Even the mightiest of heroes have to face Twitter trolls. 

As the latest Marvel comic flick Avengers: Infinity War breaks box office records, the film's stars read some of the meanest tweets about them on Jimmy Kimmel Live!

The Marvel Cinematic Universe (MCU) has produced some of the biggest films of the last decade and received global acclaim for its fantastic stories, but not all people are pleased. Chadwick Boseman and Samuel L. Jackson were among the actors from the Marvel flick to read some not-so-nice commentary about them from unhappy critics. 

Others think that Scarlett Johansson, who portrays super spy Black Widow, has the acting range of a stick of celery.   

Even Black Panther is getting some heat.  

"Okay, how did the coolest blackest dude in the galaxy end up with some whitebread-ass name like 'Chadwick'," one tweet read. 

The popular segment also featured a string of users comparing black actors to bugs, which may not be funny if you think about it too long. Don Cheadle (War Machine) was called a slew of different bugs, including a roach.  And for some reason, Sam Jackson was compared to a snapping turtle—which, admittedly, is true. 

"Also while I'm comparing old men to reptiles, ever notice that Samuel L. Jackson looks like a snapping turtle?" he read, while a side-by-side photo comparison appeared on the screen.

Jackson even chuckled. 

Avengers: Infinity War is currently in theaters.
