I've recently started watching Altered Carbon on Netflix and I've experienced somewhat of a déjà vu..
Takeshi Kovacs, the main protagonist, picks up a pink Hello Unicorn backpack along the way, that he uses for storing drugs and weapons. That contrast, of the girly backpack worn by a dark and dangerous warrior, somehow makes him ever bigger bad-ass.
Now every time I see him carrying it I cannot but think that I saw a similar trope somewhere on TV or big screen, and I really think that it might have involved a backpack too.
So the question is: is there a show or a movie that used a trope of a dark and gritty character acquiring and carrying around an item (possibly a backpack) that is in extreme visible contrast to his/her persona?
