Vin Diesel teases what teenage Groot could look like in Avengers: Infinity War.
The Marvel Cinematic Universe is celebrating its 10th year in 2018 with their biggest film thus far, Infinity War.
The fan-favorite character from the Guardians of the Galaxy films will have already grown into a rowdy adolescent by the time the upcoming third Avengers film rolls out next year.
With the apocalyptic nature of Avengers: Infinity War, death is imminent for some of our favorite Marvel characters and some fans could be reading too much into the Diesel-posted poster, presuming that Groot will bite the bullet due his sad-looking expression in the image.
