Veela

Veela are a beautiful species of human-like creatures with the ability to charm human males. When angered, they turn into reptilian-like creatures to frighten their attacker or threatener. Veela are known to cross breed with humans, spreading their physical traits of blond hair and blue eyes to female descendents. In the first two generations, there is not enough human DNA to produce a male descendent, which makes it very unlikely for a first-generation Part-Veela to be male.
