Poison Ivy - Earth 2 - Suicide Squad: Kill the Justice League

A costumed meta-criminal, Poison Ivy, was an eco-terrorist and defender of the Green. She cared little for humanity and believed that it was her right and mission to return Earth to its natural state before the' expansion of human civilisation. She worked closely with Swamp Thing to achieve these goals. 

Recruited into Task Force X, she and Daphne were sent to Metropolis to help stop Brainiac's invasion. She did not survive. 

Her weapons and tech were scavenged by Lex Luthor in the aftermath of Brainiac’s invasion. 

After Luthor sought asylum on Earth-1, he supplied TFX with these weapons to use in their fight against the Coluan.
