Strength Level: Belladonna possesses the normal human strength of a woman of her age, height, and build.

Known Superhuman Powers: Belladonna possesses no known superhuman powers.

Weapons: Belladonna uses various chemical gases and perfumes that aid in her criminal activities. Her major type of gas is made up of neo-atropine, a substance derived from the belladonna plant. This gas has the property of making those who breathe it drowsy and eventually unconscious. It also serves to fill a room with a thick opaque vapor, which hinders visibility. A special side effect of the gas is that it dissolves Spider-Man's chemical webbing (or at least it did until he improved his web formula). She employs various other chemical agents.

Belladonna uses a gas gun to propel the various gasses. She also has a special system of tubing stitched into the lining of her coat sleeves, which is activated by an unknown mechanical linkage, for use in the event she is disarmed and needs to employ her gas.
