As you can see by this image, Boom Studios will also be producing some Muppet Comics. I've now read some interviews with the folks involved and I feel better about the whole thing. The first release of the Incredibles will be a mini series about Mr Incredible slowly losing his powers and trying to keep that a secret from his family. Sounds like good stuff that isn't aimed just at kids. The other titles announced will be Cars, Finding Nemo, Toy Story & Wall-E. Look for all the series to be about 4 issues long and then collected into a book format.
Boom Studios is hoping this will be the cornerstone of a larger line of kid-friendly comics featuring other characters as well.
