Diana is 23 years old, she’s 185cm/6’1ft and she’s half-Korean half-American. She’s always giving orders, she’s a person very condescending and she thinks she's superior to everyone. Actually, yes she is superior to everyone but she’s exaggerating her power. When she asks/orders something to someone she doesn’t even say "please", because she thinks that people inferior to her don't deserve her "please" or her "thank you".
