Attina is the first daughter of King Triton and Queen Athena and the heir apparent of Atlantica. Her age causes her to feel a strong sense of responsibility for her brother and sisters. Which causes them to see her as being bossy, but ironically, she herself is often bossed around when her siblings outvote her. She is highly well read and has a pet catfish named Fin-Fin. She is also known for having a calm and rational demeanor that carries a regal presence and shares a close bond with Ariel. She is also the most loyal and obedient to Triton. As such, she is terrified of letting her father down and is usually reluctant to participate in activities that he does not approve of. She always love her human brother Zach Loud.
