Guts from Berserk would be an interesting addition to an Akira Fudo crossover. Both characters have a dark and brooding side. They could bond over their shared experiences of fighting against powerful and often inhumane forces. Also, Light Yagami from Death Note. The clash between Light's sense of justice through his Death Note and Akira's more instinctual fight as a devilman would create a lot of tension and interesting plot points.
In a crossover fanfiction with Akira Fudo, characters like Lelouch from Code Geass could be great. Lelouch's strategic mind combined with Akira's power would be a formidable combination. They could plot against a common enemy, like an evil empire that rules over both of their worlds. Another good character would be Edward Elric from Fullmetal Alchemist. Edward's knowledge of alchemy and his quest for the truth could interact interestingly with Akira's journey as a devilman.
One Piece's Luffy would be a fun character to include. His carefree and positive attitude would contrast with Akira's more serious and often tortured nature. They could team up to fight a common foe, like a powerful pirate or a devilish entity that threatens both their worlds. And Mikasa Ackerman from Attack on Titan. Her combat skills and loyalty could pair well with Akira's powers as they face the Titans or other threats in a crossover scenario.
