Spriggan 12

The Spriggan 12 (スプリガン１２ Supurigan Tuerubu) is an elite unit serving as Emperor Spriggan's (the emperor of the Alvarez Empire) personal guard.

Overview
According to Hyberion, the members of the Spriggan 12 (dubbed "Shields") are extremely skilled and powerful Mages, and around the same level of power as God Serena: the strongest Mage from Ishgar. The Shields also appear to do whatever it is they please and roam about, as when Zeref asked member Invel to gather the other eleven members, he noted that such a task on such short notice would be extremely difficult. Some also appear to operate independently of Zeref's wishes and act of their own accord, as Zeref said that the Alvarez invasion of Ishgar in X781 was due to some members of the Spriggan 12 not following his orders to stay away from the continent.

Members

 * Ajeel Ramal: An uncouth, dark-skinned antagonistic young man who goes by the title of "Desert King". He masterfully controls sand, befitting his epithet, and has a habit of referring to things he finds delightful or interesting as "sweet". He also leads his own squad within the Alvarez Empire, known as the Ajeel Squad, comprised of the warriors and Mages hailing from the desert regions of Alvarez.
 * August: An elderly, bearded and gray-haired man who dresses in a stereotypical wizard's garb, accompanied with a staff, and speaks in cryptic undertones. The full extent of his abilities are currently unknown, but it is said that he has mastered countless types of Magic and is feared as one of the strongest of the Spriggan 12, with his epithet within the Alvarez Empire being the "Magic King", partly demonstrated by his usage of Magic of incredulous power and its extensive scope. Also, befitting his status in power, August is the general of the Spriggan 12.
 * Bradman: A very tall, extremely muscular Etherious with an overall macabre appearance; wearing something reminiscent of an mask, as well as a dark demonic breastplate, partnered with metallic pauldrons and a long cloak. Monikered as the very "Grim Reaper" himself, he massacres all who is in his vicinity due to his particular body, as well as possessing the supreme collection of all the Curses of the Demon-affiliated Guild Tartaros that he exploits at his discretion.
 * Brandish μ: A scantily clad woman who controls a very advanced form of Magic that allows her to manipulate mass. She leads her own squad within the Alvarez Empire, known as the Brandish Squad, but seems not to care very much for her subordinates, as she has no qualms about sacrificing them to appease her apathetic, impatient whims. She also holds the epithet "Country Demolisher".
 * Dimaria Yesta: A cynical war empress that can majestically control time as well as her blades in battle. Blessed with great power by the God of Time, Chronos, her valor and reputation are so renown that Makarov Dreyar claims she has conquered many battlefields, earning her the title "Valkyrie" within the empire.
 * God Serena: An exuberant man and the former holder of Rank 1 within the Ten Wizard Saints; he was regarded as the strongest Mage in the entirety of the continent of Ishgar. He defected from his country and the Saints, all to join the Alvarez Empire and Zeref, implied by himself to have been for the sake of locating and killing the elusive final Dragon: Acnologia. An exceedingly powerful Dragon Slayer, he holds the epithet "Hybrid Theory" as he has been implanted with eight different Dragon Slaying Magics.
 * Invel: A polite, snow-haired young man who embodies the very definition of decorum, he is very stiff and takes rules and regulations very seriously, not fearing to chastise even his fellow Shields for their inability to maintain respect and order. His Magic is Ice Magic and he holds the epithet "Winter General".
 * Irene Belserion: A formidable witch renowned as the "Scarlet Despair", she is reputed to be the most powerful female member of the Spriggan 12. She dresses in a somewhat primitive outfit, the latter trait further accentuated by her staff, which is as tall as her and split into a pair of huge antlers covered with leopardskin near the top. She also leads her own squadron, the Irene Squad, headlined by her top two underlings: Juliet Sun and Heine Lunasea. A High Enchanter, Irene has the ability to bestow and affix her Magic Power onto all things, including the atmosphere and the very earth itself. The only named Magic she possesses, Universe One, is a brand new kind of Magic that allows her to reconstruct an entire country's geography to suit her fancy.
 * Jacob Lessio: A tall, middle-aged man of patronizing nature, regarded as a master at the art of assassination and a genius user of Stealth and Transport; Magics that can completely camouflage his presence and teleport his targets into an alternate dimension respectively.
 * Larcade Dragneel: A tall, rather young man with spiky hair, donning toga for clothing; characterized by his peaceful and harmonious attitude.
 * Neinhart: A defiant, effeminate man adorned in ornamental armor. He relishes being able to gaze into his opposition's hearts to seed out their historias, manipulating it against their will. He also leads his own squad within the Alvarez Empire, known as the Neinhart Squad, headlined by the Four Heraldry Knights.
 * Wahl Icht: A jovial human-looking Machias, who creates mechanized weaponry to exploit his enemies' weaknesses and short-comings. His title within the Alvarez Empire is "The Adjudicator".
