The main protaganist of Devilman who has the alter ego of the titular character. He is human or demon at times depending of the version and is often good. He is friends with/lives with Miki Makimura and Ryo Asuka (when Ryo exists).
In the TV series, Akira has many powers, such as being able to change his body size when he transforms, super strength, and energy blasts (referred to as "debiru arrow" or "debiru beam"). He also has enhanced senses, and the ability to see through illusions. Devilman flies on retractable, rounded wings. Akira is frequently seen using his emotions (such as his feelings for Miki Makimura) combined with his intelligence to defeat demons.
In the OVAs Devilman:The Birth and Devilman:Demon Bird Sirene, Devilman has many of the same powers; plus including teleportation, electrical attacks via his antenna, and fire breath; but does not refer to them as they are being executed. He also displays his use of enhanced senses more frequently.
Violence Jack has extraordinary strength. He can regenerate most of any damage he takes rather quickly, and split into different versions of himself (such as a woman or a giant child). He uses golden birds to carry his power and can infuse others with it, as well as use them to seek out those who need help. He can cause earthquakes, and has the ability to warp reality with his powers, as well as being able to exorcise demons and bring others back from near death. He can also turn into a bird and travel.
Miki Makimura is banging on his door and saying there is serious trouble. Akira jumps out of bed thinking its demons and falls on his horns and realizes he has transformed. He realizes the dream excited him and Miki walks in and freaks out but it turns out to just be a what if moment like in Scrubs. He goes on the light hanging fom the celing and she comes in. He is surprized by her being chibi and falls off. Akira is unnerved at the fact that he has become a chibi since he is a hero. Ryo Asuka then comes in to tell them that the fell into another world while sleeping...but Akira and Miki laugh since Ryo is also chibi. Ryo pionts his shotgun at them and tells them he`s gonna wack them if they ever laugh at him again. Later, Akira is outside, complaining about how most people don`t usually fire and a truck drives through him, leaving him confused. Ryo explains that in the Chibi world, they are overlapped in reality. Ryo says that if they can figure out why the chibi world exists, they can return to their real world/shapes. He eagerly agrees to work with Ryo and Miki, who is on the balcony, asks what they are doing. Akira asks what she is doing and mentions he can see her underpants before she says she can see an iceberg and he climbs up the drain to get a look. Akira is glad the demons have arrived. As they walk, they run into Jinmen, who has animal heads on his back. Miki wacks off his head with an axe and he somehow survives and they devour his body. Jinmen tirades and Akira trys to stomp him but Jinmen threatens to expose Akira as Devilman. Akira then agrees act nice with Jinmen. When they sleep, Gelmer captures Miki and when Ryo and Akira wake up they find a note. Jinmen reads Akira the note since Ryo-san shot Akira for freaking out at his morning face. Its a challenge from Sirene and Akira and Jinmen goes despite Ryo-san`s attempts to persuade him that it may be a trap and their mission is to save the world and get back their forms. At the glacier, they find Abel and they fall off and Akira devil kicks him off the glacier. After they go inside, Abel comes up the elevator and Akira Devil kicks him to the bottom of the glacier. Akira falls when the bridge collapses and doesn't fly since Jinmen says Akira`s secret identity will be exposed if he uses his wings and he makes a crater in the glacier. Abel tries one last time but falls in the crater and Akira goes up the elevator to the top floor. Akira throws a hose and uses it as a rope after he jumps to get to the part with Miki but doesn't make it to the top. He goes in a room and Sirene busts through the floor to grab Akira but gets Jinmen since he was on Akira`s head. Akira makes it to the top but finds that its Gelmer in Miki`s clothes and he froze in the glacier. Akira unfreezes Gelmer and they argue for a while until Akira transforms into Devilman and Sirene comes in. He is distracted by Sirene's bust and they talk for a bit until she hugs him and he passes out from the softness of her DD cups. He wakes up in bed in the nude and Miki comes in...to see Akira/Sirene in a room together...with Akira in the nude in bed. Akira tells her he is Devilman but Miki knows since she read the manga. Miki wants to know who Akira chooses and, after arguing with his conscience, he chooses Miki-chan since Sirene is "not his type". After hearing this, Sirene busts them out the window and Akira transforms so he can fight Sirene and save Miki (along with Jinmen) from falling. During the fight, they bust up the rooms/background and the Demon cleaning team comes in to clean up the mess made by the demons to keep humans from finding out about demons. The battle takes them out of the glacier and Ryo/Baron Ashura appear. Akira is glad to see Ryo and thinks the airship is cool when Sirene comes in and Ryo blows a hole in her! Ashura blows up the glacier and gets Sirene as Akira and everyone somehow survive (and that's just the first OAV).
