Freminet is introverted, finding it very hard to speak with people he deems talkative. Freminet enjoys diving, finding the ocean a way to get away from the stress and express his feelings. Freminet has poor self-esteem, as he frequently believes himself to be useless outside of anything other than diving and tinkering with clockworks. He is also notably bad at lying. He is attached to his mechanical penguin, Pers, who he hopes to modify so that it could fly one day.
