After capturing Batman, Wonder Woman, and Superman, she places them into the dreamworld and intends to use the solar energy emitted from Superman's body to open a gateway to bring the White Mercy—whom she considers as a daughter—over from the dreamworld. It is later revealed that Mongul deceived Poison Ivy and intended to conquer Earth using Superman as a vessel. Mongul is defeated by the White Mercy, using Batman as a temporary and willing vessel. As Poison Ivy and the White Mercy bid farewell to each other, the White Mercy uses her connection to the Green to make Poison Ivy lose her memories of the incident, so Ivy does not need to suffer any heartache.<ref>''Trinity'' (vol. 2) #2–6 (December 2016 – April 2017).

Upon examining it, Ivy realizes that the infected girl is already dead and Batman wanted to evoke her sympathy as he is actually seeking for a cure to combat the spread of the disease. She also reveals that, when she was still working at [[Wayne Enterprises]], she had presented her research wrongly as she thought Bruce Wayne wanted something to manipulate people but she was actually researching pheromones to make people feel good. Batman warns Ivy that an [[League of Assassins|unknown strike force]] is after her, because they know Ivy is able to pull biological weapons from the tree.
