Disney is opening its character vault for the new season of "Once Upon a Time."

During it's Comic-Con panel in Ballroom 20 on Saturday, co-creators and executive producers Edward Kitsis and Adam Horowitz teased fans with a montage of show openers that not only reviewed past plot points, but unveiled possible upcoming Storybrooke residents and storylines. Characters and items in these episode openers included Mulan, Aurora (a.k.a. Sleeping Beauty), a beanstalk (possible Jack reference) and a silhouette of Emma Swan's classic VW bug (Hmmm…"Love Bug," anyone?)

In addition to the episode openers, the panel also showed a teaser trailer featured Captain Hook breaking into Mr. Gold's (Robert Carlyle) pawn shop.

As for other developments, the showrunners did not reveal upcoming storylines, but reassured the Hall H audience that despite the fact that "Magic is Coming," the show will stay true to its fans.

"The show will not change from the show you loved last year. We will continue to go back and forth between the two worlds," said Kitsis.

"I never could have conceived the brilliance of the first few scripts, but as a viewer, it's everything I could have hoped for," said star Ginnifer Goodwin.

It was also confirmed that former "Lost" star Emilie de Ravin will join the show as a series regular.

The duo also revealed that the character of Dr. Whale (David Anders) will get his own backstory, and that auds will find out the identity of Henry's (Jared Gilmore) father.

"It's Sneezy," joked Kitsis. "I told you that Emma had a past."

Moderated by William Keck of TV Guide Magazine, the panel included Horowitz, Kitsis, Goodwin, Jennifer Morrison, Josh Dallas, Lana Parrilla, Meghan Ory, and de Ravin.

"We want to tell you new things and go beyond the stories we grew up with," said Horowitz. "Thanks to you guys, we have the opportunity to tell more stories this year.

"We premiered against football and the World Series. Thanks to you, we are here," said Kitsis.

"Once" is the the highest-rated new-scripted series on ABC and third most-watched drama overall on the net. The fantasy skein drew a 4.1 rating/10 share in the 18-49 demo on Sundays, and 11.8 million viewers overall.

Both Kitsis and Horowitz recently extended their overall deal with ABC Studios. The duo will stay with Disney for another three years.
