Vin Diesel is at it again. The Guardians of the Galaxy voice actor has dropped yet another hint that he could be part of Marvel Studios’ 2018 release Inhumans, this time in the form of an image. The picture follows Diesel’s cryptic comment from August teasing his possible involvement. See the Vin Diesel Inhumans image and analyze its potential meaning with us after the jump.

Diesel posted this very interesting picture on Facebook without comment:

The actor has a history of teasing his upcoming projects on Facebook. He was the one who revealed last summer that he’d been in meetings with Marvel, and he kept fans guessing about whom he might be playing. The official reveal that he’d been chosen to voice Groot in Guardians of the Galaxy put the speculation to rest temporarily… but then Diesel got the rumor mill churning again by promising something else was in the works as well.

Diesel’s hints seemed to get more specific in August following the release of Guardians of the Galaxy. “I get the strange feeling that Marvel thinks I’m Inhuman…” he wrote on Facebook at the time. The new photo points even more blatantly in the direction of 2018’s Inhumans. That’s the Inhumans logo on his chest, and the line “Are you Inhuman?” comes from a campaign for the Marvel Comics storyline Inhumanity.

Fans have long speculated that Diesel could portray Black Bolt, the leader of the Inhumans. He doesn’t speak, because his voice has the potential to unleash great destruction. If Diesel is indeed playing Black Bolt, it’d be a funny bit of symmetry — Guardians of the Galaxy‘s Groot makes use of Diesel’s voice but not his body, while Inhumans‘ Black Bolt would require Diesel’s physicality but not his voice.

However, it’s worth taking Diesel’s hint with a grain of salt for now. Marvel Studios hasn’t officially announced any cast or crew for Inhumans. And it’s not due out until November 2, 2018, meaning there’s still time for any tentative plans to change.
