Elsa's powers were based on the concept of anxiety: The filmmakers wanted Elsa's powers to represent something deeper than just magical abilities. They chose to base her powers on the concept of anxiety, which is something that many people can relate to.
Strong and independent. Alongside from Sadness from Disney's Inside Out and Eeyore from the Winnie The Pooh franchise, Elsa is a metaphor for mental health. Ever since she was born, she's always been different while her parents, her sister and her royal subjects are literally powerless.
Elsa demonstrates powerful magical abilities from a young age. In Frozen, it's clear that Elsa's control over her power is directly related to the amount of control she has over her emotions. If Elsa is in a heightened emotional state, she can freeze entire landscapes without even being aware of what she's done.
As the Fifth Spirit, Elsa is able to awaken the four nature spirits of the forest: fire, air, water and earth. Despite her newfound connection with the elements, however, her powers are still primarily ice-based.
As I circled in the images above from the novelization and her Disney Wiki page, Elsa's official title is the Snow Queen. Throughout the first film, this title of hers is reflected by her signature snowflake, so this is her official symbol as the fifth spirit.
Anna's parents rush her to the sacred realm, where discussions with the trolls reveal that Elsa was born with her powers/ depigmentation and deafness, rather than them being due to illness or accident. Grand Pabbie troll heals Anna but removes her memories of Elsa's magic.
Elsa is never properly identified as asexual or aromantic, something that would help immensely to increase visibility and awareness. Considering Disney's record with LGBT characters (remember the underwhelming 'gay moment' in Beauty and the Beast?)
The Spirits of the Enchanted Forest, also known as the Elements, are five elemental beings prominent in Disney's 2019 animated feature film, Frozen II. Existing as mythical creatures that harness the magic of nature, these elements include water, fire, wind, earth, and a fifth spirit that bridges magic and humanity.
In the film, Olaf represents the happiness Elsa and Anna shared as young children. His desire to experience summer is symbolic of how Elsa wants to return to the old days of her childhood with her sister as her best friend.
The implication, and it's only ever just that, is that Elsa and Anna's mother is herself somehow attuned to the magical forces such that Elsa was given the gift of superpowers. (Why Anna never received such powers is equally vaguely defined: just as Elsa and Anna's father had no powers, so too would she be power-free.
The ice from which the palace is constructed is capable of taking on different colors, such as purple, blue, red and yellow, based on Elsa's emotional state (blue when she is happy or neutral, yellow or amber when she is angry, and red when she is frightened).
She's afraid that she's going to accidentally hurt someone else with her ice powers like she hurt Anna as a child. Her parents teaching her to hide her powers instead of trying to teach her how to control her powers was a terrible choice.
Although Elsa's disability is encoded as a magical ice power, the language the film uses to talk about her condition maps on to the experiences of people with physical, mental, and intellectual disabilities in recognizable ways.
Be Bold. Perhaps the most obvious message in Frozen is that it's good to be courageous. Elsa fleeing her home to live on her own was bold; Anna following her was even more so. Having a feisty streak can be a very good thing!
Elsa's discovery of being the Fifth Spirit in Frozen brings her closer to her parents, as Frozen 2 shows more of their history and how the Northuldra tribes were attacked by Arendelle's soldiers.
Elsa, however, is risk-averse, anxious, and self-doubting. This is her biggest test. She must accept her crown and scepter with ungloved hands. Should she slip up or let her emotions overwhelm her, she may let the magic out, revealing who she really is.
Elsa's opening narration reflects on grief and death. She has left her post with the cattle, staying instead by the wagons. One morning, she leaves the wagons to sit by herself after getting her period (she won't be carrying Ennis' child).
Honeymaren, a member of the Northuldra tribe who was trapped in the Enchanted Forest by the curse, could return for Frozen 3 as Elsa's girlfriend based on the two characters' shared chemistry.
The ice from which the palace is constructed is capable of taking on different colors, such as purple, blue, red and yellow, based on Elsa's emotional state (blue when she is happy or neutral, yellow or amber when she is angry, and red when she is frightened).
