O is for Orgasm Gas

Orgasm gas was developed by the archvillain Seductra for use in her various robberies and battles with the forces of good. As you might imagine, one good whiff of orgasm gas and the victim would be incapacitated for several minutes. Mind you, the actual orgasm only lasted a few seconds, but after that you just laid where you'd fallen and smiled all goofy like.

In one attack, Seductra gassed the President's State of the Union address pretty heavily, thus bringing much of the federal government to a halt. After that, the superheroes (and most ordinary folks) barely had the heart to hate her.

As with most villains, Seductra was undone by her own weapon. A lucky plasma bolt from Nuclear Girl caused the gas canister to explode in Seductra's face. A multiorgasmic woman by nature, Seductra spent the next 7 weeks going off like a fireworks factory. When she finally stopped, she had lost 43 pounds and was locked up in prison. To this day, she still goes off on a 15-30 minute orgasm-a-thon every few weeks.
