The following is a list of characters from the Battle Angel Alita: Last Order manga by Yukito Kishiro. With the exception of a few characters who appeared previously in Battle Angel Alita, the majority of the characters who appear in Last Order are new. Some of them are based on fan submissions that were submitted to Kishiro for character ideas that he has adopted and expanded on.
New major characters
Caerula Sanguis
is one of several Last Order characters adapted from fan submissions that were solicited by Kishiro from his readers for character ideas. She is based a design called “Blue” by tfng, and the color blue is a recurring theme in the various aliases she has adopted. Formerly known as Vilma Fachiri, Caerula is first introduced as the Chairman of the Stellar Nursery Society, a small faction that operates within the main asteroid belt. However, she turns out to have a much longer history and background going back more than 700 years that parallel the creation of the current world within which the Battle Angel Alita universe is set, but was not revealed in the original manga series. As one reviewer notes, "in a very real sense Caerula's story is also the foundation of the present...her actions in the past played an instrumental role in bringing about the state of affairs that exists in Alita's current time."
Caerula is the last surviving Type-V mutant or "Cognate" as they refer to themselves as, a human who was infected by a retrovirus known as the V-virus, giving her vampire-like characteristics such as eternal youth. As a result of abilities that she has developed as a Type-V mutant, she is a formidable martial artist able to fully contend with cyborg opponents such as Alita, the series protagonist, even though she is still fully flesh and blood. Caerula is the protagonist of Battle Angel Alita: Last Order volume 9 (titled Angel's Duty by Viz Media), in which Alita does not appear once, making it the only volume thus far in both manga series to have this distinction.
Caerula is a highly skilled martial artist, a student of "48 schools and 125 divisions" of kung fu. She was a formidable fighter second only to Victor because of his skin hardening ability, and following his death, she might be peerless. Caerula is highly skilled in both hand-to-hand combat and sword combat (she fights with dual jian). Her long history of combat experience enables her to anticipate and counter her opponents while taking into account the surroundings and all possibilities. She developed a tactic known as the Eight Block Death Gate Array, a series of maneuvers designed to drive an opponent into an untenable position from which they can be killed in a final blow, which Mbadi acknowledges as inescapable once it has been executed.
As a result of being a Type-V mutant, Caerula's combat abilities are further enhanced. Because she is fully flesh and blood, more cyberized opponents tend to think that she is an ordinary human, which leads to underestimating her. She has more physical strength and heightened senses, such as being able to "see neural pulse flow", nullifying any speed advantage a more cyberized opponent may have over her. This is further enhanced by an acquired capability to ascertain the presence and trajectory of everything in her immediate environment during a fight, from the presence of her enemies, bullet trajectories, and minute details such as "the mice scurrying to take cover". Caerula's acquired regenerative ability can regenerate lost limbs over time and revive her from catastrophic injuries that appear to be fatal, such as her disembowelment following her fight with Victor Byron in ES 126 and her apparent "death" during her fight with Alita in ES 591. This ability appears to be aided by the consumption of fresh human blood, and she can completely suck an adult male dry, leaving him a desiccated corpse in seconds.
Sechs/Xechs
The sixth 'TUNED AR/GR Series 2' robot copy of Alita/Gally. After the shut down of the GIB, the abandoned AR-6/GR-6 renamed themselves Sechs, and found new purpose through combat, hunting down and destroying the other copies. Intending to ultimately destroy Alita in single combat, surpass the original, and earn the right to exist as a real warrior. After being defeated by Alita, and having the TUNED body destroyed, Sechs is temporarily put inside of Alita's old interactive interface to use as a body. After registering for the Z.O.T.T., Sechs transitions into the anatomically male Fizziroy body, made of cutting edge polyethylene materials, and different from his initial make as a replica of Alita.
