In terms of personality, she greatly parallels and resembles her father, as the two both tend to be unruly, impulsive, and loud. She tends to be ungraceful and has bad manners, and is extremely tomboyish.

She also seems to be skilled in sword fighting, as shown in the Brave featurette 'Cutting the Class'.

She is very athletic and enjoys nothing more than riding her horse Angus and practicing her archery, of which she is the best in the kingdom. Rather than being a damsel in distress who is subservient to the customs, traditions, and social restrictions her society places on her and expects her to follow, Merida openly rebels and defies her heritage as a princess and would like for nothing more than to be a normal girl. Merida is a very bold, brave, daring, courageous, stubborn, rebellious, and headstrong girl who does not fit the stereotypical princess role. She loves her family, but she wants to control her own destiny. She spends her days practicing archery, riding her horse Angus, and exploring the world around her. Merida is a princess by birth and an adventurer by a spirit. Despite her outgoing, forceful, headstrong, and willful personality, Merida does have a playful softness of heart particularly when it comes to her younger triplet brothers, Harris, Hubert, and Hamish. She is also skilled in sword-fighting and racing across the countryside on her horse, Angus. Merida has honed her skill in archery and is one of the most skilled archers ever seen.

Despite Elinor's desire to see Merida as a proper royal lady, Merida is an impetuous girl who wants to take control of her own destiny. Queen Elinor's expectations of her daughter cause Merida to see Elinor as being distant while also causing friction between the two. Princess Merida is the headstrong and free-spirited 16-year old tomboyish, willful daughter of Queen Elinor, who rules the kingdom alongside her husband, King Fergus.
