Every hero will join forces in Avengers: Infinity War, but even with dire consequences, the Guardians of the Galaxy will maintain their humor.
But, with their next appearance being outside of their franchise, there was always the possibility that a slight change could occur.
Guardians of the Galaxy is one of the funnier MCU films, and the early reactions to Guardians of the Galaxy Vol. 2 are praising the humor (and more) once again.
James Gunn has infused the MCU version of the Guardians with humor since the first movie and it has been an integral piece to each character as well as their group dynamic.
