Daken Akihiro is a fiction character within the . Daken is the mutant son of Wolverine and his deceased wife Itsu. He possesses a power set similar to his father (e.g., healing factor, retractable claws), and was member of the Dark Avengers under the name Wolverine until their dissipation after losing the Siege of Asgard.
In 1946, as Wolverine is living in Jasmine Falls, Japan with his pregnant wife, Itsu, Romulus sends the Winter Soldier to kill Itsu. After Itsu's death, a mysterious man cuts baby Daken from his mother's womb and leaves her body lying on the floor. Daken survives this incident due to inheriting his father's healing factor. Sometime in the year 1946, Daken is placed at the doorstep of Akihira and Natsumi, a wealthy young and traditional Japanese couple. They take his presence as an answer to their prayers and raise him as their own. Though he is named Akihiro by his father, the servants and other families of the province secretly refer to the boy as Daken ( , "bastard dog" or "mongrel"), a slur on his obvious mixed heritage. As Akihiro grows, he is often teased by the other boys of the village. His harsh treatment over the years causes Akihiro to develop a very cold personality, directed at everyone except his father. One night, Natsumi confesses to Akihira that she doesn't love their adopted son and that, after long years of trying, she's pregnant. Akihiro overhears the talk and begins plotting. Within a year, after the birth of the baby, Akihiro confronts his mother and tells her that he has killed her son. Upon learning this, Akihira is furious and disowns Akihiro, who angrily responds that "Akihiro" isn't his true name anyway. Natsumi suddenly appears and tries to run him through, triggering the unsheathing of his mutant claws. He waves his arm, accidentally slashing Natsumi. Akihira, unable to force himself to harm his son, commits suicide. Romulus then appears to the boy for the first time and tells him that he is what the boy will someday become.
In the present, Daken disguises himself as a S.H.I.E.L.D. agent and infiltrates a facility where his father is imprisoned. He stabs Dum Dum Dugan and confronts his father for the first time. He slashes Logan across the stomach and leaves him to bleed on the floor, just as his mother was left many years before. Daken is revealed to have "aided" his father's escape, though not for benevolent reasons.
He is next seen in Berlin at the home of a woman with whom he has been cruelly, and romantically, toying. He allowed her to witness him kissing another man on a date, although unbeknownst to her, he later murdered the man to acquire a passport. Knowing that she would drink an entire bottle of burgundy, he secretly poisons it, resulting in her death. He had to end the relationship and her life so that no loose ends could be left to tie him to his crimes.
