38 parts Complete Note, this takes place before Infinity War and ignores the bit in Black Widow where the Red Room, also known as the Black Widow Program, was terminated. Also ignores the Socovia Acords.
It stands to reason that there were others to escape the clutches of the Red Room other than Natasha Romanoff. Would they also be Avenger material? Would they maybe even help Natasha to see that her past does not need to haunt her forever, that she can let go and have what normal people have?
Luka-short for Lupus-was a widow. The Red room ran experiments to create the best widow. They experimented with cell manipulation. They've fused Lu's cells with wolf DNA and they can not know that they were successful-at whatever the cost.
Shortly after she was experimented on, Luka escaped and supposedly died from the inhuman transformation. However, she did not die and went on to live a life as an assassin-the only life she knows how to live.
When a string of strange, animalistic, maulings occur in New York in a time between battles when the Avengers have too much time on their hands, Captain America aids in the investigation. Little do they know that the perpetrator is an ex Widow experiment and that she needs their help.
Note, it's a slow burn and all characters belong to marvel other than the oc.
