|~ Akihiko Sanada, Persona 4 Arena|
Akihiko Sanada a sixth member from Persona 3.
Akihiko has short silver hair, grey eyes, skin of pale complexion and wears a white band-aid above his left eye. He wears a slightly modified school uniform of the Gekkoukan High School, where he replaces the standard jacket with a red sweater vest. Additionally, he wears black leather gloves. His standard summer outfit consists of a red v-neck t-shirt and white pants, while he is seen wearing a white jacket and a red scarf, as well as white pants on winter days. He is never seen without his gloves except during the trip to Yakushima while he is on the beach and briefly during the school field trip in Kyoto.
During his flashback scene in Persona 3 FES which takes place of an unspecified amount of time before the beginning of Persona 3, a much younger Akihiko is depicted, having softer facial features and a band-aid around his nose. He wears a red shirt under his white chemise and black pants.
In Persona 4: Arena, a 20 year-old Akihiko is seen. He has another band-aid on his right cheek, a cross shaped scar on the left side of his head, and stubble. He wears brown pants, and the left thigh of his pants is bandaged, while the right has several tears on it. He wears reddish brown boxing gloves and a matching cape. He does not wear a shirt, and he seems to have been injured by a huge animal, as he has three scars on his chest, and a few scars on his arms as well. In addition, he carries a machete, a bottle of water, large knife, and an evoker with him.
In the non-canon Persona -Trinity Soul- anime, taking place 10 years after the events of Persona 3, Akihiko is now an adult and considerably more mature. His skin is slightly tanned and he doesn't wear the band-aid above his left eye. Akihiko is seen wearing a black suit-like outfit together with a light brown collar shirt and red tie.
A cool and well-respected upperclassman, Akihiko is serious and determined, as well as cracking small jokes on small occasions (such as with Junpei, though this happens not as often), and tends to show his excitement for a big challenge. He also has an aggressive side, which he usually demonstrates when dealing with Shadows. He never gives up and always tries to get stronger in order to protect what is dear to him and feels guilty for not being able to save his sister, Miki, from the fire. He acts like an older brother for the younger S.E.E.S. members and especially in Persona 3 Portable if the player chooses to play as the female protagonist, Akihiko is shown to care a lot about her. Akihiko is on good terms with Shinjiro and keeps in touch with him even after he quit S.E.E.S., and cares a lot for him, as shown when Akihiko finds out about the drugs Shinjiro uses in order to prevent his Persona from going berserk. This part of Akihiko's personality is demonstrated once again after Shinjiro gets killed (or falls in a coma, in case the player manages to max Shinjiro's Social Link before his demise in female protagonist's storyline in the portable version), when he is seen grieving his death (or desperately begging Shinjiro to wake up, in the case of the coma).
- Akihiko's Persona, Polydeuces, is a something of a giveaway towards his connection with Shinjiro if looked at in small depth. Polydeuces - other than being a celestial body - is another name for Pollux, who is one of the Gemini Twins with the other being Castor, the latter of whom is the Persona for Shinjiro. Both of whom (Personas) share a similar physical stature, facial build, and focus on sheer strength.
- This connection also gives away Shinjiro's fate; Polydeuces was immortal and Castor was not, and in their myth, Castor dies (in response, Polydeuces requests to share his immortality with Castor, which leads to the two brothers forming the Gemini Twins constellation).
- Akihiko is left-handed, thus his fighting style represents a southpaw stance, but when using gloves the protagonist uses an orthodox style. He is also one of two Persona-users in the game who use his left hand when handling his Evoker (the other being Jin Shirato of Strega).
- Akihiko has a band-aid above his left eye, just like the protagonist of Devil Summoner: Soul Hackers, although his is in the right eye.
- The Shirt of Chivalry, a type of costume for males in FES and P3P, is noted for the kanji symbols on their back that symbolizes the character. Akihiko's kanji means "Fight" (闘), a very fitting sign for his character.
- One of the portraits in Persona 4 Arena is an edited version of the one used in Persona 3 Portable during All-Out Attacks and co-op attacks.
- In Persona 3 FES: The Answer, when the group is trying to see what is wrong with Aigis, Akihiko voice's turns into Mitsuru's voice, this only happens once.
- According to Zen United, the European publisher of Persona 4 Arena, Akihiko's appearance in said game was originally going to be modelled after Jason Statham and how he looks in the Transporter movie series. Soejima was asked to redesign him to look more "wild or rugged" by Wada, the game's director, after they noticed that no other character in the roster would be able to fill that role.
- In Persona 4 Arena, Akihiko reveals that he learned how to summon his Persona without the aid of an Evoker. He still uses it when executing Maziodyne and his Instant Kill attack, Earth Breaker, however. He also uses his Evoker during his fight against "himself" in story mode.
- In Persona 4 Arena, Akihiko's Cyclone Uppercut attack is based on his critical hit animation from Persona 3.
- Akihiko's favorite food in Persona 3 is mentioned by Shinjiro Aragaki to be "Anything with protein shit in it" only once. However, in Persona 4 Arena, Akihiko is often portrayed to be comically obsessing over proteins, whether he's under the Malevolent Entity's illusion or not.
