Dr. Jail Scaglietti (ジェイル・スカリエッティ Jeiru Sukarietti) is the main antagonist of Magical Girl Lyrical Nanoha StrikerS and StrikerS manga.


Jail is probably named after Ferrari 612 Scaglietti, produced by Carrozzeria Scaglietti, an Italian car design company that also designed the Ferrari Testarossa (which, in turn, may be referenced by Jail's participation in the creation of Fate Testarossa).

The facility where Scaglietti is detained after the JS Incident, Gruen, was probably named after the Gruen Watch Co..


Jail Scaglietti is a very power-hungry man. Jail's main ambition is to control the Midchilda and conqueror it. Jail planted his DNA inside all of the Numbers, and when he was defeated they were to recreate him, As he was implanted with a mind of Unlimited Desire, Jail can be very cruel and maniplative to allies that help him such as Lutecia Alpine and Zest by recreating Zest in just so he could help the get the Relics and cloning Megane Alpine to make Lutecia to seek for the Relics as well. He created Combat Cyborgs and worked with Regius Gaiz of the Time-Space Administrative Bureau and killed many people with this attack. He also tries not shed that much blood since he likes life but will use his Gadget Drones to kill people if he hates them since they are in the way of the Unlimited Desire plan to recover all Lost Logia weapons. He also told his Combat Cyborgs they were doing this to save people, making several of them, follow him, while some questioned his intentions. Since he helped create Project Fate, Jail tries to convience Fate to come on his side to be his daughter. Through all Jail's cunning and evil personality, he does care about his Number daughters and treats them well and worries about them if they got hurt.


Jail bears a great resemblance to Ingram Prisken of Super Robot Wars. Like Jail, Ingram was responsible for the development of advanced weapons technology, created a female clone of himself as an assistant, briefly brainwashed two supporting heroines (one blonde and one blue-haired) into fighting for him, and eventually betrayed his creators.


In the Sound Stages, Jail Scaglietti is revealed to be an Artificial Mage, the end result of the top-secret Unlimited Desire project conducted by the TSAB High Council.[1] The project's goal was to obtain Lost Logia-grade weapons and magic for TSAB by creating a genius intellect wholeheartedly devoted to discovering and researching the long-lost secrets of Ancient Belka and Al-Hazard. The project was a complete success but the Council was ill-prepared for it, as Scaglietti soon went rogue using his vast expertise in ancient technology. Although pursuing his own agenda, he coerced the TSAB leadership to cooperate with him and to cover up his illegal activities, simultaneously threatening them and promising them the boons he was originally intended to deliver to them. One of such cover-ups was the Combat Cyborg Incident.

Jail Scaglietti is also responsible for starting Project Fate, which Precia Testarossa completed and used to create Fate Testarossa, who Jail has attempted to manipulate into joining his side.

In StrikerSEdit

In the beginning, Jail seems to only be sending his Gadget Drones from his lab after the Relics, but it soon is revealed that he is also making use of Lutecia Alpine's summoning magic by promising to revive her mother if she helps. Jail developed the Numbers which are named after numbers in Italian, as the name suggests, and has sent them to do his bidding as well. Jail's main ambition is to control the world by implanting a Relic inside Vivio Takamachi, which would allow him to use her to control the Saint's Cradle, and put her in Saint King mode for combat. Jail planted his DNA inside all of the Numbers, and when he was defeated they were to recreate him, but that plan failed when the Numbers either changed sides or were put in a position where that was impossible.

In Sound Stage XEdit

Jail Scaglietti appears briefly in Sound Stage X. He is still kept at the Gruen (グリューエン Guryūen) high security orbital prison over the Uninhabited World #9.[2] In return for his expertise in Ancient Belkan history, Scaglietti asks for red wine to properly commemorate Due's death, demonstrating that he does care about his Numbers, as opposed to just seeing them as tools, which possibly explains why four of them chose to remain with him when offered a pardon.

Alternate continuitiesEdit

Brave DuelEdit
