9'α

Nine Alpha initially comes off as calm and polite, if a little enigmatic. When he first meets Hiro, he exhibits an easygoing attitude and is shown to be highly intelligent. Like all the 9’s, he acts as APE’s special ‘police force’ to moderate and keep the parasites in line, as well as updating Papa and the APE council with information regarding the development and behavior of the parasites. That being said, he knows how to talk to the authoritarian Papa, and is able to listen to him and offer his own advice, handling all of the APE’s highly classified missions without complaint. thumb|220xAlpha's smugness|alt= When his carefree exterior is shredded, Alpha is shown to be sarcastic and has a smug attitude, considering Parasites who are not of the elite level to be good-for-nothings. He is also arrogant, frequently smirking and demonstrating condescension towards anyone who is not either in his squad, or a member of APE. As a nihilist, he strongly believes that anything that possesses gender and emotions is an inconvenience, and he looks down on the human race. Alpha almost never shows emotions, and is rarely undignified, always acting calm and collected. Due to the emotional indoctrination, Alpha takes extensive pride in his duties, and believes laws and manners take the absolute priority over anything else, he reprimands Zero Two for fighting with him over him interrupting Kokoro and Mitsuru’s wedding so the two can be taken into custody, and he tells her not to resist Papa’s orders. He shows this side of him again when the subject of forbidden knowledge, such as emotion and reproduction, from the outside world is brought up. For example, he was visibly angry at Kokoro for having a baby book in her possession and hearing her openly question the ideals the parasites grew accustomed to. Alpha was utterly disgusted at her for rejecting APE’s ideals, and when he learned she and Mitsuru decided to get married and have a child, he promptly alerted Papa and APE of their ‘dangerous’ conduct. As he was created for the sole purpose to fight on the front lines, Alpha has a passion for combat and relishes in it, to the point he frequently smirks and licks his lips. He openly admits how much he enjoys killing klaxosaurs and finds it to be exhilarating. He holds a deep respect for Papa and the APE council to the point of viewing them as deities. He has disdain towards humans and is openly confused of their behavior, such why they eat candy, sleep, and most of all why they kiss. In the manga, after he is left half blind and seriously injured by 001, Alpha was prepared to accept his fate as a failure and be eliminated for becoming useless. However, he was surprised when Squad 13 put themselves in jeopardy to save him and Delta. Although he still felt confused of their human characteristics, Alpha felt in-debt to the squad and offered to give them medical care. During his time with Squad 13, Alpha demonstrates that he is not completely incapable of having emotions; Ikuno notes that even the 9’s can feel compassion when he worried for Delta after she went missing. Alpha demonstrates a kinder side by offering to help Squad 13 in the battle of Gran Crevasse to help Hiro reach Zero Two. Alpha has a mischievous side. He demonstrates this by flirting with Ichigo, whom he finds cute and admired her pride and dignity. He also shows a major interest in Hiro for being the only stamen to survive riding with Zero Two three times. Although he was created from Zero Two’s DNA and is thus her genetic clone, they despise each other to the point Alpha openly refers to her as a monster and mocks her for trying to humanize herself in order to remain in Squad 13. Despite his calm exterior, Alpha can exhibit violent behaviour when pushed to a breaking point. When he saw Delta and Epilson brutally murdered by VIRM, Alpha suffered a mental breakdown and began killing both VIRM and klaxosaurs in a moment of rage, no longer caring which group of monsters was the true enemy. Despite his indifference and inability to understand and/or show emotion, Alpha is capable of exhibiting sentimentality, as in the manga, he shed tears of sorrow when he learned his unit had been killed by the Klaxosaur Princess. Following Papa’s betrayal after revealing himself as the leader of VIRM and abandoning humanity to die, Alpha became visibly distraught. He exhibited signs of wanting to redeem his wrongdoings; firstly by offering to go with Squad 13 to rescue Zero Two, although he said he merely wanted to fulfil his duties, and second by sacrificing himself to save Hiro from the VIRM.

Nina Elpha is a rather short young man, his face framed by pale, honey blond hair, his long bangs low above his green eyes. He wears a special Parasite uniform emblazoned with white and gold, instead of the typical gray uniforms that other Parasite squads use. When in his FRANXX, Elpha, along with the others in his squad, sports a red battle suit. Like his fellow stamens, he appears with golden horns that appear to be holographic klaxosaur horns. In the manga, after his first battle against the Klaxosaur Princess, he lost his right eye, and wears an eye cover over the right side of his face.
