A champion is someone who is really good at doing something. It could be playing a sport like soccer or basketball, or it could be playing a game like chess or video games. If someone is a champion, it means they have won a lot of awards and prizes for their skills. Think of it like being the best at something in your class, but on a bigger scale! Being a champion can take a lot of hard work and practice, but it feels really good when you do your best and win.
