- "Now, that's enough for one night, dear. Tomorrow's a big day. It's first branching. Now, off to bed."
- ―Marella to Noctus and her children, Legend of the Guardians: The Owls of Ga'Hoole
Marella's egg hatched with a baby girl, who was given the name Eglantine. The family was very happy, except for Kludd, who didn't really care much for his little sister.
One night whilst Marella went out hunting with Noctus, Kludd pushed Soren from their nest, causing the latter to be snatched by a St. Aggie's patrol. When Marella and Noctus returned from their hunt, they were devastated to find Soren gone. They then gave Kludd strict instructions to mind Eglantine next time they went out hunting.
Some time after The Capture, Marella and her mate, Noctus, were killed, presumably by their eldest son, Kludd. It is unknown when they were killed, but it is most likely after The Capture.
Nyra pretends to be Marella, tricking Eglantine into visiting her and bringing her information about higher magnetics.
Marella and her mate came to see Soren and Eglantine as scrooms, seeing as their unfinished business was finally completed. She and Noctus then departed to glaumora.
Marella's role in the movie is very similar in the novels, except that she is not murdered by the Pure Ones. Instead, she and Noctus (her mate) travel to the Great Tree to greet Soren and the victorious Guardians after the battle with the Pure Ones.
Marella was a kind, loving mother who rarely ever got angry. She was sympathetic and understanding, and wanted only the best for her children.
- In the movie, Marella is seen at the Great Tree with her mate, Noctus, while in the books, she is dead when Soren and the Band find the Guardians.
- Her name was mistakenly spelled as 'Marilla' in the list of characters of The Capture.
- In the movie, Kludd resembles Marella more than his father.
- In the books, she is mentioned to look a lot like Nyra, but with a smaller face and darker plumage, but in the movie the two look nothing alike.
