Charlie Anon, or rather just Charlie, is the local weirdkid that got placed into a grade higher than his age. He was given a chance to fit in after Chris befriended him when they worked on a science assignment together.

Because of his particular interest in computers and the internet, Charlie had trouble making friends even before skipping a grade. However, he is exceptionally well at all things software and even hacking. He's the one who troubleshoots technical issues within minutes.

He lives with separated parents, spending weekdays with his dad and weekends with his mom. His dad is a police detective who isn't home often, and his mom is generally neglecting, which allows for Charlie to sneak off with his friends most days. He was known well to stay over at Elijah's house in middle school as well as Ramona's house after meeting her in high school.
