth and the eyes of a reptilian. According to the description, he looks very evil with an angry sneer.

"Star Wars: The Force Awakens" will hit the screens on 18 December.
