Suggested by Sonic Poison Ivy has a lot of plants which she can even have take physical shapes. They serve as an absolute defense that protect her against many opponents. This won’t work so well against someone like Killer Frost though. Killer Frost’s ice attacks are a perfect counter to Ivy’s plants as it will destroy them from the inside out with ease. Without her plants Poison Ivy has some hand to hand techniques but they won’t do much against Frost’s power. Killer Frost wins.
