Player character

From WoWWiki

A Player Character (PC) in World of Warcraft (WoW) is an in-game Alliance or Horde character controlled by you or another person (also known as a Player).

When you first start playing the game, you create a character for yourself, and you play the game as that character.

Also referred to as just a Player or a Character.

Some other names used:

• Alt or Main
• Avatar

NOTE: Player Characters are just one type of in-game character; see Non-Player Characters (NPCs).

Fighting another player character is called Player versus Player (PvP).
