Deadpool is pretty much the Foodie of the superhero world. However, the one food he is most often seen with is tacos. This food shows up on a lot of Deadpool merchandise, shows up in his comic books quite a bit, and even in the movie. (As an example of how much Deadpool is associated with tacos as of late, my brother has two Deadpool shirts. Both of them have a taco reference on them.)
Tacos aren’t his only favorite food. Like any foodie, he has a lot of them, adding some humanity to this foul-mouthed man of mystery. He is shown in the comic books with chimichangas, and the ever lovable Funko company created a Pop! Figure of Deadpool that comes with its own chimichanga truck. That is dedication.
