Akira Fudo

Akira is a teenager with black eyes and has prominent sideburnswith short black hair that is combed forward. At first, he had a rather unimpressive build and stood at an average height of 172 cm (5 ft 8 in), but after his transformation into Devilman, his physiology becomes more athletic and his stature grows to an imposing 186 cm (6 ft 1½ in) with black markings forming under his eyes as a result of Amon's influence.

As Devilman, he became somewhat larger than a normal human and grew large bat-like ears with a red crest at the front of his head and a pair of antennae. He had long marks above his shoulders that ran from his chest to his back and grew black fur and a tail below his waist line. Before his transformation, Akira was a kind and timid boy but would show a face of bravery when it was called for. Afterwards, however he became a whole lot more brave and confident, and in some cases perverse. He was best friends with Ryo Asuka and had been since childhood (although this is later shown only to be implanted memories they only where friends for a year before the Manga started when Satan take the identity of the real Ryo Asuka), he was deeply protective of Ryo. Unknown to him for a long while, Ryo was in love with Akira. He cared deeply for his adoptive family who took him in after his parents were too busy to care for him. Before his transformation, Miki was often the only friend Akira ever had and despite being talked down by her for not standing up for himself, Akira genuinely cared about Miki.

The Devilman Corps was an army headed by Akira Fudo that primarily consisted of the Devilmen, Rumi and Mikiko included, that had been wronged by the world.
