Five Hargreeves is brilliant, impatient, sarcastic, and brutally honest. He acts like the smartest person in the room because he usually is, but beneath his sharp attitude is someone fiercely loyal to his family. After surviving alone in a post-apocalyptic future for decades, he became practical, guarded, and willing to make difficult choices to save the people he loves.

He usually wears the Umbrella Academy school uniform: a blazer, shorts, knee socks, and polished shoes.

Luther Hargreeves is kind, loyal, protective, and often tries to keep his family together.
