Gepardi
From DALpedia
Gepardis are mostly humans, yet they have a very distinct difference from other races. They are the only known race that can capture the essence of a creature and obtain its abilities and take the creature's form. Gepardis for the most part are not considered to officially be a different race as some people tend to be able to learn how to use their abilities, yet becoming a Gepardi seems to have some genetic affect on the people who know this sort of magic.
