Marvel sent out the following teaser image today -- with art from Stuart Immonen -- simply asking, "Who is Mosaic?"

Considering the similar aesthetic to David Mack's original "Alias" covers, could this have something to do with the new "Alias"/"Jessica Jones" series that was teased at Emerald City Comicon? Is it Scarlet Witch's mouth? Or could this be the introduction of a new character entirely?

Expect to learn more soon, as Marvel tends to tease their new projects over the course of a week.
