Artemis is a very kind and sweet person to pretty much everyone, whether they like him or dislike him. He tries to bring people together, mainly through sleepover parties and movie nights. He's very fashion-oriented and even made superhero costume designs for almost everyone in Class 1-B. However, he's also insecure and anxious. He doesn't believe he's a very talented fashion designer, despite everyone else knowing how talented he is, and is self conscious of things like his high-pitched voice.
