Mistystar is a blue-gray she-cat with blue eyes.
- Mistykit was born in the ThunderClan nursery with her brother Stonekit and her sister Mosskit.

- She was the most playful out of the three.
- They played with Mousekit and Runningkit a lot.
- One snowy leafbare morning, their mother, Bluefur, took them out to Sunningrocks, pretending they were playing a game (called "Secret Escape") and handed them off to their father, Oakheart. Mosskit died from the cold.
- Oakheart took the two of them to RiverClan and gave them to an old queen named Graypool to raise.

- When Oakheart hands Stonekit and Mistykit off to Graypool, she realizes they smell like ThunderClan.
- Mistyfoot knew about Silverstream and Graystripe, but Silverstream trusted her to keep the secret.
- Mistyfoot ran away from RiverClan when Leopardstar created TigerClan with Tigerstar.
- Mistyfoot was made deputy when she returned to RiverClan after the battle with BloodClan.
