Their partnership began the way many comic friendships do: with a fight. When they finally worked side by side, they discovered they made a surprisingly good pair, and they have teamed up on and off ever since, from 1970s street cases to modern Avengers missions.
Natasha is one of the more experienced heroes Spidey runs with, so their team-ups often have a mentor-and-student feel. She trusts him with her back in a fight, and he has learned that training and a clear head can matter as much as super-strength.
Spider-Man and Black Widow first met in Amazing Spider-Man #86 (1970). Natasha had just adopted her sleek new black costume and, watching the wall-crawler in action, became convinced she needed to test herself against him, even considering building a new heroic identity modeled on his. She sought Spider-Man out and fought him, only to realize she did not need his powers at all; her own skill and training were enough. The clash ended their rivalry before it started and set the stage for the respectful partnership that followed.
In recent comics Natasha remains one of Spider-Man's trusted fellow heroes, crossing paths as New York crime-fighters and as Avengers. She has headlined her own acclaimed solo series (Black Widow, 2020) and continues to operate as a top-tier spy and team player, ready to lend Spidey her tradecraft whenever a mission calls for a cooler, more calculating head.
Natasha Romanoff was raised and trained in a secret Soviet program as a master spy and assassin. She first appeared as an enemy of Iron Man before turning against her old handlers and becoming one of Marvel's most trusted heroes, serving with S.H.I.E.L.D. and the Avengers.
She has no traditional super-powers. Instead she relies on peak-human athletic skill, expert martial arts, marksmanship, and her signature Widow's Bite bracelets, which fire an electric shock. A special treatment in her training slowed her aging, so she has stayed at the top of her game for decades.
