Akira is the youngest son of Dr. Nozomu Akatsuki. He is cheerful, carefree, and has a strong sense for adventure and justice. Akira and his brother Hikaru were left in the care of their aunt since their father had to go to America to work on his latest project: the DISK. Since Tony Stark wanted Akira and Hikaru to be proud of their father, he allowed both boys to attend the official presentation of the DISKs at the Raft. However, since Akira stopped on his way home to help a young boy find his mother, he and Hikaru missed their flight to America. Fortunately, Tony Stark send Pepper Potts with his private jet to pick the boys up.

During the demonstration, Loki and his henchmen, the Celebrity Five, crashed the party by releasing all supervillains from their cells and DISKs. While the Avengers tried to fight off the horde of villains, Dr. Akatsuki and his 2 sons found themselves cornered in the lab by Crimson Dynamo, who wanted the last Biocode Installer. Thanks to interference from Spider-Man, the villain was defeated, but Dr. Akatsuki was wounded in the process. Therefore, he gave Akira the suitcase with the installer and ordered both him and Hikaru to follow Spider-Man to the heliport. Along the way, the boys ran into 3 other kids: Chris, Jessica, and Ed.

When the group noticed King Cobra, who had taken Pepper Potts hostage, Akira encouraged them to try and free her. He approached King Cobra and offered to trade the installer for Pepper, but in doing so he lured King Cobra towards some containers, which the others then pushed on top of him. By then, Loki had already captured four of the Avengers, leaving only Iron Man to continue the fight untill he too was captured. When M.O.D.O.K. tried to destroy the biocode installer, the installer instead gave Akira and the other four kids a Biocode. This allowed Akira to D-smash Iron Man. Encouraged by Iron Man’s reappearance, Akira attacked Loki. In the brief scuffle, their biocode wristbands connected, which created a shockwave that scattered all DISKs containing the heroes and villains across the globe, robbing Loki of his army.

In the aftermath, Akira and Hikaru were both taken into S.H.I.E.L.D. custody and learned that their biocodes were incomplete. As a result, they could only temporarily release the trapped heroes from the DISKs. They also learned that their father had gone missing. When Loki, in his guise of Senator Robert, put S.H.I.E.L.D. out of action, Akira and Hikaru teamed up with Pepper Potts and Hawkeye to find the other DISKs before Loki could do so. They found Thor and Captain America, recruited Chris as their ally, and stopped the Hulk when the latter was mind-controlled by Diablo into attacking an Air Force Base. With 4 of the five Avengers back on their side, they attacked the ship of the Celebrity Five to free Jessica and Ed, and secure Wasp's DISK, thus completing their team. Akira became Iron Man's partner.

Once the team settled in Japan, Tony modified the roller skates Akira received from his father into the jet propelled booster skates. After a fight with Loki's henchmen at a construction site, Akira got War Machine as his second partner. During the battle with Loki in the latters Ice Palace, Akira managed to synchronize his biocode with his partner, thus giving Iron Man the ability to draw power from him and extend his time limit. This allowed the Avengers to defeat Loki and send him to the Dark Dimension, but unfortunately Dr. Akatsuki was sucked into this dimension as well.

When Red Skull started his plan to destroy the world and the Avengers had to split up to take out his 5 bases of operation, Akira and Iron Man were tasked with taking out the base guarded by M.O.D.O.K.. They were aided in their battle by Falcon. When Falcon was injured in the fight, Akira had to D-secure him to save his life, thus gaining Falcon as a third partner. Afterwards, Akira helped the Avengers defeat Red Skull's giant robot and defeat the villain for good, D-Securing him.

With Red Skull defeated and the Dimension Sphere now in their hands, Tony Stark planned to use the sphere's powers to open a gate to the Dark Dimension and save Dr. Akatsuki. For this purpose he contacted the Avengers' former member Dr. Pym to help him. Pym was still embittered towards the Avengers, but agreed to help. Helped by Pym and Pym's robot assistant Ultron, Iron Man build a device called the Dimension Gate. When Iron Man asked Pym to speed up the testing, Pym gave Ultron an upgrade to make him more humanlike and give him the ability to learn. This turned out to be a great mistake however, since Ultron now realized his superiority and decided that he should rule mankind. After first turning the Avengers' own base against them, but eventually being defeated there, Ultron uploaded his mind to the computernetwork and hacked into the S.H.I.E.L.D. computers to gain access to a military satellite weapon called Blue Javelin. Akira helped Iron Man defeat this satellite before Ultron could use it. When Ultron started his ultimate plan to subdue humanity to his rule with the help of his army of gigantic Omega Ultron bodies, Pym was asked to create a computer virus that could take out all Omega Ultrons at once while the Avengers tried to keep Ultron busy. Iron Man, Thor, Captain America, and finally Hulk all fought Omega Ultron, but where unable to defeat him. Fortunately, Pym finished the virus in time and Omega Ultron was defeated.

