Lassie is a coyote and Finn's adopted daughter. She has red and cream fur, blue eyes, and a black stripe down her back. She wears a white shirt, light brown overcoat and boots, red bandana, black jeans, and a cowboy hat. She fights using a lasso.

Lassie is mirrors her adoptive father's personality; impulsive, reckless and is almost the first one to get into trouble. This is usually seen when she challenges someone she deems as a threat on sight. Despite this, she thinks very highly of herself, evidently borderline egotistical. However, she is very brave and cares for others, namely Aasira, Thea, and Kaida. She is easy to talk to and normally doesn't make jokes at her friends and family's expense.

Lassie loves her adoptive family and supports them anyway she can.

Lassie isn't a big fan of the Talon Resistance as seen folding her ears back when they come close to her. Overtime, she begins to warm up to them.

Trivia:

Lassie is named after the dog Lassie.

Like Noxi, Lassie's ears can express her emotions by ear movement.

Lassie has spurs on her boots, which clink when she walks, similar to Ace.
