In this scene, the type of conflict occurring is “Man vs. Man.”
There are different types of conflicts internally and externally. In this case, we are presented with a scenario of two men fighting over the last piece of pizza. Because it is two physical people, the conflict type is “man vs. man.”
Man vs. Nature is a type of external conflict in which a character attempts to survive a situation regarding natural forces, one of the most primary being weather conditions. No natural element is involved here, meaning this answer can be ruled out.
In man vs. self, we are presented with the problem of a character amongst his or herself. The main character focuses on making decisions that challenge their ethics or values, or even their emotions! Because this scenario does not require emotions or internal struggles, man vs. self is incorrect.
Man vs. Society comes down to the margin between a personal value or belief compared to societal expectations. In this type of conflict, the character struggles to stay true to themself rather than conforming to what’s expected of everybody who desires social approval. Because this isn’t applicable to the scenario of two men fighting over pizza, it is incorrect.
Lastly, we are left with man vs. man, which is correct. In this conflict type, two physical beings come to a line of conflict amongst one another regarding opposing beliefs or values. This is applicable to the aforementioned scenario because two men believe they should have the last piece of pizza and are fighting over it. Therefore, Man vs. Man is the correct conflict type.
