Crimson colored hair and a black uniform
And enough ammo to cause a blood storm.
Ex-KGB, she was one of the bad guys,
But she got tired of the betrayal and the lies.
Now she's part of S.H.I.E.L.D., but still not good.
When most heroes wouldn't kill a villain, she would.
She's as hot as she is deadly, which is a lot
Of help when she is behind enemy lines and caught.
She works her feminine, irresistible charms,
Then distracts them, beats them and leaves without triggering alarms.
The heroes are not immune from falling for her,
And she'll kiss them and give them a love-drunk slur.
One of the best agents and a dexterous fighter,
Who is this femme-fatale named after a spider?
