Jenna is Aleu and Shadow's only daughter. She was born when her parents were separated, and lived with her mother for two months before she died. Afterwards, she lived with Shadow until he and Varadan died. At the age of one, she met Rex, and a year later, they became mates.

Little is known about Jenna, other than she was named after her grandmother. She was given her family's green bandana at the age of four by her father, the day before he died, as it was the only memory left of her grandparents and Shadow felt that it was time for her to have it. She was kidnapped by Alvaros as a hostage, but was rescued by Varadan and Shadow. She lived with them in Balto's old boat before becoming Rex's mate; after this, she moved in with his owners. What happened to her after Shadow and Varadan died is unknown, and will possibly never be found out.

Appearance: More of a dog than a wolf, a definite mix between her parents. She has caramel-colored fur with back spots on her back, and peach underbelly fur.

Age: 4, as of final appearance

Breed: 1/2 Wolf, 1/2 Husky

Likes/Dislikes: As very little is known about her, it is difficult to know what her interests are. However, it can be said for certain that, at least towards the beginning of her life, she hated being called "Pumpkin" by her father, much like Aleu hated being called Balto's "baby". She implied she likes spaghetti and even macaroni and cheese.

Personality: Much like her mother, Jenna is very protective and will stop at nothing to make sure those she loves stay out of harm's way.

Relatives: Aleu and Shadow, parents, and their respective families. Rex, mate. No siblings. Beyond this, unknown.
