At the Marvel TV panel at Comic-Con International: San Diego 2015 Friday afternoon, Marvel Studios revealed a newcomer to the Agents of S.H.I.E.L.D. cast.
Lash, one of the newest Inhumans in the Marvel Comics universe, is joining the cast of the show in some capacity. Marvel TV head Jeph Loeb told the audience at the panel simply that he's "coming," without revealing anything about the character's allegiance or how much he'd be used.
Lash was created in 2014's Inhuman #1 by writer Charles Soule and artist Joe Madureira. A hulking beast of an Inhuman, Lash hails from Orollan, a hidden city of Inhumans who believe the bloodline - and those who get exposed to the Terrigen Mists - must be kept pure (somewhat similar to the city of Inhumans in season 2 of the show). Strong and agile, Lash also has the ability to absorb and expel energy.
There was no word on exactly when he'd come onto the third season of Agents of S.H.I.E.L.D., though with the "Secret Warriors" tag and the idea that Skye will be out looking for other powered people (including Inhumans), there should be plenty of opportunity.
