When fighting the Daleks she disabled their leader, Dalek X, by slicing her retractable claws through the bottom of its body and disrupted the Dalek-officer's anti-gravity generators. After the Tenth Doctor and the remaining crew of the Wayfarer destroyed the Dalek squadron they were fighting, Koral and Jon Bowman started a relationship on Earth. (PROSE: Prisoner of the Daleks)
As Koral was a member of an unnamed, cat-like race, not much was known about her species. Her reflexes were cat-like and she had many physical cat features. She also had powerful retractable claws that were made of a metal as strong as diamond.
