Three is talented at writing. He actually wrote for 'The Number Playground Chronicle'. He's rather short-tempered, outgoing and he's not afraid to voice his opinions, whatever they are. Despite being irritable, he has a soft spot for One and he deeply cares about them. He always helps One with certain tasks, since One is armless. He tends to hold grudges, especially with Five. He sees Five as a frenemy. He hates being called 'Thirteen' whenever he and One are together.
