OVA
Description
Akira Fudo is a Japanese teenager living with the Makimura family following his parents' death. Initially timid and emotionally sensitive, his personality transforms dramatically after fusing with the demon Amon during a Black Sabbath ritual arranged by his childhood friend Ryo Asuka. This fusion grants Akira demonic attributes while preserving his human mind, leading him to adopt the identity "Devilman".

In human form, Akira has average height, a lean physique, brown curly medium-length hair, and prominent sideburns. He typically wears a red shirt under a black jacket with grey lining, black pants, and brown shoes. His Devilman transformation radically alters his appearance: his skin turns bluish-green, large wings with black exteriors and red interiors sprout from his back, and his body becomes muscular with spiked protrusions at the elbows and shoulders. Black fur covers his legs and genital area, and he gains a prehensile tail. His head features a red forehead, antennae, two pairs of small side wings, and black fur covering the rear.

Post-transformation, his personality shifts from compassionate and fragile to more assertive, sarcastic, and combat-focused. Core traits include unwavering protectiveness towards loved ones, especially Miki Makimura and Ryo Asuka, and intense hostility towards demonic threats. While often ruthless, his empathy surfaces when confronting demons like Sirene or Kaim who exhibit human-like emotions. During the conflict with the tortoise demon Jinmen, he is forced to destroy the preserved face of his friend Sachiko embedded in the demon's shell, causing him profound emotional distress despite its necessity.

Devilman's abilities include superhuman strength, speed, reflexes, and durability. Specific powers encompass flight via wings, energy projection through forehead antennae capable of disintegration or ensnaring, and retractable wrist blades called Devil Cutters for close combat. He also possesses pyrokinesis (fire breath), enhanced regenerative healing enabling limb reattachment overnight, thermal manipulation to vaporize foes by increasing body temperature, and acute sensory perception detecting high-speed movements. Even untransformed, he displays heightened physical prowess, such as lifting motorcycles or overpowering multiple assailants.

Within the "Cyborg 009 Vs. Devilman" narrative, Akira neutralizes the demon Pazuzu by ripping off his wings and bisecting him. This leads to a confrontation with Cyborg 009 (Joe Shimamura) based on misunderstanding, resulting in both losing an arm. After recovery, Akira allies with the cyborgs against the enhanced demon Atun/Azazel. Despite Azazel's accelerated regeneration, Akira inflicts critical injuries, enabling Cyborg 009 to strike decisively before Akira incinerates Azazel with fire breath. The alliance concludes with Akira departing with Ryo and Miki, reflecting on unresolved trauma from past conflicts.

Broader character history includes Miki Makimura's murder by paranoid humans during global demon-induced hysteria, shattering Akira's faith in humanity and triggering vengeful rampages. His final battle against Ryo, revealed as the angel Satan, typically ends in mutual annihilation or Akira's death, with persistent themes of unresolved love and betrayal. In sequels like "Devilman Lady," his spirit navigates Hell while manifesting residual protective instincts towards new allies.
