Preserved Pure Evils or Safeguarded Pure Evils are villains who are different versions from the original Pure Evils from a partial or complete duplicative change and still manage to preserve the criteria despite being another version from a story, this is basically a contrast to the Adaptational Pure Evil category where the Pure Evils for that status have the original versions that are not Pure Evil. What makes this category stand out on its own is that no matter the changes and interpretations the latter Pure Evil versions have in comparison to the original Pure Evil version, they still manage to find a way to be morally scaled to be a fully embraced atrocious person but in a newer take on it. In some ways, this can be like an Alternate Reality Pure Evil, but some of those may be adaptational with this category being specific to villains that don’t contradict the original version's evil scaling.

Composite profiles, such as a book being adapted to film, can also count if the other version is legitimately another version of the original with examples on why they are different versions, such as them making different decisions that never happened with the original, potentially having a different personality and motives, or are in a continuity different from the previous one, being on the degree of a partial or complete duplicative change to the continuity. To make the description more clear, let's say it’s a book-to-film adaptation if the film adaptation of the villain doesn't do any of these three listed things:

1. The villain alters the decisions the original has made that the character makes on their own accord.
2. The villain has category types that contradicts the originals character or doesn't have categories too specific to be compatible with the original, such as a character being clearly addressed within the story to not be a psychotic in the original or newer version, but is one in either the original or newer version with one that clearly isn't.
3. The villain has the events of the story drastically change as an effect of the villain's involvement on their adaptational accuracy, meaning if it is not a different timeline or universe that effects their narrative arcs significantly, then they won't fit in here. The reason why this rule exist is because it affects almost, if not everyone, to be part of the big changes in the story, with the original pure evil managing to be pure evil despite starting over. (Examples of composite Preserved Pure Evils in different timelines included Palpatine, Shao Kahn, and Professor Hojo) In some special cases, some versions might not be different despite the change in the continuity; by following the same original narrative until their service in the story like how it was before, these villains can't be classified as a Preserved Pure Evil due to not being a different version of the original.

Also note that if the story isn’t fully adapted but adapts accurately and the villain finds a way to be Pure Evil with that limited, yet at least fairly accurate, adaptation, then they won’t count. An example of this is Femto, who in the original anime, became Pure Evil in the cliffhanger of Berserk, a show that, while it made some changes, it wasn’t enough to drastically change the villain into being a preserved Pure Evil as he had no notable changes from his heinous decisions and virtually the same thing can be said with his movie trilogy, 2016 anime, and game selves as well.)

Added content doesn't automatically qualify for Preserved Pure Evils, as it may not alter the villain to change who they were before and still follow the continuity accurately. Two examples of this are Kamoshida and Shido, who in Persona 5: Royal, had no alterations that contradict their decisions and motives from the previous version.

A villain's fate doesn't always affect the later version to be a Preserved Pure Evil, as it may not change the exact details of the character to validate as a full-on different version as they may follow the original accurately. An example is Light Yagami, who had a different way of dying in the film series than he did in the manga.

Their opposites are Safeguarded Pure Goods also known as Preserved Pure Goods who are Pure Goods that meet the criteria as Pure Good who are adaptations of the Pure Good they are initially based upon.
