It's simply Chemistry!!!

Ivy had been cooking up something that would help her land her man. As a highly skilled chemist and expert in biochemistry, it should be no surprise that the idea that she had formulated was centred around the world of chemicals, **** and potions.

She had doubled down and worked to developed a process that would breakdown a person's mind through the use of common and uncommon chemicals. She had tested it on a number of people who wouldn't be missed. She even stolen medical equipment to check the brains of the subjects. She was sure it would be the best of all of her previous mind altering love potions.

The first part was to catch the Bat-chlar, to bring him to the courting process. That was why she had unleased a plant minion to distract the Bat. As she snuck up, she saw him fighting against the veggie-beast. Finding her moment, she launched her knock out bomb at Bruce.

A large cloud of smoke covered him and he stumbled around a little before he fell.
