Many of the ThunderCats, especially Jaga, have incredibly bushy eyebrows.
Aisling from The Secret of Kells definitely counts. What's odd is how they're black when she has white hair.
Transformers Prime demonstrates that this can even happen to robots. Check out Megatron and Starscream's eyebrows if you think otherwise.
Esmeralda in Disney's The Hunchback of Notre Dame has rather thick eyebrows for a Disney female, suggesting that the artists were going for an air of virility, or whatever you call it in women - it does work on some levels.
Turaga Vakama from BIONICLE didn't have eyebrows on his toy, but the animated movies gave him an absolutely massive monobrow wider than his mask that made his silhouette look as if he had horns. Sadly, neither of his prior forms shared this majestic feat in facial hair.