In the Manga (based on “looking” at RAWs), Jun Fudo meets Akira in Hell (in the Third Circle for unknown reasons) after being sent there as part of some Demonic ritual where she gets violated, he then proceeds to give her a guided tour of Hell while fighting off various Demon’s including the combined form of Sirene/Kaim then Sirene in her original form soon after before she was incinerated and then brought back to life as well as to have some fun with Jun along with finding time to teach her how to fly much to the annoyance of Sirene. Akira then explains to Jun about how he ended up in Hell as well as being shocked that not only was the World “renewed” when he visited Earth from Hell, as a Ghost, but that “Devilman” was now a popular Manga. Jun then falls in love with Akira, he says that if Jun wants to get back to Earth she had to get to the Ninth circle of Hell where Satan is. Eventually Akira and Jun managed to get to the Ninth Circle where he says that Satan is an Angel who was trapped in Ice, but that turns out to be Zenon instead, after flying away from Zenon, Jun manages to crawl out of Hell but is uspet when Akira disappears after falling in love with him, though he merely became invisible to her. He appears again, still invisible, where Lan Asuka can sense him but not see him, it turns out that somehow Akira has been an unseen presence from early on in the Manga and has in fact fallen in love with Jun before remembering how Miki died and then being sent back to Hell. Later when Jun is about to get violated, Akira appears to save the day as a floating Demonic Skull (whose shape looks remarkably similar to Akira’s Devilman form), knowing somehow it was Akira, Jun took the Skull back to her apartment where she drew then designed a “Costume” to go with the Demonic Skull, which he tested out against several Demon’s while Jun was in the bath, and then appearing once again in her dream before saving her once again from being violated byVine-Man. In the final volume after being defeated by Sirene (who took over Aoi Kurosaki’s second Demon form and was still pissed at Jun), Jun walks back to her apartment sad that the Human Alliance was destroyed, when she was followed by a mysterious man that looked like a male version of Lan Asuka who proceeded to get jiggy with Jun before walking off, later on Jun is seen giving birth (in Giga form) to…..Akira whose body (that of a young boy) is still growing. As the world is ending, Jun is resting in her hospital bed when Psycho Jenny and male Lan appear before her, with the latter striping off her hospital gown. While that is going on, Akira (whose grown up so much since coming from Jun’s uterus that his clothes look like Mitsuomi’s from Tenjo Tenge) walks in on Jun / Lan being merged into one being, who turns out to be Satan who split then reincarnated himself into the “Renewed World” as two beings – Female Half: Jun Fudo and Male Half: Lan Asuka who used Demonic power to change himself into a woman as well as both of them becoming Akira’s “Parents” making him somewhat similar to that of the Antichrist, after digesting the fact that the woman he loved was not only his “mother” but a part of Satan himself, he happily decided to join Satan in the final battle against St. Michael and the Army of God, dooming Humanity and Earth.
Being one of Go Nagai's most famous characters, he has brief scenes in many other works.
- New Cutey Honey: A gargoyle that looks like Devilman is seen in episode 1 and Akira shows up in episode 7 for some reason.
- Devil Lady: The character Takeshi Maki is not only heavily based on the TV Akira, but has the same Japanese actor and outfit. Jun Fudo is basically a remake of Akira but a girl similar to how Violence Jack has a female form.
