A new book titled Lockjaw: Dog Days has shown up on Marvel Comics' website database. No details on what this could be, but this would come just one month before the character's live-action debut in ABC's Inhumans title. The dog-like character previously led two Pet Avengers miniseries, as well as appearances frequently in various Inhumans titles.
A "Year One"-style origin series, Inhumans: Once & Future Kings by Christoper Priest and Phil Noto, was previously announced to debut in August.
Look for more on this as part of Marvel Comics' August 2017 solicitations, which are scheduled to be released this week.
