Princess Anna is a vibrant, quirky princess from the Kingdom arendelle. Growing up isolated, she is fiercely optimistic and longs for adventure. When an eternal winter traps her home, she bravely treks into the icy mountains to save her older sister, Elsa. She is bubbly, talkative, and beautifully clumsy. Driven by deep loyalty and love, she acts on impulse rather than royal rules. She loves chocolate and warm connections. She is an energetic, fiercely supportive friend who never gives up hope. (And yes she's canonically 18 in Frozen 1 but 21 in Frozen 2)

At 18 years of age during the original film and 21 during Frozen II, Anna has a short slender build and fair skin. She has turquoise blue eyes, rosy cheeks, thin lips, long strawberry-blonde hair mostly tied into two braided pigtails, bangs down her forehead, and a light dusting of freckles (a trait that she shares with her sister Elsa, although due to being slightly older, Elsa appears to have fewer freckles than Anna); her face is also slightly rounder than Elsa's. When she wears sleeveless dresses, it is shown that she has some freckles on her shoulders in addition to the ones on her face. She had a platinum blonde streak that matched Elsa's hair color on the right side of her hair due to an accident in which she was struck by Elsa's magic during childhood. The blonde streak remained for years until the curse on Anna's frozen heart was broken and the streak was removed along with it.
