Claymores

Claymores
Claymores are powerful beings created by the The Campaign Laconic Analyzation Youths More (CLAYmore) Association, originally meant to replace soldiers in war as unstoppable, emotionless killing machines. However, it is shown through the series that this is not the case, as only few Claymores are actually successful for what the Association originally created them for.

Successful Claymores
Sucessful Claymores are Claymores that are successfully created with Sociopathy/ASPD, Amnesia, and Manipulation abilities.

Almost-Successful Claymores
Almost-Successful Claymores that are almost perfect, except missing ability, or having an added disadvantage. An example of this is Rico, who has everything a Successful Claymore has, except with Psychopathy and ADHD, making her only Almost-Successful. (However, it's important to keep in mind that Rico was mislabeled, since she clearly feels emotions throughout the series, meaning she doesn't have Sociopathy/ASPD. This would mean she is technically Unsuccessful.

Mislabelling
The "Type" of Claymore is given to them after the operation and test. Claymores are capable of lying, changing later on.

An example of lying to be mislabeled is Rico, who is labeled as Almost-Successful; however, this is clearly not the case since she is a very emotional person.

An example of changing later on is Julie, who ends up becoming self-aware and garners emotions.

 * Julie Martin (changes in book 1 due to emotions and self-awareness)
