One of Polar and Bear's children. Robin is North's partner-in-crime, often acting out with him in their shenanigans. However, Robin isn't as reckless as her brother, and will sometimes take Hoar's place in being the voice of reason. She loves her brother very much, but also keeps him in check.
She grows up to become a hunter, but hates having to deal with Hoar's bossiness. Overtime, she'd be ridiculed for her incompetence, even by the older wolves, causing Robin to lose confidence. Sick of dealing with harsh teammates, when she learned of North's mission to find the glacier, she was rearing to join.
Robin would see her mother again several months later when she visited the tundra. After learning from North and Moonspeaker about the pack's destiny, Polar promised to move the pack and catch up with her children.
Upon rejoining with her mother and the rest of the pack, Robin joined the Flakes as an official hunter. She deliberately chose not to join the Shards, as she didn't want to put up with Hoar.
