Percy Jackson and the Olympians: Legends

Mallory is described as having green eyes, a reddish face and frizzy red hair. She has a short stature in comparison to her hallmates.

Mallory is shown to be brash with little filter, saying whatever comes to her mind. This has her sometimes come off as rude, but getting past that, she's a sweet person. As an einherjar, Mallory has developed a liking for battle. While she regularly insults and berates her hall mates, she, in fact, is very close to them and is considered the den mother of the group.

Mallory Audrey Keen is a Northern Irish Norse demigod, daughter of Frigg, before becoming one of the einherjar. She died while trying to disarm a car bomb during Bloody Friday and ended up in the Hotel Valhalla. She is the on-again-off-again girlfriend of Halfborn Gunderson. On 21 July 1972, which later became known as Bloody Friday, Mallory decided to join the attack after two of her friends were attacked by British officials. Loki disguised himself as one of Mallory's friends and tricked her into installing a car bomb on a school bus, claiming that soldiers were on board instead of children. n Valhalla, she would turn Halfborn Gunderson and Thomas Jefferson Jr., a Viking age berserker and union soldier who were enemies from over a century, into friends. For decades, she would think the old woman who gave her her knives was Loki in disguise and vowed to kill him with those very knives.
