SUPERHUMAN AGILITY
Black Widow is a deadly one-woman fighting force. An expert in many forms of martial
arts, she is also a skilled gymnast and possesses superhuman strength, speed, agility,
and endurance.
ESPIONAGE
Black Widow is as deadly in darkness as she is in light; as a highly trained super spy,
Natasha Romanoff stands among the greatest covert assassins in the world.
SLOWED AGING
In addition to her deadly skills, Romanoff also ages at an incredibly slowed rate—much
like Captain America—thanks to a variant of the Super-Soldier serum that she was
once given.
