Connor ("Haneul" in the Korean version) is the main human character of Cubix who is obsessed with all types of robots. Connor was 13 years old when he moved to Bubble Town, and soon after joined the "Botties" by repairing the "Unfixable Robot", Cubix. Perpetually optimistic, and yet a bit hardheaded, he initially gets into trouble with his dad due to the latter's dislike of robots. He's best friends with Abby, and they often play 'virtual battle' video games at her house. He and the Botties hang out at his dad's doughnut shop and Hela's repair shop, the Botties Pit.

In the original Korean version, his name in Haneul and is voiced by Lee Mi-Ja. In the 4Kids Entertainment English dub, his name was changed to Connor and is voiced by Andrew Rannells.
