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 Spriggans 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".
 * Bradman: A very tall, extremely muscular man 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. Because of his fearful appearance, and due to the fact that he is seemingly able to kill people without the apparent need to touch them, his victims often compare him to a real "God of Death".
 * 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 woman who addresses her superiors as informally as fellow member Ajeel. Her Magic and abilities are currently unknown, but according to Makarov Dreyar she is a female knight that has conquered many battlefields, earning the title within the Alvarez Empire as the "Valkyrie".
 * God Serena: An exuberant man and the former holder of Rank 1 within the Ten Wizard Saints; meaning that 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, for reasons unknown.
 * 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 Spriggans for their inability to maintain respect and order. His Magic is Ice Magic and he holds the epithet "Winter General".
 * Jacob Lessio: A tall, middle-aged man of patronizing nature, he is regarded as a master in the art of assassination. As a member of the Spriggan 12, his magical caliber is also of an extremely high level; his Magic Power is stated to be on rivaled terms with the strongest Mage in the whole of Ishgar, God Serena.
 * Neinhart:
 * Wahl Icht: A jovial human-looking Machias, who creates machine soldiers that exploit his enemies' weaknesses and short-comings. His title within the Alvarez Empire is "The Adjudicator".
