Ohba said that he created Matt because when Mello started to act alone Ohba believed that he would find difficulty in explaining the story unless Mello had a character to talk to. Ohba jokingly said that even though Matt may appear to play video games and have no other actions, Matt's existence was "important". In response to a question inquiring about which characters the creators had the most difficulty creating, Ohba cited Matt and said "Even I didn't know what kind of character he was!"