Akira was the only one of the 5 kids who did not fall victim to Baron Blood when the vampire attacked the group in a museum. Instead, Akira prevented the vampire hunter Blade from killing his friends and brother, and instead teamed up with him and Iron Man to find a way to save the others. They succeeded and Baron Blood was defeated. Afterwards, Blade warned the Avengers against trying to open a portal to the Dark Dimension, stating it to be too dangerous. Much to Akira's dismay, Iron Man complied to this request. While he was alone in the lab later that night, Akira heard his father call out to him and, against Iron Man's orders, he opened the portal. Thus, he allowed the villain Ronin to enter the base from the Dark Dimension and steal the Dimension Sphere.

Akira, along with the other kids and Avengers, then found himself fighting Ronin to prevent the villain from stealing the Treasures of Darkenss, with which the Celebrity Five intended to release Loki and an even more powerfull evil, Dormammu, from the Dark Dimension. When Iron Man discovered that Ronin was actually Akira's and Hikaru's father, Nozomu Akatsuki, he tried to hide this knowledge from the 2 boys, but the found out eventually when in a fight at the Great Pyramid Ronin's mask was destroyed.[1]. Akira was naturally upset at Iron Man for keeping this information a secret. However, a greater problem required their attention first; during his first battle with Ronin, Iron Man had been infected by some of the energy from the Dimension Sphere, which eventually resulted in him falling into a coma and his consicous mind getting sent into the Dark Dimension. Akira helped his team track down the DISK of Doctor Strange, and with his help, was able to save Tony from the Dark Dimension.[2]

When the Avengers discovered the plan to release Dormammu from the Dark Dimension with the help of a device called the Dark Gate, they came to the location of the machine to try and stop him. Although the heroes failed to prevent the gate from being opened and at least Loki to escape the Dark Dimension, Akira and Hikaru did manage to free their father from Dormammu's influence, restoring him back to his normal persona of Nozomu Akatsuki.[3] Now free, Nozomu built a new Biocode installer and gave Nick Fury a complete biocode. Fury used this new power to permanently release all captured heroes from their DISks. This however, meant that Akira and the others were no longer needed to help the Avengers. Moreover, because their limited Biocodes had been evolving beyond Nozomu Akatsuki's understanding, he considered it wiser to remove the codes. With much reluctance, Akira agreed.[4] The process also caused Akira to forget everything that had happened so far, at least untill he saw a news cast about the Avengers being arrested by S.H.I.E.L.D. in order to be delivered to Dormammu. With his memories restored, Akira made his way to the Avengers base to help out Iron Man.[4]

With great difficulty, Iron Man managed to convince Nick Fury to let Akira and the other kids stay on board the Helicarrier for the final offensive against Dormammu, stating that their prescence was still a boost to the Avengers' morale.[5] As such, Akira was present when the Avengers and S.H.I.E.L.D. set out to destroy Dormammu and the gate to the Dark Dimension with the 10 laser cannons that his father had helped to build. When Loki, in an attempt to keep S.H.I.E.L.D. from defeating Dormammu, infiltrated the Helicarrier and spread a rumor that the cannons were unsafe and would destroy the Helicarrier as well, Akira and his friends lured Loki out and exposed his scheme to the entire crew of the Helicarrier, restoring everybody's hope. With that taken care of, the Avengers and S.H.I.E.L.D. confronted Dormammu and defeated him.[5]

However, Loki seized this opportunity to D-Secure Dormammu and steal his powers for himself. As the Avengers tried to fight him off, Akira used what remained of his Biocode to give Iron Man his Build Up Armor for the final time. Unfortunately, even this wasn't enough to defeat Loki. The Avengers fell, until only Iron Man was left to continue the fight.[6] Iron Man was able to get Loki away from the Helicarrier and the other Avengers, and continued the fight on Techno Isle. When his father suggested using the Kree Mact to give Iron Man a chance against Loki, Akira and the others stole the Kree Mact and personally brought it to Techno Isle. Akira, being Iron Man's partner, got to deliver it to Iron Man. He succeeded in doing so with help of Spider-Man, Blade, and the Guardians of the Galaxy.[6] Powered by the Kree Mact, Iron Man was able to defeat Loki. Akira then helped to D-Secure Loki's last remaining army of Mindless Ones and then Loki himself, finally beating the villain.

With Loki defeated, Akira said goodbye to Iron Man. Akira promised him that he would continue to study, and one day build his own powered armor. 3 months later, Akira was indeed back to his studies, and had started working for S.H.I.E.L.D. as a lab assistant of his father. Then, one day, Iron Man sought him out again since the Avengers needed his help against a new threat.[6]



Red Biocode: Akira's DNA has been imprinted with the Red Biocode. This allows him to use the Tech variant of DISKs and to secure others using DISKs.
