A common trope that frequently appears in the realm of entertainment is that of the "Badass and Child Duo." This trope relates to a battle-hardened warrior, usually experienced in killing, who is forced to escort a child to a safe haven or protect them from those who wish to harm them. Usually, the two characters are not related, meaning the deep relationship that builds between them is one of the key focuses of the story.

This trope has been getting a lot of use lately, with award-winning video games God of War and The Walking Dead using it as a major focus for their stories. Its use is universal, however, with film and television also getting in on the action. With The Last of Us show proving to be a massive success, it causes one to look back at the other movies and TV shows that told great stories featuring an adult and child partnership.
