The final piece of Marvel's Mosaic puzzle has arrived (via ComicBook), along with a teaser that ties the 'Mosaic' campaign to Uncanny Inhumans #11.
After asking "Who," "Where," and "Why" about Mosaic, it now seems that the name refers to a new Inhuman. Where this Inhuman fits into the Marvel Universe, or even Uncanny Inhumans, remains to be seen.
The term 'Mosaic' does suggest a combination of disparate parts, and with Spider-Man and Iron Man appearing in the image, one has to wonder if Mosaic’s power will be absorbing or combining the powers of other superheroes ... but that is just a guess.
The central conflict in Civil War II revolves around an Inhuman who can predict the future. Could Mosaic have some connection to that? Tying it to Civil War II would certainly explain the attention paid to Mosaic.
Coincidentally, Marvel icon Stan Lee created a superhero character called Mosaic - just not for Marvel. In 2007's animated film Mosaic for Anchor Bay Entertainment, the title character (voiced by X-Men's Rogue, Anna Paquin) had shapeshifting abilities due to being a member of a secret race living on Earth - no, not Inhumans - called Chameliels.
The solicitation for Uncanny Inhumans #11 ties the issue to Civil War II. Here's the full text:
