When you play a game or use a computer, sometimes you can make a different version of yourself called an "alternate character." It's like playing dress-up or pretending to be someone else. For example, if your name is Sally, you could pretend to be a character named Bob or Jane. You can choose what your alternate character looks like, what they wear, and what they can do in the game or on the computer. It's a way to have extra fun and try out new things!
