Danger Beasts (危険種, kikenshu, lit. "danger species"), sometimes also referred to as Risk Species, are fearsome creatures in the world of Akame Ga Kill!. They are extremely hostile and will attack any human who dares to wander into their territory. Due to the increasing number of Danger Beasts, groups dedicated to hunting them were formed; the Partas Clan was one of such groups. Esdeath was born into this clan, her father being the Chief.
Some Danger Beasts' body parts have been used in the production of Teigu, Shingu, and Meihou, utilizing the unique qualities the Danger Beast had in life to imbue a piece of equipment with powers. Notable examples include Demon's Extract, which used the blood of a rare Danger Beast able to manipulate Ice, Incursio's invisibility from the Tyrant's natural defense or Cross Tail, whose threads are made from the fur of a Super-Class Danger Beast.
The most powerful Danger Beasts are categorized as "Super Class." These beasts are known to be extremely dangerous. It is unknown which criteria need to be fulfilled by a Danger Beast to be placed into to the "Super Class." It can be assumed that "Super Class" Danger beasts are very rare and many were killed because of the threat they pose.
Danger Beasts can also be created artificially. While the details of this process are unknown, Dr. Stylish was known to conduct experiments which resulted in the creation of new species of Danger Beasts. These new beasts were noted to have a humanoid look. Another case of relations between humans and Danger Beasts is the mixed heritage of The Path of Peace's leader. He apparently receives unique abilities from his Danger Beast heritage, while looking like an ordinary human. The details of his birth, however, are unknown.
There are also those who are capable of taming and controlling Danger Beasts through the use of techniques or Teigu; Merraid Oarburgh being a good example.
Danger Beasts in some countries have different names to refer to then, like in the Soukai Nation. Danger Beasts are called Freaks by the population. However, they held technologies that allow such country to forge a Meihou.
