A Malfested (referred to as Evils (イヴィル Ivuiru?) in the Japanese version and Outsiders (異分子 Ibunshi?) by the Aval Organization) is a being corrupted by the power of Soul Edge. They serve as the primary antagonists in the Soul series. Initially thought to have been created by the Evil Seed, it is later revealed that the Evil Seed merely transformed them from humans into mutated monsters. In Soulcalibur Legends, Malfested initially were on the side of the Ottoman Empire, but after the defeat of Barbaros, they joined the Masked Emperor of the Holy Roman Empire (Non-canon). Malfested that protect shards of Soul Edge are known as Guardians. Lizardmen, Berserkers and Dragon are both types of Malfested.
Malfestation is caused by Soul Edge's curse. It is regarded as a type of cancer, or even an entirely new parasitic organism. However it causes enhanced physical abilities among it's victims, and can cause victims to mutate into more powerful states of being when they experience intense emotion. It can also causes some victims to gain what appears to be some kind of immortality.
The traits gained by the victims are possibly based on their personality and physique, as Tira may have stopped aging due to being part of a clan that valued survival above all else. Male Malfested often display physical transformations while females generally don't, though exceptions like Pyrrha Omega, and Maki exist. When Cervantes became malfested, he was a zombie due to being revived by Soul Edge. When Raphael and Amy became malfested, they gained vampiric traits and abilities.
Malfested animals that act as minions for Soul Edge are known as Watchers. Cervantes' shark, Nightmare's hawk, and Tira's crows are examples of Watchers.
- Malfested: Regular malfested only features their glowing eye pupils. By giving in to the evil they can push their body to the limit to gain enhanced strength and speed.
- Malfested (Mutated): Upgraded versions of regular malfested feature not only all glowing eyes (both scalars and pupils), also featuring the marks that shows the beginning of their mutations. Some retain their sanity at this stage while most become mindless beasts.
- Malfested (Fully Transformed): The true final form of malfested mutation lines, transforming the host’ body parts into much or monstrous. However, this form is exclusive to male. Fully transformed malfested are no longer human and are avatars of pure evil, they are extremely rare and even one will cause the deaths of untold thousands.
