Aigis (Persona 3)

Aigis is the main deutagonist from the videogame, Persona 3, and she is also the main protagonist of The Answer, the epilogue and aftermath of Persona 3 FES. She is an anti-Shadow weapon (seemingly the last one in existence) and a member of S.E.E.S.. She is played by Maaya Sakamoto, who had also voice Eto Yoshimura from Tokyo Ghoul, Quinella from Sword Art Online: Alicization, and Akito Sohma from the 2019 reboot of Fruits Basket.

Why She Rocks

 * 1) When Aigis was first introduced, she is simply built just to exterminate shadows and follow orders. But as the game progresses and follow her Social Link, Aigis wants to know about why living is important as she learns about what it means to feel like a human.
 * 2) Much like  Schwi from the No Game No Life series, Aigis had fallen in love with Makoto even knowing she herself cannot die and so she will inevitably outlive him.
 * 3) In Persona 3 The Movie: #3 Falling Down, Aigis wanted to redeem herself and apologizes to Makoto that it wasn't her intention to take Mr. Kirijo hostage, crucify the members of S.E.E.S. and use them as sacrifices while being controlled by Ikutsuki.
 * 4) She's very powerful and strong, as she can stop a tank with her bare hands!
 * 5) * Aigis is also very athletic, as she can parkour everywhere against shadows.
 * 6) She has her fair share of funny and cute antics, like lying down on the bottom of the hot springs to bathe, or waking Makoto up.
 * 7) What's very impressive is that she herself is an Evoker, considering Aigis is a shadow exterminating robot, meaning she doesn't really need to shoot herself to summon her Persona.
 * 8) After the Dark Hour had finally ended, Aigis allowed Makoto to live like a normal highschool student for another month until graduation day, comforted Makoto during his final moments before he is put to sleep for eternity, and kept his Evoker to remember him by.
 * 9) Aigis becomes the next protagonist, and gets a lot of development in Persona 3 FES' exclusive chapter, The Answer:
 * 10) * She becomes devastated after losing Makoto, went back to being a machine, then at the end of the game, she develops into a strong-hearted girl with a talent of leadership, and regained her will to live, becoming more human than a machine. Yukari even admits that out of all the members of S.E.E.S., Aigis cared about Makoto the most, which is why out of all of them, she was the one who inherited his power.
 * 11) * After having a vision of Ken Amada dying at the hands of her sister Metis, Aigis had obtained the Velvet Room's Wild Card, and awakened to her Persona from Athena to Makoto's old Persona Orpheus.
 * 12) In Persona 4 Arena Ultimax, she told Yu Narukami that he reminds her of Makoto, meaning she still misses him.
 * 13) "I need your help!"

Bad Qualities

 * 1) It was very confusing and out of character for Aigis and the female members of S.E.E.S. when she caught the male members during the hot springs (If you fail), when she's always seen naked whenever they explore Tarturus.
 * 2) She is very unpredictable and random at times:
 * 3) * Such as breaking into the Makoto's room to wake him up five minutes early and requesting to be on standby in their room, which Yukari calls her out for.
 * 4) * Even going as far as to crash into Makoto, Junpei and Ryoji's room in Kyoto, claiming it was unfair that she and Makoto weren't in the same room.

Trivia

 * Aigis is the only protagonist in the entire Shin Megami Tensei series who can speak fully. Aside from Ren Amamiya from Persona 5 being voiced so many times inside palaces.
 * She is the second protagonist in the Persona series to be female, the first one being Maya Amano from Persona 2: Eternal Punishment, and the third being Kotone Shiomi.
 * While perfectly able to understand Koromaru's thoughts at first, Aigis loses this ability little by little when she awakens to the powers of the Wild Card in The Answer. As the Wild Card makes her become more "human," she starts losing some of her mechanical traits: humans can't speak with dogs, so now that Aigis is more like a human, she can't understand dogs anymore.
 * The spelling "Aegis" as appears in the original Japanese region titles is technically a misspelling of アイギス in English. The correct spelling, "Aigis" is the acceptable rendering of the original Greek. In fact, Aigis is the preferred spelling of the proper noun by contemporary academic standards.
 * In the ending anime scene of Persona 3 where the protagonist sleeps on Aigis' lap, there is skin where Aigis' white suit used to be on her neck, and she has ears instead of the robotic headphone-like pieces she normally has. This could be symbolic to her having become more human.
