- "A knight is an icon, on top of being a hero. A man made celebrity. The media acts to spread the threads of hope spun from the knights, and the public clings to them for support. In an era of universal warfare, it was all they had. Rather than simply calling them "elite units", they were given the name of "Knight" because the glorified image of a medieval knight, riding on horseback, was deemed suitable to boost public morale. In all folklore, the knight is the hero." Ep0 - Ch6
Its common for Knights to engage in different activities like launching a music album, taking advantage of their status as heroes of mankind. Examples: Instructor Milo and others in Ep0 - Ch6.
Knights have superhuman physical strength and speed, with Master Knights casually moving above the speed of sound and projecting shockwaves that can send armored vehicles flipping. This strength is often combined with superhuman abilities, known as Paranormal Powers. This allows the Knights to fight against the High Ranks, who can wipe out entire battalions of normal human soldiers.Every Knight starts as a Trainee and study in Planet Arin at the Knight Temple. When they are deemed as ready, the Knight Trainees will be allowed to take part in real battles, under the guide of Knights and Knight Instructors. It is unclear how a Knight Trainee can be promoted to be a fully fledged Knight as there is no test for that has been mentioned. However, base on the case of Anne and Pray, it is probably after they have proven themselves on the battlefield. A fully fledged Knight will receive his own AB Sword as the acknowledgement of their maturity. Depending on the fighting style that the number of swords could be varied. For example, Anne received a pair of AB Swords while Pray received one in their graduation.
Knights themselves are generally not capable of the same level of anti army operations that their Beast counterparts take part in, as few knights have the same flight abilities as Beasts, no DC Coat has the same defensive capabilities as the barriers of High Ranks and most Knights with Energy Projection Paranormal Powers cannot match the range or stamina of the Core fitted Beasts. However, there are still some exceptions among knight such as Dry, Pray or probably Anne with the destructive powers of Leonhard Ancient Sword style and Wave Techniques. Milo is also another example with his ability to control multiple fairies as demonstrated in Velchees and the recapture of Arin.
Among Knights, their ranking is determined by strength and accomplishments, strongest Knights are categorized as AAA Class, which is rare in the whole history of Knight Order. Currently, there are 3 knights ranked as AAA Class: Pray, Anne and later Dry. Lea Zail also can be considered as an AAA Class Knight as she can fight equally with Dry.
The total amount of active Knights at any one time is distressingly small for an intergalactic human empire under threat from Beasts. Dry asserts In Ep0 - Ch7 that the entire Eastern Order of Knights: "Had only 150 members to begin with. With so many dead, we can barely hold out."
With less than 150 Knights in the Eastern Order, even assuming a maximum disparity ratio of 1:2 to each of the four other Orders, minus Central Order which was annihilated on Arin by E-34, the total active numbers of Knights in the entire AE stand at barely over 1000. With all the Trainees at Central also devoured by E-34, recovery of Knight numbers would be slow at very best.
This shortage of Knights is one of the primary motives behind the events in Chapter 1 - Another Episode 2.
There are certain titles granted to Knights who surpass even other Knights in power and accomplishments.
- Master Knight
- A title given to the elite of the elite. All Knights who hold the "Master" is prefix have accomplished great feats in story. In Ep0 - Ch7, Dry states about Leo "That earned him the title of Zero Breaker. Now no one should be able to doubt his ... position as Master Knight." As Blue Ring was a middling Class C or D EX-Type Zero this implies that even for Master Knights, the title of Zero Breaker is an accomplishment that will assure any doubts about how you gained your title.
- Zero Breaker
- A title specifically given to those who kill a EX-Type Zero. It doesn't matter if it was a solo or battle, if a Knight manages to kill an Ex-Type Zero, then he is awarded the title. However, there is the difference in strength between Zero Breakers as those who managed to kill a Type Zero in a solo and those who defeated high rank Type Zero (said to be A class and above) are considered as superior. Anne and Pray are only Zero Breakers who had defeated SS class Ex-Type Zero.
- Top Sword
- The title of the strongest Knight. This one is held in CC 430 by Dry Leonhard, seven years since the previous confirmed Top Sword, Pray, 'retired' after the battle of Velchees. Milo is also known to have held this title, likely the Top Sword directly preceding Pray and it is quite likely that Anne also held this title for a time.
- Order Chief
- A title given to the head of a particular Chivalric Order. Most likely the most powerful Knight within their order. Their second in command is called the Deputy Chief.
The Knight Orders were established in CC 230 by the Mother Knight. Much like the medieval Knights who organized themselves into specific military orders, though unlike the ancient Knights, modern Knight orders appears based upon location of the Knight posted, with 5 branches, each with a specific base as headquarters, named after the four cardinal directions and Central:
- Central Order - The ruling Order. Headquarters were located on Arin. Deputy Chief is Kamad and Chief is Lime Gile. All Knights present at Central Headquarters in CC 430 were consumed by E-34, before the building was subsumed by Avalon.
- Eastern Order - Unknown Chief, most likely the Leonhard patriarch with Top Sword Dry Leonhard serving as Deputy Chief.
- Western Order - Unknown Chief.
- Southern Order - Unknown Chief. The Blue Spear unit is stationed there. Ex-chief is named Alf.
