Unlike other mental patients, Poison Ivy can be described as a genuine superpower user. She can create, cultivate, and command any plant to serve her, such as summoning giant vines to crush buildings, spreading deadly toxins through city flowers, or implanting tiny lethal spores into others.
Besides that, she is very intelligent, holding multiple doctoral degrees, and all her bodily fluids are toxic with various effects, capable of controlling minds, driving people insane, and even killing them in sweet dreams.
Modified by plants and toxins, she became a rapid regenerative ability user, capable of reviving even from mortal wounds when buried and watered.
In the comic world, even supermen from parallel worlds fall under her control. Currently, it's known that only Batman from the New 52 World is immune to this mind-controlling toxin.
Batman's firm will prevents him from being manipulated, but his mortal body can't fend off other toxins. There are numerous instances in the comics where Batman was near death from Poison Ivy's various toxins and was saved only by Butler Hero and Robin concocting antidotes.
Confronted suddenly with a bona fide superpower user like Poison Ivy unprepared, Cindy naturally felt uneasy, thinking it's better to leave quickly.
The herbicide Cindy mentioned was like calling a monk bald, a slap in the face right at the doorstep.
"How was that heard?" Cindy was somewhat bewildered, her hand slowly moving towards her weapon.
"All the lighting effects here, the lamps above and around us, are controlled by vines. Poison Ivy can rely on them to transmit subtle vibrational waves and hear everything we say."
Su Ming, however, didn't reach for a weapon but instead stood in front of Cindy, signaling no hostility with open palms towards Poison Ivy and Harley while explaining to Cindy.
"The other Deathstroke said correctly, sound is a form of vibration as well."
Poison Ivy relaxed slightly, retracting several snake-like vines back onto her body. If possible, she didn't want to engage with Deathstroke, let alone two of them.
"Our employer is also Ms. J, so since we all have the same goal of finding the Bat, why not sit down and have something to eat together?"
Currently, Su Ming and Cindy's search for the Bat had nothing to do with the Jester's task anymore; it was for saving Earth -11, but there was no need to tell Harley and them about it.
His mind raced as he quickly removed his helmet.
Since Harley isn't a match for him in direct combat, the threat comes from Poison Ivy alone. Her methods of attack can't be defended against by a helmet, so it's better to remove it, reveal his true face, divert their attention, and defuse the tense situation.
Because here on Earth -11, he's probably the only male supervillain.
"A man?!"
"A man?"
As expected, upon revealing his true face, both Harley and Poison Ivy, Ivy, exclaimed.
"Hmph." Cindy snorted coldly, also removed her helmet, and walked to Su Ming's side. Aside from their differences in gender and appearance, the two were practically carved from the same mold.
The same blind eye, the same armor and weapons, the same aesthetic sense.
Except their styles of doing things differed slightly.
Harley plopped down on the sofa, looking at Cindy, then at Su Ming, her big eyes full of curiosity:
"Alright, now we're actually interested in your story. As for finding the Bat, if we can't find him, we can't find him. I can't exactly mold one out of clay for Ms. J, can I?"
