Stigmata (聖痕, Seikon, singular Stigma) are special tissues created by reverse-engineering from Nova cell cultures, which gives superhuman powers to Pandoras and Limiters. These tissues are usually implanted into the user's back.
Stigmata usually appear as small grey, hexagonal-shaped tablets with six trapezoids surrounding the inside and a small circle in the center.
In order for a female individual to qualify as a Pandora, she must go through a compatibility test. Depending on the results, she will have a certain number of Stigmata implanted into her. Most Pandoras would usually have up to four Stigmata implanted into them. However, some individuals, like Kazuha Aoi, can have as most as 20 Stigmata inserted. Unfortunately, this leaves the user at risk of turning into a Nova Form due to the quicker corrosion rate, despite being more powerful.
Following Kazuha's death in the 8th Nova Clash, the Chevalier began to limit how many Stigmata can be implanted into a Pandora. So far, the only Pandoras with more than four Stigmata are Charles Bonaparte, Cassie Lockheart, Rana Linchen and Satellizer L. Bridget (the former two both have five and the latter two both have six Stigmata, respectively).
A Limiter receives his Stigmata through a ceremony called a Baptism, in which a Pandora inserts one of her Stigmata into him. This creates an Ereinbar Set which allows the Limiter to perform Freezing.
A Stigmata Body (聖痕体, Seikontai) is a term referring to an individual who possesses a high quantity of Stigmata in his or her body, granting them unique abilities. Kazuya Aoi and Kazuha Aoi, the Aoi siblings, are the only two people in the series to possess a Stigmata Body.
After Kazuha Aoi's death in the 8th Nova Clash, some of her Stigmata were passed down to a few Pandoras. These Stigmata were called the Hero's Stigmata. Recipients of Kazuha's Stigmata are:
- Satellizer L. Bridget (6; 5% Compatibility)
- Cassie Lockheart (3; 90% Compatibility)
- Charles Bonaparte (2; 40% Compatibility)
- Julia Munberk (2; 36% Compatibility)
- Roxanne Elipton (1; 29% Compatibility)
It became apparent, that the Hero's Stigmata aches when a Nova is detected in the vicinity, evident when Roxanne felt pain when Amelia started to become a Nova and when Cassie asked Julia if she felt a 'certain' sensation.
Maria-type Stigmata are Stigmata that have been naturally produced (in other words, born with them). So far, Rana Linchen is the only Pandora who is born with one naturally.
The Injection Stigmata are stigma's created by the Seiga Heavy Industries corporation, these special stigmata are the energy source on which the newly formed Valkyries function. They are meant to be easy to implement "use and dispose" stigmata who have no further value once they run out of juice. Although they are meant to be recharged, no technology which allows that exists as of yet, however Seiga is still developing on this platform.
