Pestilence is a Kryptonian world killer. In the 31st century, she becomes known as Blight.

Powers

 * Altered Kryptonian physiology: While normally her capacities are no greater than a normal human of her physical conditioning, once empowered, she is becomes able to perform a variety of otherworldly feats. Even more, Pestilence's Kryptonian physiology has been genetically augmented from centuries of experimentation by Kryptonian scientists. Due to this, her powers are naturally greater than any normal solar-powered Kryptonian. It is unknown if she is more powerful than Superman, but it is likely that she is just as powerful as him, as she has been on Earth for at least 35 years; the same number of years that Superman has spent under the Earth's yellow sun but has augmented, much more potent powers, making Pestilence one of the most powerful beings in the multiverse. It has been implied by Mon-El; that Pestilence is the most powerful and deadliest of the kryptonian world killers.
 * Immortality: According to Mon-El; after 1000 years, Pestilence will eventually evolve into "Blight", implying that she doesn't physically age.
 * World killer link: The world killers appear to have a link with each other using Reign as a nexus point. This is evident as no world killers awoke until Reign did.
