In addition to choosing a POV character, there is also the question of which voice to use; first, second, third limited, or third omniscient, and whether the story will be told in past or present tense. At the moment past first and third limited are most common within fiction.
Every character in a story has a perspective, a unique way of perceiving and interpreting the world around them, revealed to the audience through what a character says and does. Every story also relies on one or more characters to convey the story to the audience through their perspective. These are known as POV or point of view characters.
